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.

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. This alloy will not harden by thermal treatment. In comparison to carbon steel, stainless steels are tougher and tend to work harden rapidly.

Stainless steel MA is readily fabricated by standard commercial procedures. Alloy Chemistry Stainkess It is austenitic in all conditions. For improved creep strength at high temperature, consider Alloysand Similar in characteristics 253mma other austenitic strel resisting alloys.

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 is 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. Among them are included radiant heating tubes, heat exchangers, heat treating oven components, kilns, expansion bellows and stack dampers. Preheating and post weld annealing are not required. Stress relieve at F Cheld for minutes followed by air cooling. Do not hold or soak at temperature due to problems associated with excessive grain growth.

This alloy can be readily sheared, formed and punched. No forming should be performed in the range of F C due to low ductility. Modulus of Elasticity Tension. 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. Filler metal staibless be of similar composition for maximum weld integrity and properties. Full annealing is obtained by heating to F Cholding for minutes followed by air cooling.

Applications Applications include a wide variety of components requiring high strength at elevated temperatures. Machinability Similar in characteristics to other austenitic heat resisting alloys.

This alloy combines oxidation resistance up to F C with high strength, good general corrosion resistance and ease of fabrication. Hardening This alloy will not harden by thermal treatment. Stainless MA can be welded using conventional welding processes.
