Description

Heat Resisting Stainless Steel Seamless Tubes
These stainless steel have the good heat-resisting performance, is suitable in the steam environment or **0℃ and the above temperature.
Anticorrosion environment: The temperature may reach **0 ℃

Application: Boiler
**0S Stainless steel is a combination of good strength and corrosion resistance in temperatures up to ***0oF (***9℃). Due to its relatively high chromium and nickel content it is superior in most environments to **4 or **9 stainless.
**9S High corrosion-resistant, chromium nickel grade with carbon limited to .*8 to reduce carbon precipitation during welding. Maximum Recommended Service Temperature Continuous ***0℃ /Intermittent  **0℃.
**4H the carbon content is controlled to a range of 0.***0.*8 to provide improved high temperature strength to parts exposed to temperatures above **0°F (**7℃)

**1H advantage an excellent resistance to intergranular corrosion following exposure to temperatures in the chromium carbide precipitation range from **0 to ***0°F (**7℃ to **6°C).
**7H in higher elevated temperature allowable stresses for these stabilized alloys for ASME Boiler and Pressure Vessel Code applications. The **1 and **7 alloys have maximum use temperatures of ***0°F (**6°C)
