ASTM A573 Grade 70/A573 Gr.70 carbon manganese silicon steel plates are structural quality carbon steel plates just as A36 corten steel plate. ASTM A573 steel gardes are in three tensile strength ranges intended primarily for structural applications at atmospheric temperatures for which improved toughness is required.
The quality inspection department is responsible for the inspection management of raw materials and finished products, and the quality inspection and acceptance of products and raw materials. Strictly abide by the company's management system, conscientiously exercise the management power given by the company, and put an end to all ultra vires; be responsible for the inspection of all kinds of raw materials entering the company, and put forward quality problems and handling opinions.
Normalizing of steel plate is a heat treatment method that heats the A36 corten steel plate steel above the critical temperature so that all the steel is transformed into uniform austenite and then cooled naturally in the air.It can eliminate the network cementite of the hypereutectoid steel, for the hypoeutectoid steel normalization can refine the lattice, improve the comprehensive mechanical properties, for the parts with low requirements of normalization instead of annealing process is more economic.
20 to 26mm thick A36 corten steel plate product BBN steel supply: 20*3000*5000, 20.5*2370*7000, 21*1960*7950, 22*1800*8000, 22*1500*6000, 22*1500*6050, 22.5*1680*8450, 22*1300*4000, 22*2600*9000, 22*1800*9000, 22.5*2560*7150, 23.5*2560*7150, 25*1460*4000, 23*3000*11980, 23*2480*8450, 23*2650*6000, 24*1560*6200, 25.5*2330*8300, 23*3000*12000, 23.5*2080*8100, 23*2650*6550, 26*3010*8100.
