Properties of stainless steel
Corrosion resistance
Stainless steel plate having a nickel-chromium alloy with an unstable 304 generally similar to resist corrosion. For a long time in the temperature range of the degree of chromium carbide heating may affect the alloy 321 and 347 in harsh corrosive media. Mainly used for high temperature applications, high-temperature applications require materials with strong anti-allergy activity, lower temperature to prevent inter-granular corrosion.430 stainless steel coil
High temperature oxidation resistance
Stainless steel has high temperature oxidation resistance, but the oxidation rate will be affected by exposure to environmental and product form factors such as inherent.303 Stainless Tubing
Physical properties
In addition to the overall heat transfer coefficient of thermal conductivity of a metal depends on the metal, but also depends on other factors. In most cases, film coefficient, descaling and surface condition of the metal. Stainless steel surface can be maintained clean, so it is better than a higher heat transfer coefficient of heat conductivity of the other metal. Liaocheng Suntory stainless steel offers eight excellent technical standard stainless steel plate stainless steel plate corrosion resistance, bending and welding parts toughness and punching workability of weld high strength stainless steel plate and its manufacturing method. Specifically, it 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 ℃, and then to 1 ℃ / s the cooling rate of the above heat treatment. Such organizations could be more than 12% volume fraction of martensite, 730MPa or more high strength, corrosion resistance and bending workability, excellent HAZ toughness of high strength stainless steel plate. Reuse containing Mo, B, etc., can significantly improve the performance of welded stamping parts.PPGI prepainted galvanized steel coils
