316 stainless steel bolts have good air oxidation resistance in continuous service up to 871°C and up to 927 °C (1700F°).Continuous use is not recommended within the range of 427° c-857 °C, but has excellent heat resistance for continuous use outside this temperature range.The carbide dissolution resistance of 316L stainless steel is stronger than that of 316 stainless steel and can be used in the temperature range.
