Technical Parameter

The heat resistance of 321 stainless steel medium thick plate is a significant attribute of this material. Let's delve into its heat resistance in detail:
1. High Temperature Stability: 321 stainless steel is designed to maintain its mechanical properties and structural integrity even when exposed to high temperatures. It exhibits excellent stability and does not undergo significant changes in its properties when subjected to elevated temperatures.
2. Operating Temperatures: 321 stainless steel is capable of withstanding prolonged exposure to temperatures up to 900°C (1652°F) without significant degradation. This temperature range is well-suited for many high-temperature applications across various industries.
3. Oxidation and Scaling Resistance: At elevated temperatures, 321 stainless steel forms a passive oxide layer on its surface. This oxide layer acts as a protective barrier, preventing oxidation and scaling of the underlying material. It enhances the material's resistance to high-temperature oxidation and helps maintain its integrity.
4. Resistance to Thermal Fatigue: Thermal fatigue is a phenomenon that occurs when a material undergoes cyclic heating and cooling. It can lead to cracks, deformation, or failure of the material. 321 stainless steel demonstrates good resistance to thermal fatigue, making it suitable for applications involving repeated exposure to high temperatures.
