What is the difference between 05CuPCrNi grade steel and structural steel

05CUPCRNI 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.

Manganese is used to deoxidize and remove sulfur in steel when making steel. It is an beneficial element in 05CUPCRNI grade steel steel. Manganese has a strong ability to deoxidize and remove sulfur, it can eliminate or reduce the hot brittleness caused by oxygen and sulfur, and improve the strength and hardness of 05CUPCRNI grade steel steel.
