RA253MA04533

• A lean austenitic heat resistant alloy with high strength and outstanding oxidation resistance.
• It offers an excellent combination of creep strength along with excellent resistance to oxidation, sulfidation, and erosion at high temperatures in an alloy containing just 11% nickel.
• Obtains its heat resistant properties by tight control of micro alloy additions.
• The use of cerium in combination with silicon results in superior oxidation resistance to 2000°F (1093°C).
• Very economical compared to most heat resistant alloys.
