420 stainless steel is a high-carbon martensitic stainless steel with high hardness and wear resistance. It is widely used in tools, molds and industrial components. However, its performance will change under high-temperature conditions, and attention needs to be paid during design and usage.
In a high-temperature environment, the hardness of 420 stainless steel may slightly decrease, and its wear resistance will be affected to some extent. At the same time, long-term exposure to temperatures above 400°C may cause the material to soften or result in changes to its microstructure. In contrast, 410 stainless steel maintains its hardness better under high temperatures, but its wear resistance is not as good as that of 420. The choice of material should be based on the usage temperature and load requirements in a comprehensive manner.
To ensure the stability of 420 stainless steel plates under high-temperature conditions, the following measures are recommended: First, select the appropriate thickness and specification based on temperature and load; second, conduct reasonable heat treatment to enhance the high-temperature resistance; third, perform surface strengthening or coating treatment on key components to improve wear resistance and oxidation resistance. Regular maintenance and inspection are also important means to extend the service life under high-temperature conditions.
