The stainless steel plate has similar resistance to general corrosion as the unstable nichcr 304. Prolonged heating in the chrome-carbide degree temperature range may affect alloys 321 and 347 in harsh corrosive media. It is mainly used in high temperature applications, where the material is required to have strong sensitization resistance to prevent intergranular corrosion at lower temperatures.

High temperature oxidation resistance
Stainless steel plates have high temperature oxidation resistance, but the oxidation rate will be affected by exposure environment and product form and other inherent factors.
Physical property
The total heat transfer coefficient of a metal depends on other factors besides the thermal conductivity of the metal. In most cases, film heat dissipation factor, rust and metal surface condition. Stainless steel keeps the surface clean, so its heat transfer is better than other metals with higher thermal conductivity. Liaocheng Suntory stainless Steel provides eight, stainless steel plate technical standards stainless steel plate corrosion resistance, bending processing performance and toughness of welding parts, as well as welding parts of the stamping processing performance of excellent high strength stainless steel plate and its manufacturing method. Specifically, the contents of C: below 0.02%, N: below 0.02%, Cr: More than 11%, less than 17%, appropriate content of Si, Mn, P, S, Al, Ni, And meet 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 heating to 850 ~ 1250℃, Then the heat treatment is carried out at a cooling rate of more than 1℃/s. This can become a high strength stainless steel plate containing 12% volume fraction with martensite structure, 730MPa above high strength, corrosion resistance and bending performance, welding heat affected zone toughness excellent. Using Mo, B, etc., can significantly improve the stamping performance of welding parts.
Oxygen and gas flame can not cut stainless steel plate because stainless steel is not easy to be oxidized.

Steel pipes can also be divided into seamless steel pipes and welded steel pipes according to the production process. Seamless steel pipes are divided into hot-rolled and cold-rolled (drawn). Welded steel pipes are divided into straight seam welded steel pipes and spiral seam welded steel pipes.

Cause of 304 steel rust phenomenon
Chloride ions are found in many places, such as salt, sweat, sea water, sea wind, soil, and so on. In the presence of chloride ions, stainless steel corrodes quickly, even more than ordinary mild steel. Chloride ions form a complex with Fe in the alloying element, which reduces the positive potential of Fe, and then is oxidized by oxidizing agents who take away electrons [1]. So there are requirements for the use of stainless steel environment, and the need to wipe often, remove dust, keep clean and dry.
