321 Stainless Steel: High-Temperature Stability

321 stainless steel is a stainless steel specifically designed for high-temperature environments. Through titanium stabilization, it maintains structural integrity and resists corrosion under extreme temperatures. This material is highly reliable in high-temperature applications, such as furnaces, engines, or heat exchangers.

Significance of High-Temperature Stability
Materials used in high-temperature environments (e.g., furnaces, engines, or heat exchangers) must retain their mechanical properties under prolonged heat exposure. 321 stainless steel excels in this regard: its titanium stabilization prevents carbide precipitation and intergranular corrosion, even at temperatures up to 900°C.

Key Properties of 321 Stainless Steel:

Heat Resistance: Suitable for continuous service at temperatures up to 900°C.
Oxidation Resistance: Performs well in oxidizing environments due to its protective chromium oxide layer.
Titanium Stabilization: Enhances strength and prevents carbide formation at elevated temperatures.
