What is UNS S30815 Heat Resistance Stainless Steel?
Grade UNS S30815 is a lean heat-resistant austenitic stainless steel developed for applications requiring high creep strength and good corrosion resistance.
Grade UNS S30815 stainless steel, also referred to as the W.Nr. 1.4835 alloy.
Grade UNS S30815 contains fairly low nickel content, which gives it some advantage in reducing sulphide atmospheres when compared to high nickel alloys and to grade 310S.
The inclusion of high silicon, nitrogen and cerium contents gives the steel good oxide stability, high elevated temperature strength and excellent resistance to sigma phase precipitation.
Grade UNS S30815 stainless steel is available in all standard mill forms including pipe, rod, bar, plate, sheet, strip and foil products.
