These stainless steel have the good heat-resisting performance which is suitable in the steam environment or 550°C and the above temperature.

Anticorrosion environment: The temperature may reach 800 °C.

Application: Boiler Industry.

310S Stainless steel is a combination of good strength and corrosion resistance in temperatures up to 2100oF (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℃ /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)

Available Grades: TP310S, TP309S, TP304H, TP321H, TP347H.
