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.

Machinability Similar in characteristics to other austenitic heat resisting alloys.
Applications Applications include a wide variety of components requiring high strength at elevated temperatures. Positive feeds and slow speeds combined with abundant cutting fluid can minimize this alloys’ high tendency to work harden.
RA 253 MA®
Do not hold or soak at temperature due to problems associated with excessive grain growth. Forming This alloy can be readily sheared, formed and punched. Modulus of Elasticity Tension. It is austenitic in all conditions.
Stainless MA, UNS S, Stainless MA – MEGA MEX
This alloy can be readily sheared, formed and punched. Similar in characteristics to other austenitic heat resisting alloys. Electrical Resistivity microhm-cm at 68 Deg F.
Stainless MA can be welded using conventional welding processes. Annealing Stress relieve at F Cheld for minutes followed by air cooling. Distributors will offer small quantity buys while mills will generally only sell large quantities, with delivery times anywhere from 10 to 50 weeks depending on size and form required This material is stocked primarily in Tubular Products by 3 distributors but ateel also available to a lesser extent in Wire Products, Bar Products, Flat Rolled Products, and Piping Components.
Due to its high strength, however, expect to use higher forces to counteract its tendency to spring-back. Nitrogen, carbon and a dispersion of rare earth and alkali metal oxides combine to provide creep rupture strength comparable to the nickel base 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 minimized. Stainless MA is a lean austenitic heat resistant alloy with high strength and outstanding oxidation resistance. Applications include a wide variety of components requiring high strength at elevated temperatures. Among them are included radiant heating tubes, heat exchangers, heat treating oven components, kilns, expansion bellows and stack dampers.
For improved creep strength at high temperature, consider Alloysand 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. Stress relieve at F Cheld for stfel followed by air cooling.
Steel grade (UNS S – MA® – SS) in stainless steel
Stainless steel MA is readily fabricated by standard commercial procedures. Alloy Chemistry Data: Preheating and post weld annealing are not required. Humble, Texas fax In comparison to carbon steel, stainless steels are tougher and tend to work harden rapidly. No forming should be performed in the range of F C due to low ductility.

Megamex is a metal supplier for hastelloy, monel, inconel, stainless steel, carbon steel, metal fabrication, nickel alloys, and more. Filler metal should be of similar composition for maximum weld integrity and properties. 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 stainlesss oxidation resistance up to F C with high strength, good general corrosion resistance and ease of fabrication.
This alloy combines oxidation resistance up staijless F C with high strength, good general corrosion resistance and ease of fabrication.
Hardening This alloy will not harden by thermal treatment. This alloy will not harden by thermal treatment. Full annealing is obtained by heating to F Cholding for minutes followed by air cooling.
