Properties Of Stainless Steel Plates

The surface of stainless steel plate is smooth and clean, with high plasticity, toughness and mechanical strength, and it is resistant to corrosion of acids, alkaline gases, solutions and other media. It is an alloy steel that does not rust easily, but it is not absolutely rust-free.

 

1. Corrosion resistance

Stainless steel plates have a similar ability to resist general corrosion as unstable nichrome alloy 304. Prolonged heating in the temperature range of chromium carbide degrees may affect alloys 321 and 347 in harsh corrosive media. It is mainly used in high-temperature applications that require strong resistance to sensitization to prevent intergranular corrosion at lower temperatures.

 

2. High temperature oxidation resistance

Stainless steel sheets are resistant to oxidation at high temperatures, but the oxidation rate is affected by intrinsic factors such as the exposed environment and the form of the product.

 

3. Physical properties

The total heat transfer coefficient of a metal depends on other factors in addition to the thermal conductivity of the metal. In most cases, the heat dissipation coefficient of the film, the rust scale, and the surface condition of the metal. Stainless steel retains a clean surface, so it conducts heat better than other metals with higher thermal conductivity. Liaocheng Suntory Stainless Steel provides 8. The technical standards of stainless steel plates, stainless steel plates, corrosion resistance, bending performance and toughness of welded parts, as well as stamping performance of welded parts and their manufacturing methods. Specifically, the stainless steel plate containing C: 0.02% or less, N: 0.02% or less, Cr: 11% or more than 17%, and the appropriate content of Si, Mn, P, S, Al, Ni, and 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 is heated to 850~1250 °C, and then carried out at 1 °C/ Heat treatment of cooling rate above s. In this way, it can become a high-strength stainless steel plate with a structure containing more than 12% martensite with a volume fraction of more than 12%, high strength of more than 730MPa, corrosion resistance and bending processability, and excellent toughness in the welding heat-affected zone. Reuse of Mo, B, etc., can significantly improve the stamping performance of welded parts.

 

The flame of oxygen and gas cannot cut the stainless steel plate because the stainless steel is not easily oxidized.

5cm thick stainless steel plates are processed with special cutting tools, such as:

(1) Laser cutting machine with a large wattage

(2) Hydraulic saw

(3) Grinding discs

(4) Hand saw

(5) Wire Cutting machine.

(6) High-pressure waterjet cutting (professional waterjet cutting: Shanghai Xinwei)

(7) Plasma arc cutting
