Stainless steel plates have some properties such as corrosion resistance, high-temperature oxidation resistance, and physical properties. Below, we will introduce the properties of stainless steel plates from these three aspects to increase your understanding of them:
Corrosion resistance:
Stainless steel plates have similar resistance to general corrosion as unstable nickel chromium alloy 304. Long term heating within the temperature range of chromium carbide degree may affect the performance of alloys 321 and 347 in harsh corrosive media. Mainly used for high-temperature applications, which require materials to have strong resistance to sensitization to prevent intergranular corrosion at lower temperatures.
High temperature oxidation resistance:
Stainless steel plates have high-temperature oxidation resistance, but the oxidation rate is influenced by inherent factors such as exposure environment and product morphology.
Physical performance:
The total heat transfer coefficient of a metal depends on other factors besides its thermal conductivity. In most cases, the heat dissipation coefficient of the film layer, rust scale, and surface condition of the metal. Stainless steel can maintain a clean surface, so its heat transfer performance is better than other metals with higher thermal conductivity. Liaocheng Sandeli Stainless Steel provides eight technical standards for stainless steel plates. High strength stainless steel plates and their manufacturing methods have excellent corrosion resistance, bending processing performance, welding toughness, and stamping processing performance in the welding area. Specifically, stainless steel plates containing C: 0.02% or less, N: 0.02% or less, and Cr: 11% or more but less than 17%, with an appropriate content of Si, Mn, P, S, Al, Ni, and meeting the requirements of 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, are heated to 850-1250 ℃, and then subjected to heat treatment with a cooling rate of more than 1 ℃/s. In this way, it can become a high-strength stainless steel plate with martensite structure containing more than 12% volume fraction, high strength, corrosion resistance and bending processing performance above 730MPa, and excellent toughness of welding Heat-affected zone. Reusing materials containing Mo, B, etc. can significantly improve the stamping performance of welded parts.
The flame of oxygen and gas cannot cut stainless steel plates because stainless steel is not easily oxidized.
