Boiler Plate

Vessel plate classification

Q345R is a large category of steel plates - container plate

Designation: Q345R 16MnR 16Mng.

For example: Q345R. Q - the first letter of "Qu" Chinese pinyin. 345 - yield strength value. R: "Rong" is the first letter of Chinese pinyin.

According to the new classification of GB 713-2008 steel plates for boilers and pressure vessels implemented on September 1, 2008, 16Mng, 16MnR and 19mng are combined into Q345R. Q345R is an ordinary low alloy steel, which is commonly used for boilers and pressure vessels. The delivery status is divided into hot rolling or normalizing. It is a low alloy steel. The properties are similar to those of Q345 (16Mn) (the yield strength of 16mm steel plate is greater than 345mpa), the tensile strength is between (510-640), the elongation is greater than 21%, and the zero V-type impact energy is greater than 34j. Q345R process reference standard GB713-2008.

Q345R steel is a special plate for pressure vessel with yield strength of 340mpa. It has good comprehensive mechanical and process properties. The content of phosphorus and sulfur is slightly lower than that of Q345 (16Mn) steel, a low-alloy high-strength steel plate. In addition to improving the tensile strength and elongation compared with Q345 (16Mn) steel, it is also required to ensure the impact toughness. It is the most widely used and used special steel plate for pressure vessels in China.

It is a large category of steel plates - boiler plate. Brand representation method: similar to Q345R, the brand of low-alloy high-strength structural steel is represented by the first letter of Chinese Pinyin of yield strength value "Qu" and pressure vessel "Rong". For example: Q245R. Q - the first letter of "Qu" Chinese pinyin. 245 - yield strength value. R: "Rong" is the first letter of Chinese pinyin.

It is mainly used as pressure vessel. According to different purposes, temperature and corrosion resistance, the material of vessel plate should be selected is also different.

Delivery status: hot rolling, controlled rolling and normalizing. Flaw detection shall be added upon agreement between the supplier and the demander.

Such as: 20R, 16MnR, 14Cr1MoR, 15CrMoR, 09MnNiDR, 12cr2mo1r, 16MnR (HIC), 20R (HIC), etc

The above are commonly used brands in China; There are also foreign brands, such as sa516gr60, SA516Gr70, etc.

Niobium, vanadium and titanium can be added to Q245R steel, and their contents shall be filled in the quality certificate. The total content of the above three elements shall not be greater than 0.050% respectively
