Guangxi Wuzhou supply large diameter seamless steel pipe 15CrMoG alloy steel pipe manufacturer | steel pipe Nanning Nanning Xun exhibition Xun exhibition of Steel Pipe Co., Ltd. Nanning stainless steel | stainless steel channel | stainless steel pipe | the Nanning spiral, spiral welded pipe in Nanning, Guangxi spiral stainless steel large supply corrosion resistance, bending performance and toughness of the welded portion, as well as the welded portion of the stamping workability high-strength stainless steel plate and its manufacturing method. Specifically containing C: 0.02% or less, N: 0.02% or less, Cr: more than 11% less than 17%, the appropriate content of Si, Mn, P, S, Al, Ni, but satisfy 12 ≤ Cr Mo 1.5Si the ≤ 17,1 ≤ Ni 30 (CN) 0.5 (Mn, Cu) ≤ 4 Cr 0.5 (Ni Cu) 3.3Mo ≥ 16.0,0.006 ≤ the CN ≤ 0.030 stainless steel plate heated to 850 to 1250 ° C, and then to 1 ° C / s or more cooling rate of the heat treatment. This can become a martensite volume fraction of 12% or more organizations, more than 730MPa high strength, corrosion resistance and bending workability, and excellent in the toughness of the weld heat affected zone of high strength stainless steel plate. Recycling containing Mo, B, etc., can significantly improve the stamping performance of the welded portion.
