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.

Machinability Similar in characteristics to other austenitic heat resisting alloys.

Stainless Steel 253 MA

Applications include a wide variety of components requiring high strength at elevated temperatures. Stainless MA is a lean 253mw heat resistant alloy with high strength and outstanding oxidation resistance.

This alloy combines oxidation resistance up to F C with high strength, good general corrosion resistance and ease of fabrication.

In comparison to carbon steel, stainless steels are tougher and tend to work harden rapidly. Annealing Stress relieve at Stainlesa Cheld for minutes followed by air cooling.

This alloy can be readily sheared, formed and punched. 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.

No forming should be performed in the range of F C due to low ductility. For improved creep strength at high temperature, consider Alloysand 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 stainlese of fabrication. Applications Applications include a wide variety of components requiring high strength at elevated temperatures.

MA® – Stainless Steels Available From NeoNickel

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 Stainlees. Full annealing is obtained by heating to F Cholding for minutes followed by air cooling.

Stress relieve at F Cheld for minutes followed by air cooling. Heat to F C and finish at F C. Humble, Texas fax Alloy Chemistry Data: This alloy will not harden by thermal treatment. However, with stianless feeds and slow speeds combined with abundant cutting fluid this alloys tendency to work harden may be minimized.

Hardening This alloy will not harden by thermal treatment. Forming This dteel can be readily sheared, formed and punched. Modulus of Elasticity Tension. Filler metal should be of similar composition for maximum weld integrity and properties. Stainless steel MA is readily fabricated by standard commercial procedures.

Do not hold or soak at temperature due to problems associated with excessive grain growth.

1.4835 (UNS S30815 – 253MA®* – SS2368)

Among them are included radiant heating tubes, heat exchangers, heat treating oven components, kilns, expansion bellows and stack dampers. Due to its high strength, however, expect to use higher forces to counteract its tendency to spring-back.

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.

Stainless MA can be welded using conventional welding processes. Positive feeds and slow speeds combined with abundant cutting fluid can minimize this alloys’ high tendency to work harden. Preheating and post weld annealing are not required. 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.
