321 stainless steel coil is an austenitic stainless steel containing titanium, which has good high temperature performance, especially in high temperature environment. It shows good strength and stability. Specifically, the performance characteristics of 321 stainless steel coil in high temperature environment are as follows:
High temperature strength: 321 stainless steel coil has good high temperature strength, especially in the temperature range of 500°C to 900°C, it can still maintain strong tensile strength. The addition of titanium improves the strength of the material in high temperature environment, making it suitable for applications under high temperature conditions.
High temperature oxidation resistance: Due to the presence of titanium, 321 stainless steel has better oxidation resistance than 304 stainless steel. In a high temperature oxidation environment, titanium can form stable titanium carbides with carbon, thereby reducing carbide precipitation and improving the ability to resist high temperature oxidation.
Corrosion resistance: 321 stainless steel coil can still maintain good corrosion resistance at high temperature, especially in an environment with chloride or acidic medium. The addition of titanium can prevent stress corrosion cracking in a high temperature environment.
Stability: 321 stainless steel coil has good phase stability at high temperatures, especially in high temperature environments of about 800°C to 900°C. The addition of titanium reduces grain coarsening and material performance degradation caused by carbide precipitation.
Creep resistance: 321 stainless steel coil has good creep resistance at high temperatures and can maintain good shape and structural stability when working at high temperatures for a long time.
In general, 321 stainless steel coil exhibits strong strength, stability and corrosion resistance in high temperature environments, and is particularly suitable for some industrial fields that require high temperature tolerance and strong oxidation resistance, such as petrochemicals, heat exchangers, and aerospace.
