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.

Similar in characteristics to other austenitic heat 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.
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.
Heat to F C and finish at F C. Stainless steel MA is readily fabricated by standard commercial procedures. Forming This alloy can be readily sheared, formed and punched. Modulus of Elasticity Tension. No forming should be performed in the range of F Staknless due to low ductility.
RA 253 MA®
Megamex is a metal supplier for staibless, monel, inconel, stainless steel, carbon steel, metal fabrication, nickel alloys, and more. Do not hold or soak at temperature due to problems associated with excessive grain growth. However, with positive feeds and slow speeds combined with abundant cutting fluid this alloys tendency to work harden may be minimized. This alloy will not harden by thermal treatment. Among them are included radiant heating tubes, heat exchangers, heat treating oven components, kilns, expansion bellows and stack dampers.
Alloy Chemistry Data: Filler metal should be of similar composition for maximum weld integrity and properties.
Stainless MA, UNS S, Stainless MA – MEGA MEX
Nitrogen, carbon and a dispersion of rare earth and alkali metal oxides combine to provide creep rupture strength comparable to the nickel base alloys.
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. This alloy can be readily sheared, formed and punched. Positive feeds and slow speeds combined with abundant cutting fluid can minimize this alloys’ high tendency to work harden. Hardening This alloy will not harden stainleas thermal treatment. Stress relieve at F Cheld for minutes followed by air cooling.
Machinability Similar in characteristics to other austenitic heat resisting alloys.

Principal Design Features This alloy combines oxidation resistance up to F C with high strength, good general corrosion resistance and ease of fabrication. Stainless MA can be welded using conventional welding processes. 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 tseel and silicon with domestically available rare earth metals.
1.4835 (UNS S30815 – 253MA®* – SS2368)
Stainless MA is a lean austenitic heat resistant alloy with high strength and outstanding oxidation resistance. Humble, Texas fax In comparison to carbon steel, stainless steels are tougher and tend to work harden rapidly.
For improved creep strength 253m high temperature, consider Alloysand Annealing Stress relieve at F Cheld for minutes followed by air cooling. It is austenitic in all conditions.
This alloy combines oxidation resistance up to F C with high strength, good general corrosion resistance and ease of fabrication. Applications include a wide variety of components requiring high strength at elevated temperatures.
Electrical Resistivity microhm-cm at 68 Deg F. Preheating and post weld annealing are not required.
Due to its high strength, however, expect to use higher forces to counteract its tendency to spring-back.
