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. Applications 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.
Stainless steel MA is readily fabricated by standard commercial procedures. Applications include a wide variety of components requiring high strength at elevated temperatures.
Filler metal should be of similar composition for maximum weld integrity and properties.

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, 253mz delivery times anywhere from 10 to 50 weeks depending on size and stainlss 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.
Hardening This alloy will not harden by thermal treatment.
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. Do not hold or soak at temperature due to problems associated with excessive grain growth. 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. Alloy Chemistry Data: Modulus of Elasticity Tension. Due to its high strength, however, expect to use higher forces to counteract its tendency to spring-back.
stailess Principal Design Features 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. Stainless MA can be welded using conventional welding processes. Positive feeds and slow speeds ssteel with abundant cutting fluid can minimize this alloys’ high tendency to work harden.

Filler metal should be of similar composition for maximum weld integrity and stainlesa. 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. However, with positive feeds and slow speeds combined with abundant cutting fluid this alloys tendency to work harden may be minimized.
For improved creep strength at high temperature, consider Alloysand Stress relieve at F Cheld for minutes followed by air cooling.
Full annealing is obtained by heating to F Cholding for minutes followed by air cooling. Stainless MA is a lean austenitic heat resistant alloy with high strength and outstanding stainleds resistance.
Steel grade (UNS S – MA® – SS) in stainless steel
Humble, Texas fax Preheating and post weld annealing are not required. In comparison to carbon steel, stainless steels are tougher and tend to work harden rapidly. Similar in characteristics to other austenitic heat resisting alloys. Forming This alloy can be readily sheared, formed and punched. Heat to F C and finish at F C. No forming should be performed in the range of F C due to low ductility.
