253MA is widely used in sintering equipment, blast furnace equipment, steel melting, melting furnace and continuous casting equipment, rolling mill (heating furnace), heat treatment furnace and accessories, mining equipment and cement production equipment. 253MA steel can be used in pressure bearing occasions up to 900 ℃ and non pressure bearing high temperature parts with working temperature up to 1150 ℃.
  • 253MA (UNS S30815, WNR 1.4835)
  • Ronsco
253MA (UNS S30815, WNR 1.4835)  is a heat resistant austenitic stainless steel designed for use requiring high creep strength and excellent corrosion resistance. The temperature range is 850 ~ 1100 ℃.

The chemical composition of 253MA is balanced, which makes the steel have the most suitable inductive function in the temperature range of 850 ℃ - 1100 ℃. It has high oxidation resistance, the temperature of starting oxide skin is as high as 1150 ℃; it has very high creep deformation resistance and creep fracture strength; it has excellent high temperature corrosion resistance and balance brush corrosion resistance in most gas medium; it has high compliance strength at high temperature And tensile strength; excellent formability and weldability, and machinability to meet the requirements.

In addition to chromium and nickel, 253MA stainless steel is also rich in rare earth metals, and its oxidation resistance is improved obviously. Nitrogen was added to improve the creep function and make the steel completely austenitic. Although the contents of chromium and nickel are relatively low, this stainless steel in many cases has the same high temperature characteristics as high alloyed alloy steel and nickel base alloy.

253MA Genenal Introduction
253 MA is a stainless steel with excellent oxidation and creep resistance in cyclic conditions that is best employed in temperatures up to 1150 °C/2100 °F. There is a slight susceptibility to embrittlement during continuous operation at 600–850 °C/1110–1560 °F.
