Lamellar tear resistant steel is what we call Z-direction steel, which is mainly used as the key material for the complex stress state of the steel plate of some important welded components such as offshore oil production platform, shipbuilding, boiler and pressure vessel. Z - direction steel is a special smelted and treated steel on the basis of structural steel. The sulfur content of Z-direction steel is one fifth of that of ordinary steel, and the cross-section shrinkage rate is more than 15%.
The mechanical properties of steel plates along the thickness direction are called z - direction properties. The z - direction performance of the steel plate can be obtained by tensile test of the sample, and is generally measured by the reduction of section. In order to ensure the safety performance of Z steel, before leaving the factory must be checked with ultrasonic, only qualified after the factory, and sent to the hands of the user. Z direction steel has strict requirements on purity of molten steel, quality of billet and microstructure of steel plate, as well as good flaw detection performance. If in the production of Z to steel, ultrasonic inspection phenomenon, can optimize the smelting process, strict control of molten steel, so that the quality of molten steel is improved, so as to greatly improve the qualified rate of Z to steel. There are many manufacturers engaged in the production and supply of Z to steel on the market now. Although they can meet the needs of the majority of users for Z to steel, the quality of Z to steel is also uneven. If you want to buy qualified Z to steel, you still need to carefully compare and choose when buying. If you do not know how to choose z to steel, do not know how to identify the quality of Z to steel, you can directly contact our company. Z steel supplied by our company is qualified in quality and reasonable in price, which will meet your demand for Z steel.
