Guangxi Nanning longitudinally welded pipes manufacturers | Nanning fast Exhibition steel pipe Nanning fast Exhibition large supply of Steel Pipe Co., Ltd. Nanning stainless steel plate | Stainless steel channel stainless steel welded pipe | Nanning spiral pipe, spiral welded pipe Nanning, Guangxi spiral pipe corrosion resistance of stainless steel plate bending performance and the toughness of the welded portions, as well as the punching excellent performance of the welded portion of high strength stainless steel plate and a method for producing the same. Specifically is containing C: 0.02% or less, N: 0.02% or less of Cr: more than 11% less than 17%, an appropriate content of Si, Mn, P, S, Al, Ni, and satisfy 12 ≤ Cr Mo 1.5Si ≤ 17,1 ≤ Ni 30 (CN) 0.5 (Mn Cu) ≤ 4, Cr 0.5 (Ni Cu) 3.3Mo ≥ 16.0,0.006 ≤ CN ≤ 0.030 of the stainless steel plate is heated to 850 to 1250 ° C, then carried 1 ° C / s or more cooling rate of the heat treatment. This can be a tissue containing more than 12% of the volume fraction of martensite, the high strength of more than 730MPa, corrosion resistance and bending properties, and excellent in the toughness of the weld heat affected zone of the high-strength stainless steel plate. Reuse containing Mo, B, etc., can significantly improve the punching workability of the welded portions.
