The influence of different surface finish of stainless steel plate
If the surface finish is different, even if the same heating, the surface of the rough and fine oxide is not the same. For example, in the place where the local defect is cleaned and in the place where it is not cleaned, the condition of the formation of oxide skin is different, which causes the surface of the workpiece to be uneven after pickling. In addition to the thermal conductivity of the metal, the total heat transfer coefficient depends on other factors. In most cases, the heat dissipation coefficient of the film layer, the rust and the surface condition of the metal. Stainless steel can keep the surface clean, so its heat transfer is better than other metals with higher thermal conductivity. The technical standard of stainless steel plate Stainless steel plate corrosion resistance, bending processing performance and toughness of the welding part, as well as the stamping processing performance of the welding part of the high strength stainless steel plate and its manufacturing method. Specifically, it contains C: less than 0.02%, N: less than 0.02%, Cr: More than 11% less than 17%, the appropriate content of Si, Mn, P, S, Al, Ni, And meet 12≤Cr Mo 1.5Si≤17, 1≤Ni...
