Regardless of whether stainless steel plates or heat-resistant steel plates, austenitic steel plates have the best overall performance. They have sufficient strength, excellent plasticity and low hardness. This 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 as the temperature decreases; the plasticity decreases as the temperature decreases. Its tensile strength increases evenly within the temperature range of 15~80°C. More importantly, as the temperature decreases, its 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 resistance to oxidation or gas medium corrosion at high temperatures, that is, thermal stability.
