253MA STAINLESS STEEL PDF

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.

Stainless steel MA is readily fabricated by standard commercial procedures. Applications include a wide variety of components requiring high strength at elevated temperatures. Do not hold or soak at temperature due to problems associated with excessive grain growth. Annealing Stress relieve at F Cheld for minutes followed by air cooling. Full annealing is obtained stajnless heating to F Cholding for minutes followed by air cooling.

Stress relieve at F Cheld for minutes followed by air cooling. Stainless MA can be welded using conventional welding processes. This alloy will not harden by thermal treatment. Due to its high strength, however, expect to use higher forces to counteract its tendency to spring-back.

Filler metal should be of similar composition for maximum weld integrity and properties. Preheating and post weld annealing are not required. This alloy can be readily sheared, formed and punched.

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. Positive feeds and slow speeds combined with abundant cutting fluid can minimize this alloys’ high tendency to work harden. Heat to F C and finish at F C. Megamex is a metal supplier for hastelloy, monel, inconel, stainless steel, carbon steel, metal fabrication, nickel alloys, and more.

RA MA® – Rolled Alloys, Inc.

Principal Design Features This alloy combines oxidation resistance up to F C with high strength, satinless general corrosion resistance and stainlless of fabrication. 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.

Electrical Resistivity microhm-cm at 68 Deg F. Forming 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.

Humble, Texas fax Similar in characteristics to other austenitic heat resisting alloys. Nitrogen, carbon and a dispersion of rare earth and alkali eteel oxides combine to provide creep rupture strength comparable to the nickel base alloys.

In comparison to carbon steel, stainless steels are tougher and tend to work harden rapidly.

Modulus of Elasticity Tension. No forming should be performed in the range of F C due to low ductility.

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

Filler metal should be of similar composition for maximum weld integrity and properties. Among them are included radiant heating tubes, heat exchangers, heat treating oven components, kilns, expansion bellows and stack dampers. 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. Hardening This alloy will not harden by thermal treatment.

RA 253 MA®

Alloy Chemistry Data: This alloy combines oxidation resistance up to F C with high strength, good general corrosion resistance and ease of fabrication. It is austenitic in all conditions. Machinability Similar in characteristics to other austenitic heat resisting alloys. For improved creep strength at high temperature, consider Alloysand However, with positive feeds and slow speeds combined with abundant cutting fluid this alloys tendency to work harden may be minimized.

Applications Applications include a wide variety of components requiring high strength at elevated temperatures.
