High Temperature / Heat Resisting Stainless Steel Pipes and Tubes




Heat Resisting Stainless Steel Seamless Tubing

These stainless steel have the good heat-resisting performance, is suitable in the steam environment or 55 0℃ and the above temperature. Mainly grade include: N04400, N06600, N06601, N06617, N06625, N06690, N08800, N08810, N08811, N08825, N08020, N08367, N08028, N06985, N06022, N10276

310S Stainless steel is a combination of good strength and corrosion resistance in temperature 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)
