Distributors of Specialty Stainless Steel and High Grade Nickel Alloys.
Nickel-iron-chromium alloys with the same basic composition as INCOLOY® 800 but with much higher creep-rupture strength. The close control of the aluminum, titanium, and carbon contents in conjunction with a high-temperature anneal result in the higher strength. Incoloy® 800 H/HT is used in industrial furnaces, chemical and petrochemical processing, power plants for super-heater and re heater tubing, and heat-treating equipment.
