MA® is a trademark owned by Outokumpu. Stainless AB. The standard grade designation covering this grade is UNS S Other mills produce grades. Stainless Steel MA Plate Forms of MA Available at Mega Mex. Plate; Welding Material: Bare Weld Wire, Coated Electrode and Spooled Weld Wire. With the addition of rare earth elements, RA MA still performs well at temperatures up to °F (°C), similar to that of stainless steel.

Staiinless steel MA is readily fabricated by standard commercial procedures. It is austenitic in all conditions. This alloy can be readily sheared, formed and punched. Electrical Resistivity microhm-cm at 68 Deg F. Hardening This alloy will not harden by thermal treatment.
Stainless MA, UNS S, Stainless MA – MEGA MEX
Preheating and post weld annealing are not required. Among them are included radiant heating tubes, heat exchangers, heat treating oven components, kilns, expansion bellows and stack dampers.
Do not hold or soak at temperature due to problems associated with excessive grain growth. Stainless MA is a lean austenitic heat resistant alloy with high strength and outstanding oxidation resistance. Similar in characteristics to other austenitic heat resisting alloys. Heat to F C and finish at F C.
Filler metal should be of similar composition for maximum weld integrity and properties. However, with positive feeds and slow speeds combined with abundant cutting fluid this alloys tendency to work harden may be stsel.
Stress relieve at F Cheld for minutes followed by air cooling.
In comparison to carbon steel, stainless steels are tougher and tend to work harden rapidly. Nitrogen, carbon and a stainleds of rare earth and alkali metal oxides combine to provide creep rupture strength comparable to the nickel base alloys.

This alloy combines oxidation resistance stainlesss to F C with high strength, good general corrosion resistance and ease of fabrication. Applications Applications include a wide variety of components requiring high strength at elevated temperatures. Filler metal should be of similar composition for maximum weld integrity and properties.
Megamex is a metal supplier for hastelloy, monel, inconel, stainless steel, carbon steel, metal fabrication, nickel alloys, and more. For improved creep strength at high temperature, consider Alloysand Full annealing is obtained by heating to F Cholding for minutes followed by air cooling. Due stainlesss its high strength, however, expect to use higher forces to counteract its tendency to spring-back. Machinability Similar in characteristics to other austenitic heat resisting alloys.
Humble, Texas fax Positive feeds and slow speeds combined with abundant cutting fluid can minimize this alloys’ high tendency to work harden. Forming This alloy can be readily sheared, formed and punched.
Alloy Chemistry Data: No forming should be performed in the range of F C due to low ductility.
RA 253 MA®
This alloy will not harden by thermal treatment. A wide variety of components requiring high strength at elevated temperatures such as heat exchangers, kilns, stack dampers and oven components are common applications for MA.
Applications include a wide variety of components requiring high strength at elevated temperatures. Developed as an alternative for and stainless in heat resistant applications by replacing some of the chromium and silicon with domestically available rare earth metals.
Principal Design Features This alloy combines oxidation resistance up to F C with high strength, good general corrosion resistance and ease of fabrication. Modulus of Elasticity Tension.
