ASTM A312 S30815 1.4835 253MA For Petrochemical
253MA / 1.4835 Stainless Steel Pipe is Rare Earth Metals (REM) and lean austenitic heat resistant alloy with high strength and outstanding oxidation resistance. 253MA maintains its heat resistant properties by advanced control of micro alloy additions.
The utilization of uncommon earth metals in blend with silicon surrenders better oxidation resistance than 2000°F. Nitrogen， carbon and a scattering of uncommon earth and soluble base metal oxides combine to give creep burst strength equivalent to the nickel base compounds.
Features of Stainless Steel 253 MA Pipe
• Very excellent protection from isothermal and， especially， cyclic oxidation
• Very excellent protection from burning gases
• Good primary soundness at high temperatures
• Good weldability
• Excellent oxidation protection from 2000°F
