The technical standards of stainless steel plate include corrosion resistance, bending processing performance and toughness of welding parts, as well as high-strength stainless steel plates with excellent stamping processing performance of welding parts and their manufacturing methods.
Specifically, Si, Mn, P, S, Al, Ni containing C: 0.02% or less, N: 0.02% or less, Cr: 11% or less than 17%, appropriate content Si, Mn, P, S, Al, Ni, and meeting 12≤Cr Mo 1.5Si≤17, 1≤Ni 30(C N) 0.5(Mn Cu)≤4, Cr 0.5 (Ni Cu) 3.3Mo≥16.0, 0.006≤C N≤0.030 stainless steel plate heated to 850~1250 °C, and then heated to 1 °C / Heat treatment of cooling above the cooling rate s. This can be a high-strength stainless steel plate with a structure containing more than 12% martensite by volume, high strength above 730MPa, corrosion resistance and bending processing performance, and excellent toughness in the welding heat-affected zone. The reuse of Mo, B, etc. can significantly improve the stamping performance of the welded part.
The flame of oxygen and gas cannot cut stainless steel plates because stainless steel is not easily oxidized.
5CM thick stainless steel plate to be processed with special cutting tools, such as:
(1) Laser cutting machine with large wattage,
(2) Hydraulic saw machine,
(3) grinding disc,
(4) Hand saws, and
(5) Wire Cutting machine.
