420 Stainless Steel Plate Description

420 stainless steel is a medium carbon (0.15% to 0.40%) chromium stainless steel. Typically, it exhibits limited heat resistance and is more suitable for low-temperature working environments, with a maximum operating temperature of around 650°C. To enhance the heat resistance of 420 stainless steel, heat treatment processes such as solution treatment, quenching, and annealing can be employed. These treatments can improve the material’s grain boundary structure and grain size, thereby enhancing its heat resistance. However, it’s important to note that the heat resistance of 420 stainless steel is lower than that of other heat-resistant stainless steels, making it more suitable for use in low-temperature environments. For high-temperature applications, it is advisable to select stainless steel materials with superior heat resistance.
