ASTM A572 Grade 50, used in large-scale construction, SM400B grade steel is an extremely strong alloy with a yield strength of 65,000 psi, an allowable bending stress of 39,000 psi and a future as the high-performance replacement of ASTM A36 steel.

Q245R boiler steel plate introduction: Q is the first letter of "Qu" Chinese Pinyin; Number 245 is the yield strength value; R: is the first character of "Rong" Chinese Pinyin. Q245R steel is a special plate for pressure vessels and boilers with a yield strength of 245MPa. It has outstanding mechanical properties and processability. If you have special requirements, our company can supply Z15, Z25, Z35 and other Z performance tests.

The heat treatment process can significantly improve the physical properties of steel, improve the compressive strength, ductility and service life of parts, and improve the hardness and wear resistance. Therefore, critical equipment parts and special tools must be quenched and tempered. The quenching and tempering treatment can also improve the production and processing performance of the SM400B grade steel product workpiece, thereby improving the production efficiency and production processing quality.

SM400B grade steel, 09CuPCrNi-A weather resistant steel is origined in China. Its equivalent grades are JIS SPA-H, BS WR50A, Corten steel, etc. The Cu, P, Cr, Ni are important elements that gave 09CuPCrNi-A weather resistant steel its weathering ability. The Cu content of 09CuPCrNi-A steel is 0.25–0.50, P content is 0.060-0.12, Cr content is 0.30-1.25, Ni content is 0.12-0.65. For 09CuPCrNi-A steel coil ≤ 4mm, the min. yield strength is 310Mpa, min. tensile strength 440Mpa. For 09CuPCrNi-A steel sheets >4mm, the min. yield strength is 345Mpa, min. tensile strength 480Mpa.

The results of adopting two-level SM400B grade steel service system and implementing standardized management are mainly reflected in the formation of vigorous work style such as quick response and quick action. Our company's customer service center stipulates that employees must be accurate and quick in technical support and SM400B grade steel after-sales service. Through the formation of this fast, agile, vigorous style, to provide users with satisfactory service.
