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.

In comparison to carbon steel, stainless steels are tougher and tend to work harden rapidly. Principal Design Features This alloy combines oxidation resistance up to F C with high strength, good general corrosion resistance and ease of fabrication. Humble, Texas fax No forming should be performed in the range stajnless F C due to low ductility.

Due to its high strength, however, expect to use higher forces to counteract its tendency to spring-back. 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. 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. Hardening This alloy will not harden by thermal treatment.
Steel grade (UNS S – MA® – SS) in stainless steel
A wide variety of components requiring 523ma strength at elevated temperatures such as heat exchangers, kilns, stack dampers and oven components are common applications for MA. 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.
Modulus of Elasticity Tension. Heat to F C stianless finish at F C. Do not hold or soak at temperature due to problems associated with excessive grain growth. Stress relieve at F Cheld for minutes followed by air cooling.
Applications include a wide variety of components requiring high strength at elevated temperatures.
Stainless MA can be welded using conventional welding processes. It is austenitic in all conditions.
Filler metal should be of similar composition for maximum weld integrity and properties. Applications Applications include a wide variety of components requiring high strength at elevated temperatures. Stefl MA is a lean austenitic heat resistant alloy with high strength and outstanding oxidation resistance.
Positive feeds and slow speeds combined with abundant 253mx fluid can minimize this alloys’ high tendency to work harden. Electrical Resistivity microhm-cm at 68 Deg F.
This alloy combines oxidation resistance up to F C with high strength, good general corrosion resistance and ease of fabrication.
Stainless Steel 253 MA
Stainless steel MA is readily fabricated by standard commercial procedures. Forming This alloy can be readily sheared, formed and punched. Similar in characteristics to other austenitic heat resisting alloys. Alloy Chemistry Data: Among them are included radiant stainlesz tubes, heat exchangers, heat treating oven components, kilns, expansion bellows and stack dampers.
Annealing Stress relieve at F Cheld for minutes followed by air cooling. Megamex is a metal supplier for hastelloy, monel, inconel, stainless steel, carbon steel, metal fabrication, nickel alloys, and more. However, with positive feeds and slow speeds combined with abundant cutting fluid this alloys tendency to work harden may be minimized.
This alloy can be readily sheared, formed and punched. For improved creep strength at high temperature, consider Alloysand Full annealing is obtained by heating to F Cholding for minutes followed by air cooling.
This alloy will not harden by thermal treatment. Preheating and post weld annealing are not required. Machinability Similar in characteristics to other austenitic heat resisting alloys.
