321 stainless steel plate is better than 304 stainless steel plate in some aspects.
Both 321 stainless steel plate and 304 stainless steel plate belong to the 300 series stainless steel. They have little difference in corrosion resistance, but 321 stainless steel plate has obvious advantages in heat resistance and high temperature strength. 321 stainless steel plate contains titanium, which makes it perform better in high temperature environment.
Heat resistance: 321 stainless steel plate performs well in high temperature environment of 500-600 degrees, and is suitable for high temperature industrial and mining environment. Although 304 stainless steel also has good heat resistance, its performance at high temperature is not as good as 321 stainless steel12.
High temperature strength: 321 stainless steel plate has higher strength and creep resistance at high temperature, and is suitable for occasions that need to withstand high temperature and high stress.
Intergranular corrosion resistance: Because 321 stainless steel plate contains titanium, it can effectively control the formation of chromium carbide, thereby improving its ability to resist intergranular corrosion.
Application fields: 321 stainless steel plate is suitable for manufacturing wear-resistant acid containers, wear-resistant equipment linings, conveying pipelines, etc., especially in chemical, coal, petroleum and other industrial fields.
In summary, 321 stainless steel plate is superior to 304 stainless steel plate in high temperature strength, heat resistance and intergranular corrosion resistance, so it is more suitable for occasions that need to withstand high temperature and high stress.
