Influencing factors of stainless steel

Whether stainless steel plate or heat-resistant steel plate, Austenitic steel plate has the best comprehensive performance, both sufficient strength, and excellent plasticity while hardness is not high, which is one of the reasons why they are widely used. Austenitic stainless steel is similar to most other metal materials, its tensile strength, yield strength and hardness increase with the decrease of temperature; The plasticity decreases with the decrease of temperature. Its tensile strength increases more evenly in the range of 15~80°C. More importantly, as the temperature decreases, the impact toughness decreases slowly, and there is no brittle transition temperature. Therefore, stainless steel can maintain sufficient plasticity and toughness at low temperatures. The heat resistance of stainless steel refers to the thermal stability of both oxidation resistance and gas medium corrosion resistance at high temperatures.
