Key Properties

Why High Temperature Alloys?

High Temperature Strength

Maintains mechanical properties at temperatures exceeding 1000°C with excellent creep resistance.

Oxidation Resistance

Protective oxide layer formation prevents scaling and metal loss in oxidizing atmospheres.

Carburization Resistance

High nickel content provides resistance to carbon pickup in carburizing environments.

Creep Resistance

Resists deformation under sustained loads at elevated temperatures for extended service life.

Thermal Fatigue Resistance

Withstands repeated heating and cooling cycles without cracking or warping.

Sulfidation Resistance

Selected grades resist attack from sulfur-containing gases and environments.
