Stainless steel plate has an unstable nickel-chromium alloy and has the ability to resist general corrosion. Long-term 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 materials to have strong sensitization resistance to prevent intergranular corrosion at lower temperatures. 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.
