These stainless steel have the good heat-resisting performance, is suitable in the steam environment or 550°C and the above temperature.
310S Stainless steel is a combination of good strength and corrosion resistance in temperature up to 2100°F (1149°C). Due to its relatively high chromium and nickel content it is superior in most environments to 304 or 309 stainless.
309S High
corrosion-resistant, chromium nickel grade with carbon limited to .08 to reduce carbon precipitation during welding. Maximum Recommended Service Temperature Continuous 1100°C /Intermittent 980°C
304H the carbon content is controlled to a range of 0.04-0.08 to provide improved high temperature strength to parts exposed to temperatures above 800°F (427°C)
321H advantage an excellent resistance to
intergranular corrosion following exposure to temperatures in the chromium carbide precipitation range from 800 to 1500°F (427°C to 816°C).
347H in higher elevated temperature allowable stresses for these stabilized alloys for ASME
Boiler and Pressure Vessel Code applications. The 321 and 347 alloys have maximum use temperatures of 1500°F (816°C)
