Pressure cooker is also called pressure cooker, pressure cooker, is a kind of kitchen utensil. The pressure cooker uses the physical phenomenon that the boiling point of the liquid will increase at a higher pressure so that the water can reach a higher temperature without boiling, so as to speed up the efficiency of stewing food. It can be used to heat the food being steamed to above 100 degree .

Cast stainless steel can generally be divided into three categories, namely, medium and high-strength martensitic stainless steel for engineering structures, corrosion-resistant stainless steel, and heat-resistant stainless steel. Cast stainless steel medium and high-strength martensitic stainless steels include martensitic stainless steel and precipitation hardening stainless steel. material) has good corrosion resistance. The metallographic structure is low-carbon lath martensite.

Cast stainless steel Corrosion-resistant stainless steel, also known as stainless acid-resistant steel, mainly assesses its corrosion resistance. It can be divided into two categories: chromium stainless steel and nickel-chromium stainless steel. The main factors affecting the corrosion resistance of stainless steel are the carbon content and the amount of precipitated carbides. , so carbon is generally very low, usually less than 0.08 percent .

Cast stainless steel heat-resistant stainless steel For heat-resistant stainless steel, because the high-temperature mechanical properties depend on the stable carbide precipitates in the steel, the carbon content is higher than that of corrosion-resistant steel, about 0.20 percent or more. The heat-resistant temperature of high-alloy heat-resistant steel castings can reach above 650 degree .
