253MA(1.4835, UNS S30815) Stainless Steel Seamless Pipe

253MA is based on alloy 1.4828, which is microalloyed by increasing nitrogen content and adding rare earth elements. It has good oxidation resistance, high temperature corrosion resistance and high temperature mechanical strength. The optimum temperature range is 850-1100 ℃. If it is used at 600-850 ℃, the impact toughness at room temperature will be reduced due to structural changes. 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, mineral deposit equipment and cement production equipment, etc. 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) is a kind of heat resistant stainless steel developed on the basis of 21cr-11ni stainless steel by alloying rare earth elements CE and CN. Generally, 253MA is austenite. Due to the interaction of rare earth elements and silicon, the material still has good oxidation resistance at 1150 ℃. 

However, the existence of cyanide, carbon, rare earth elements and alkali metal oxides makes 253MA have the same stress rupture strength as Ni based alloy. Therefore, 253MA can replace the expensive nickel base alloy, and can be widely used in high temperature parts with working temperature above 900 ℃ and pressure bearing occasions below 900 ℃.

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.
