Product Introduction
Heat-resistant alloys are a special group of materials designed for high-temperature environments. These alloys contain a minimum of 12% chromium to form a protective chromium oxide layer at high temperatures. Additional elements such as carbon, nitrogen, nickel, silicon, and aluminum enhance their properties. Rare earth metals are also incorporated to improve oxide adherence.

Factors to Consider When Selecting Heat-Resistant Alloys

Oxidation Resistance: Heat-resistant alloys with at least 12% chromium can form an oxide layer that protects them at high temperatures. Beyond the oxidation threshold, they become porous and brittle.

Creep Strength: Creep is time-dependent deformation at elevated temperatures and constant stress. High creep strength alloys retain their shape, making them ideal for high-temperature applications.

Carburizing and Nitriding: These processes introduce carbon and nitrogen into the material's surface, enhancing wear resistance. Alloys with high nickel content are better suited for these environments.

Vacuum Processing: The process environment should be void of oxygen. Therefore, high temperature oxidation does not tend to be a concern.

Common Applications of Heat-Resistant Alloys:

Thermal Processing: Used for bar baskets, serpentine grids, radiant tubes, and retorts.

Chemical Processing: Used for flair tips, piping, steam methane reformers, and heat exchangers.

Galvanizing Lines: Used for their corrosion resistance.

Heat-resistant alloys are also used in a wide range of industries including:

Power Generation

Aerospace

Oil and Gas

Steel Manufacturing
