UNS S30815 is an austenitic chromium-nickel steel alloyed with nitrogen and rare earth metals. This material grade owns the following characteristic:

-High creep strength

-Very good resistance to isothermal and particularly, cyclic oxidation

-Good structural stability at high temperature

-Material could be used at temperature up to about 1150 grade

-Good weldability


S30815 has the excellent oxidation resistance, good resistance to carburization in constantly carburizing gas, and good resistance to salt and metal melts, at the high temperature.


Meanwhile, S30815 also owns the very high creep strength and structural stability. This material can very well replace the high nickel-alloy materials such as TP310S and Incoloy800H, or even Inconel600 in certain cases. It has come to be used extensively in the metallurgical, petrochemical and power industry.


This material could be used under the following conditions:

Tube used in the recuperator in the metallurgical industry

Tube used in the carbon black process gas cooler and air heater equipment

Tube used as the furnace tube

Tube used as thermocouple protection tube

Tube used as the burner component
