Physical properties of stainless steel plate

Release time:2021.08.11 Announcer: Hits:

The total heat transfer coefficient of a metal depends on other factors besides the thermal conductivity of the metal. In most cases, the heat dissipation coefficient of the film, the rust skin and the appearance of the metal. Stainless steel can adhere to the appearance of clean, so it is better than other higher thermal conductivity of metals. Liaocheng Sundeli stainless steel provides eight, stainless steel plate of the technical standard stainless steel plate corrosion resistance, twists and turns processing function and welding position tolerance, as well as welding position stamping processing function excellent high strength stainless steel plate and its production method.

Specifically, it will include C: less than 0.02%, N: less than 0.02%, Cr: Si, Mn, P, S, Al, Ni, And satisfied 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℃, The heat treatment is then carried out at a cooling rate above 1℃/s. This can become a high strength stainless steel plate containing 12% volume fraction with martensite arrangement, above 730MPa high strength, corrosion resistance and tortuous processing function, welding heat affected zone resistance excellent. Using Mo, B, etc., can significantly improve the stamping processing function of the welding position.

Oxygen and gas flame can not cut the stainless steel plate because stainless steel is not easy to be oxidized. 5CM thick stainless steel plate should be processed with special Cutting tools, such as: (1) Laser Cutting machine(Laser Cutting boot), (2) oil pressure saw, (3) disc grinding, (4) hand saw, (5)Wire Cutting machine(line Cutting boot).

Stainless steel plates have high temperature oxidation resistance, however, oxidation rate will be affected by the inherent factors such as exposure environment and product form.
