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.

1.4835 (UNS S30815 – 253MA®* – SS2368)
Annealing Stress relieve at F Cheld for minutes followed by air cooling. Positive feeds and slow speeds combined with abundant cutting fluid can minimize this alloys’ high tendency to work harden.
Nitrogen, carbon and a dispersion of rare earth and alkali metal oxides combine to provide creep rupture strength comparable to the nickel base alloys. Filler metal should be of similar composition for maximum weld integrity and properties. Stainless MA can be welded using conventional welding processes. Stress relieve at F Cheld 25ma minutes followed by air cooling.
Full annealing is obtained by heating to F Cholding for 253am followed by air cooling.
Do not hold or soak at temperature due to problems associated with excessive grain growth. This alloy combines oxidation resistance up to F C with high strength, good general corrosion resistance and ease of fabrication.
Similar in characteristics to other austenitic heat resisting alloys. Due to its high strength, however, expect to use higher forces to counteract its tendency to spring-back.
Alloy Chemistry Data: Modulus of Elasticity Tension. Forming This alloy can be readily sheared, formed and punched. Distributors will offer small 253mq buys while mills will generally only sell large quantities, with delivery times anywhere from 10 ateel 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.
Applications Applications include a wide variety of components requiring high strength at elevated temperatures.
Steel grade (UNS S – MA® – SS) in stainless steel
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.
For improved creep strength at high temperature, consider Alloys ssteel, and Megamex is a metal supplier for hastelloy, monel, inconel, stainless steel, carbon steel, metal fabrication, nickel alloys, and more. Electrical Resistivity microhm-cm at 68 Deg F. In comparison to carbon steel, stainless steels are tougher and tend to satinless harden rapidly. This alloy can be readily sheared, formed and punched.

Stainless MA is a lean austenitic heat resistant alloy with high strength and outstanding oxidation resistance. Among them are included radiant heating tubes, heat exchangers, heat treating oven stee, kilns, expansion bellows and stack dampers. No forming should be performed in the range of F C due to low ductility.
Humble, Texas fax Heat to F C and finish at F C. Filler metal should be of similar composition for maximum weld integrity and properties. Stainless steel MA is readily fabricated by standard commercial procedures. Applications include a wide variety of components requiring high strength at elevated temperatures. It is austenitic in all conditions.
Hardening This alloy will not harden by thermal treatment. This alloy will not harden by thermal treatment. Principal Design Features This alloy combines oxidation resistance up to F C with high strength, good stainlwss corrosion resistance and ease of fabrication. A wide variety sainless components requiring high strength at elevated temperatures such as heat exchangers, kilns, stack dampers and oven components are common applications for MA. However, with positive feeds and slow speeds combined with abundant cutting fluid this alloys tendency to work harden may be minimized.
Preheating and post weld annealing are not required. Machinability Similar in characteristics to other austenitic heat resisting alloys.
