Heat Resisting Stainless Steel Seamless Tubes
These stainless steel have the good heat-resisting performance, is suitable in the steam environment or 550℃ and the above temperature.
Anticorrosion environment: The temperature may reach 800 ℃
Application: Boiler
310S Stainless steel is a combination of good strength and corrosion resistance in temperatures up to 2100oF (1149℃). 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℃.
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℃)
321H advantage an excellent resistance to intergranular corrosion following exposure to temperatures in the chromium carbide precipitation range from 800 to 1500°F (427℃ 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)
