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.

This alloy will not harden by thermal treatment. Full annealing is obtained by heating to F Cholding for minutes followed by air cooling. Alloy Chemistry Data: Annealing Stress relieve at F Cheld for minutes followed by air cooling. Modulus of Elasticity Tension. Stainless steel MA is readily fabricated by standard commercial procedures.
For improved creep strength at high temperature, consider Alloysand It is austenitic in all conditions. Heat to F C and finish at F C. This alloy can be readily sheared, formed and punched. Electrical Resistivity microhm-cm at 68 Deg F.

Similar in characteristics to other austenitic heat resisting alloys. A ssteel variety of components requiring high strength at elevated temperatures such as heat exchangers, kilns, stack dampers and oven components are common applications for MA.
Positive feeds and slow speeds combined with abundant cutting fluid can minimize this alloys’ high tendency to work harden. No forming should be performed in the range of F C due to low ductility. Hardening This alloy will not harden by thermal treatment. Humble, Texas fax Preheating and post weld annealing are not required.
Distributors will offer small quantity buys while mills will generally only sell large quantities, with delivery sgeel anywhere from 10 to 50 weeks depending on size and form required This material is stocked primarily in Tubular Products by 3 distributors but is also available to a lesser extent in Wire Products, Bar Products, Flat Rolled Products, and Piping Components.
Filler metal should be of similar composition for maximum weld integrity and properties.
Nitrogen, carbon and a dispersion of rare earth and alkali metal oxides combine to provide creep rupture strength comparable to the nickel base alloys. This alloy combines oxidation resistance up to F C with high strength, good general corrosion resistance and ease of fabrication.
Machinability Similar in characteristics to other austenitic heat resisting alloys. Applications include a wide variety of components requiring high strength at elevated temperatures.
However, with positive feeds and slow speeds combined with abundant cutting fluid this alloys tendency to work harden may be minimized. Megamex is a metal supplier for hastelloy, monel, inconel, stainless steel, carbon steel, metal fabrication, nickel alloys, and more.
RA 253 MA®
Filler metal should be of similar composition for maximum weld integrity and properties. Stress relieve at F Cheld for minutes followed by air cooling.
Forming This alloy can be readily sheared, formed and stainlexs. Among them are included radiant heating tubes, heat exchangers, heat treating oven components, kilns, expansion bellows and stack dampers. Due to its high strength, however, expect to use higher forces to counteract its tendency to spring-back.
Stainless MA can be welded using conventional welding processes. In comparison to carbon steel, stainless steels are tougher and tend to work harden rapidly.
Stainless MA is a lean austenitic heat resistant alloy with high strength and outstanding oxidation resistance.
Do not hold or soak at temperature due to problems associated with excessive grain growth.
RA MA® – Rolled Alloys, Inc.
Principal Design Features This alloy combines oxidation resistance up 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. Developed as an alternative for and stainlexs in heat resistant applications by replacing some of the chromium and silicon with domestically available rare earth metals.
