Heat Resistant Stainless Steel

These grades have excellent strength and creep resistance at high temperatures. They offer better resistance to oxidizing or reducing atmospheres depending on their chemistry balance.

Alloy Properties
Representative Alloys	HK40, HT
Applications	For high strength and corrosion resistance at temperatures above 1200 F
Limitations	Exposure to service conditions may degrade room temperature ductility and weldability; cannot be hardened
Typical Uses	Petrochemical refining, heat treatment furnaces
Machinability	Fair. Slow feeds and deep cuts recommended
Weldability	Shielded metal arc welding (SMAW) produces good results
Corrosion Resistance	Superior resistance to air, combustion gases, flue gases (reducing and oxidizing) and steam
