Stainless steel plate performance: corrosion resistance

Stainless steel has general corrosion resistance similar to the unstable nickel-chromium alloy 304. Prolonged heating in the temperature range of chromium carbide degrees may affect alloys 321 and 347 in harsh corrosive media. Mainly used in high temperature applications, the material is required to have strong resistance to sensitization to prevent intergranular corrosion at lower temperatures.

high temperature oxidation resistance

Stainless steel plates are resistant to high temperature oxidation, but the oxidation rate will be affected by inherent factors such as exposure environment and product shape.

physical properties

The overall heat transfer coefficient of a metal depends on factors other than the thermal conductivity of the metal. In most cases, the heat dissipation coefficient of the film, the oxide scale and the surface condition of the metal. Stainless steel keeps the surface clean, so it conducts heat better than other metals with higher thermal conductivity. Liaocheng Suntory Stainless Steel Regulations 8. Technical Standards for Stainless Steel Plates High-strength stainless steel plates with excellent corrosion resistance, bending workability, toughness of welded parts, and stamping workability of welded parts and their manufacturing methods. Specifically, containing C: 0.02% or less, N: 0.02% or less, Cr: 11% or more and less than 17%, appropriately containing Si, Mn, P, S, Al, Ni, and satisfying 12≤Cr Mo 1.5Si≤17 . Heat the stainless steel plate with 1≤Ni 30(CN) 0.5(Mn Cu)≤4, Cr 0.5(Ni Cu) 3.3Mo≥16.0, 0.006≤CN≤0.030 to 850～1250℃, and then heat to 1℃/s or more Cooling rate cooling heat treatment. In this way, it can become a high-strength stainless steel plate, whose structure contains more than 12% martensite volume, has a high strength of more than 730MPa, corrosion resistance and bending performance, and has excellent toughness in the welding heat-affected zone. The repeated use of Mo, B, etc. can significantly improve the stamping performance of welded parts.

Oxygen and gas flames cannot cut stainless steel because stainless steel is not easily oxidized.
