Bar Products

Rolled Alloys is now inventorying RA 253 MA® round bar products in 5/8-3.5 inch diameter. RA 253 MA® is considered a lean austenitic heat-resistant alloy and obtains its heat-resistant properties by advanced control of micro-alloy additions. The use of rare earth metals in combination with silicon provides RA 253 MA® with properties superior to many nickel alloys while maintaining a low nickel content (11%). RA 253 MA® possesses superior oxidation resistance to 2000°F, high creep-rupture strength and excellent resistance to thermal shock.
