316 stainless steel belongs to austenitic stainless steel. The key to high temperature resistance is the addition of 2.0% to 3.0% Mo element. The presence of this element enables 316 stainless steel to maintain stable chemical and mechanical properties under high-temperature environments.

The temperature resistance of 316 stainless steel pipes shows significant environmental dependence:
Oxidizing environment: It is recommended that the temperature for long-term continuous use should not exceed 800°C; otherwise, the oxide film may fail due to continuous oxidation.
Non-oxidizing environment: Under anaerobic or low-oxygen conditions, it can withstand high temperatures of around 1200°C, and even 1300°C for short-term intermittent use.
Load softening temperature: About 950°C, that is, the critical temperature at which the material begins to soften under stress conditions.

The range of high temperatures that 316 stainless steel can withstand is roughly 1200-1300 degrees, and it can be used under relatively harsh conditions. The reason why 316 stainless steel can withstand such high temperatures is that the addition of Mo element to 316 stainless steel greatly increases its corrosion resistance and high temperature strength.
