It is generally believed that special steel refers to steel with special chemical composition (alloying), produced by special process, special structure and properties and able to meet special needs. Compared with ordinary steel, special steel has higher strength and toughness, physical properties, chemical properties, biocompatibility and process properties.

The definition of special steel in China is similar to that in Japan and the European Union. Special steel is divided into three categories: high-quality carbon steel, alloy steel and high alloy steel (alloy element greater than 10%), in which alloy steel and high alloy steel account for 70% of the output of special steel. The main steel types are excellent special carbon structural steel, carbon tool steel, carbon spring steel, alloy spring steel, alloy structural steel, ball bearing steel, alloy tool steel, high alloy tool steel, high-speed tool steel, stainless steel, heat-resistant steel, as well as superalloy, precision alloy, electrothermal alloy, etc. At present, there are nearly 2000 special steel grades and about 50000 varieties and specifications in the world. In addition to a wide variety of special steels, they also show different characteristics from ordinary steels in specifications. In addition to plates, tubes, wires, strips, rods and profiles, there are also composites, surface alloying materials, surface treatment materials, precision forgings, precision castings, powder metallurgy products, etc.

1.Overview of steel grade representation in China

Steel grade, abbreviated as steel grade, is the name of each specific steel product. It is a common language for people to understand steel. The representation method of steel grade in China is based on standard

It is specified in the method for brand representation of iron and steel products (gb221-79), which is expressed by the combination of Chinese Pinyin letters, chemical element symbols and Arabic numerals. Namely:

① Chemical elements in steel grades are represented by international chemical symbols, such as Si, Mn, Cr. Mixed rare earth elements are represented by "re" 

② Product name, purpose, smelting and pouring method, etc. are generally represented by abbreviations of Chinese pinyin.

③ The content (%) of main chemical elements in steel is expressed in Arabic numerals.

2.Classification and description of steel grade representation in China

① It consists of Q + number + quality grade symbol + deoxidation method symbol. Its steel grade is marked with "Q", which represents the yield point of steel. The following numbers represent the yield point value, and the unit is MPa. For example, Q235 represents the yield point( σ s) 235 MPa carbon structural steel.

② If necessary, symbols indicating quality grade and deoxidation method can be marked after the steel grade. The quality grade symbols are a, B, C and D respectively. Deoxidation method symbol: F represents boiling steel; B represents semi killed steel: Z represents killed steel; TZ represents special killed steel, and killed steel can not be marked with symbols, that is, both Z and TZ can not be marked. For example, q235-af represents class a rimmed steel.

③ Carbon steel for special purposes, such as bridge steel and marine steel, basically adopts the representation of carbon structural steel, but the letter indicating the purpose is added at the end of the steel grade.

2. High quality carbon structural steel

① The two digits at the beginning of the steel grade represent the carbon content of the steel, which is expressed in tens of thousandths of the average carbon content. For example, for steel with an average carbon content of 0.45%, the steel grade is "45", which is not a sequence number, so it cannot be read as 45 steel.

② For high-quality carbon structural steel with high manganese content, manganese element shall be marked, such as 50Mn.

③ Boiling steel, semi killed steel and high-quality carbon structural steel for special purposes shall be specially marked at the end of the steel grade. For example, the steel grade of semi killed steel with an average carbon content of 0.1% is 10B.

3. Carbon tool steel

① The steel grade is marked with "t" to avoid mixing with other steels.

② The number in the steel grade indicates the carbon content, expressed in thousandths of the average carbon content. For example, "T8" means that the average carbon content is 0.8%.

③ For those with high manganese content, mark "Mn" at the end of the steel grade, such as "t8mn".

④ The phosphorus and sulfur content of high-quality carbon tool steel is lower than that of general high-quality carbon tool steel. The letter "a" is added at the end of the steel grade to show the difference, such as "t8mna".

4. Free cutting steel

① The steel grade is marked with "Y" to distinguish it from high-quality carbon structural steel.

② The number after the letter "Y" indicates the carbon content, which is expressed in tens of thousands of the average carbon content. For example, the steel grade of free cutting steel with an average carbon content of 0.3% is "Y30".

③ For those with high manganese content, mark "Mn" after the steel grade, such as "y40mn".

5. Alloy structural steel

① The two digits at the beginning of the steel grade represent the carbon content of the steel, expressed as a few thousandths of the average carbon content, such as 40Cr.

② The main alloying elements in steel, except for individual microalloyed elements, are generally expressed in a few percent. When the average alloy content is less than 1.5%, generally only the element symbol is marked in the steel grade without the content. However, if it is easy to be confused under special circumstances, the number "1" can also be marked after the element symbol. For example, the steel grades "12CrMoV" and "12Cr1MoV", the chromium content of the former is 0.4-0.6%, the latter is 0.9-1.2%, and the other components are all the same. When the average content of alloy elements is ≥ 1.5%, ≥ 2.5%, ≥ 3.5%... The content shall be indicated after the element symbol, which can be expressed as 2, 3, 4... Etc. For example, 18Cr2Ni4WA.

③ Vanadium V, titanium Ti, aluminum Al, boron B, rare earth RE and other alloy elements in the steel belong to microalloyed elements. Although the content is very low, they should still be marked in the steel grade. For example, in 20mnvb steel. 0.07-0.12% for vanadium and 0.001-0.005% for boron.

④ For high-quality steel, "a" shall be added at the end of the steel grade to distinguish it from general high-quality steel.

⑤ For alloy structural steel for special purpose, the steel grade is preceded by (or suffix) to represent the symbol of the purpose of the steel. For example, 30CrMnSi steel for riveting screw is represented as ml30crmnsi.

6. Low alloy high strength steel

① The representation method of steel grade is basically the same as that of alloy structural steel.

② For professional low alloy high strength steel, it shall be indicated at the end of the steel grade. For example, 16Mn steel, the special steel for bridge is "16Mnq", the special steel for automobile girder is "16MnL", and the special steel for pressure vessel is "16MnR".

7. Spring steel

According to the chemical composition, spring steel can be divided into carbon spring steel and alloy spring steel. The steel grade representation method of the former is basically the same as that of high-quality carbon structural steel, and the latter is basically the same as that of alloy structural steel.

8. Rolling bearing steel

① The steel grade is preceded by the letter "g", indicating the rolling bearing steel.

② The carbon content of high carbon chromium bearing steel grade is not marked, and the chromium content is expressed in thousands, such as GCr15. The representation method of steel grade of carburized bearing steel is basically the same as that of alloy structural steel.

9. Alloy tool steel and high speed tool steel

① When the average carbon content of alloy tool steel grade is ≥ 1.0%, the carbon content is not marked; When the average carbon content is less than 1.0%, it is expressed in thousands. For example, Cr12, CrWMn, 9SiCr, 3Cr2W8V.

② The expression method of alloy element content in steel is basically the same as that of alloy structural steel. However, for alloy tool steel grades with low chromium content, the chromium content is expressed in thousandths, and "0" is added before the number indicating the content, so as to distinguish it from the method of expressing the content of general elements in percentages. For example, cr06.

③ The steel grade of high-speed tool steel generally does not indicate the carbon content, but only a few percent of the average content of various alloy elements. For example, the steel grade of tungsten high speed steel is expressed as "W18Cr4V". The steel grade with the letter "C" indicates that its carbon content is higher than that of the general steel grade without the letter "C".

10. Stainless steel and heat resistant steel

① The carbon content in a steel grade is expressed in thousandths. For example, the average carbon content of "2Cr13" steel is 0.2%; If the carbon content in the steel is ≤ 0.03% or ≤ 0.08%, it is indicated by "00" and "0" respectively before the steel grade, such as 00Cr17Ni14Mo2, 0cr18 Ni9, etc.

② The main alloying elements in the steel are expressed in percentages, while titanium, niobium, zirconium, nitrogen, etc. are marked according to the representation of microalloyed elements in the above alloy structural steel.

11. Electrode steel

Its steel grade is preceded by the letter "H" to distinguish it from other steels. For example, stainless steel welding wire is "H2Cr13", which can be different from stainless steel "2Cr13".

12. Electrical silicon steel

① The steel grade consists of letters and numbers. The letter Dr at the beginning of the steel number indicates hot-rolled silicon steel for electrical purposes, DW indicates cold-rolled non oriented silicon steel for electrical purposes, and DQ indicates cold-rolled oriented silicon steel for electrical purposes.

② The number after the letter represents 100 times the iron loss value (w / kg).

③ The letter "g" at the end of the steel grade indicates that it is inspected at high frequency; If "g" is not added, it indicates that it is tested under the frequency of 50 cycles.

For example, the steel grade dw470 indicates that the * * * * iron loss per unit weight of cold-rolled non oriented silicon steel products for electrical purposes at 50 Hz frequency is 4.7w/kg.

13. Pure iron for electrician

① Its brand is composed of letters "DT" and numbers, "DT" represents pure iron for electrician, and numbers represent the sequence numbers of different brands, such as DT3.

② The letter added after the number indicates electromagnetic performance:  e - super grade, C - super, such as dt8a.
