Astm 304 Stainless Steel Sheet Metal Cold Rolled 18 Gauge 1000mm

  The total heat transfer coefficient of a metal depends on other factors besides the thermal conductivity of the metal. In most cases, the heat dissipation coefficient of the film, the scale and the surface condition of the metal. Stainless steel can keep 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 workability, toughness of welded parts, and excellent stamping workability of welded parts and their manufacturing methods. Specifically, the content of C: 0.02% or less, N: 0.02% or less, Cr: 11% or more and less than 17%, appropriate content of Si, Mn, P, S, Al, Ni, and satisfies 12≤Cr Mo 1.5Si≤ 17. Stainless steel plates with 1≤Ni 30(CN) 0.5(Mn Cu)≤4, Cr 0.5(Ni Cu) 3.3Mo≥16.0, 0.006≤CN≤0.030 are heated to 850～1250℃, and then heated at 1℃/s The above cooling rate cooling heat treatment. In this way, it can become a high-strength stainless steel plate with a martensite content of more than 12% by volume, high strength of more than 730MPa, corrosion resistance and bending performance, and excellent toughness of the welded heat-affected zone. Reuse of Mo, B, etc., can significantly improve the stamping performance of the welded part.The flame of oxygen and gas cannot cut stainless steel plate because stainless steel is not easy to be oxidized.
