Performance
A 25%Cr-20%Ni high-alloy austenitic that resists oxidation up to about 1150℃, among the strongest conventional stainless grades for heat and carburization resistance.
Use cases
High-temperature furnace tubes, heat-treat fixtures, petrochemical cracking furnaces, incinerators, glass/ceramic kiln furniture.
Characteristics
Good high-temperature strength and microstructural stability, but high thermal expansion and low conductivity demand care against thermal fatigue.
