Performance stainless steel plate

In addition to the overall heat transfer coefficient of thermal conductivity of metals depends on the metal, but also depends on other factors. In most cases, the film heat transfer coefficient or rust and surface condition of the metal. Stainless steel can keep the surface clean, so it is better than the thermal conductivity of the higher thermal conductivity of other metals. Liaocheng Suntory provide eight stainless steel, stainless steel plate excellent technical standard stainless steel plate corrosion resistance, bending workability and toughness of welded portion, and punching workability of weld high-strength 409 stainless steel plate and its manufacturing method. Specifically is to contain C: 0.02% or less, N: 0.02% or less, Cr: more than 11% but less than 17%, an appropriate content of Si, Mn, P, S, Al, Ni, and satisfies 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 stainless steel plate heated to 850 ~ 1250 ℃, then subjected to 1 ℃ / s the cooling rate of the above heat treatment. Such organizations can become more than 12% volume fraction of martensite, 730MPa above high strength, corrosion resistance and bending properties, HAZ toughness of high-strength stainless steel plate 304. Reuse containing Mo, B, etc., can significantly improve the punching workability weld.
