Property of stainless steel

Property of stainless steel

1. Corrosion resistance
The stainless steel sheet has the ability to withstand general corrosion similar to the unstable nichrome 304. Prolonged heating in the temperature range of chromium carbide may affect alloys 321 and 347 in harsh corrosive media. Mainly used in high temperature applications, high temperature applications require strong sensitization of materials to prevent intergranular corrosion at lower temperatures.
2. High temperature oxidation resistance
Stainless steel plates have high temperature oxidation resistance, but the oxidation rate is affected by inherent factors such as the exposed environment and product morphology.
3. Physical properties
The total heat transfer coefficient of the metal depends on other factors, in addition to the thermal conductivity of the metal. In most cases, the film’s heat dissipation coefficient, scale and metal surface condition. Stainless steel keeps the surface clean and tidy, so its heat transfer is better than other metals with higher thermal conductivity. Liaocheng Suntory Stainless Steel provides technical standards for stainless steel plates. High-strength stainless steel plates with excellent corrosion resistance, bending processability and weld site toughness, and excellent stamping performance at welded parts. Specifically, it contains C: 0.02% or less, N: 0.02% or less, Cr: 11% or more and less than 17%, and 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 is heated to 850 ~ 1250 ° C, and then carried out at 1 ° C / s The above heat treatment for cooling rate cooling. Thus, it can be a structure containing a martensite having a volume fraction of 12% or more, a high strength of 730 MPa or more, corrosion resistance, bending workability, and a high-strength stainless steel sheet excellent in weld heat-affected zone toughness. By using Mo, B, etc., the press working property of the welded portion can be remarkably improved.
