The physical properties of 409 stainless steel plate

409 stainless steel plate has the ability and the instability of the Ni Cr alloy 304 similar to general corrosion. Long time heating in the 409 stainless steel plate  range of chromium carbide degree may influence the alloy 321 and 347 in the corrosive medium is bad in. Mainly used for high temperature applications, high temperature applications require materials with strong anti sensitization, to prevent corrosion at low temperature grain. High temperature oxidation resistance Stainless steel plate has high temperature stainless steel sheet  resistance, however, affect the oxidation rate will be affected by exposure to environmental and intrinsic factors of product form. The physical properties of 409 stainless steel plate The total heat transfer coefficient of thermal conductivity of metal addition depends on the metal, also depend on other factors. In most cases, surface film coefficient, rust and metal. 409 stainless steel plate can keep the surface clean, so the metal better heat transfer is higher than other thermal conductivity. Liaocheng Sandeli stainless steel strip  steel eight, stainless steel plate technology standard stainless steel plate corrosion resistance, bending properties and welding position toughness, and stamping properties of welded parts of high strength stainless steel plate and its manufacturing method. In particular, the C:0.02% containing the following below N:0.02%, Cr:11% is less than 17%, the proper contents of Si, Mn, P, S, Al, Ni, and Cr Mo meet 12 ≤ 1.5Si ≤ 17, 1 ≤ Ni 30 (C N) 0.5 (Mn Cu) ≤ 4, Cr 0.5 (Ni Cu) 3.3Mo more than 16 C, 0.006 ≤ N ≤ 0.030 stainless steel is heated to 850 to 1250 DEG C, and then by heat treatment at 1 ℃ /s above the cooling rate cooling. This can become a containing 12% volume fraction of martensite organization above, high strength, corrosion resistance and bending performance, more than 730MPa of welding HAZ toughness of high strength steel plate. Then with Mo, B and so on, can significantly improve the performance of welded parts stamping.
