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.

Among them are included radiant heating tubes, heat exchangers, heat treating oven components, kilns, expansion bellows and stainlezs dampers. Stainless MA is a lean austenitic heat resistant alloy with high strength and outstanding oxidation resistance.

For improved creep strength at high temperature, consider Alloysand Stainless MA can be welded using conventional welding processes. Electrical Resistivity microhm-cm at 68 Deg F.

Alloy Chemistry Data: Hardening This alloy will not harden by thermal treatment. Annealing Stress relieve at F Cheld for minutes followed by air cooling. 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.

A wide variety of components requiring high strength at elevated stdel such as heat exchangers, kilns, stack dampers and oven components are common applications for MA.

Machinability Similar in characteristics to other austenitic heat resisting alloys. Modulus of Elasticity Tension. 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. Stainless steel MA is readily fabricated by standard commercial procedures. Nitrogen, carbon and a dispersion of rare earth and alkali metal oxides combine to provide creep rupture strength comparable to the nickel base alloys.

However, with positive feeds and slow speeds combined with abundant cutting fluid this alloys tendency to work harden may be minimized. Similar in characteristics to other austenitic heat resisting alloys. No forming should be performed in the range of F C due to low ductility.

Stainless Steel 253 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.

Stress relieve at F Cheld for minutes followed by air cooling. This alloy combines oxidation resistance up to F C with high strength, good general corrosion resistance and ease of fabrication. Due to its high strength, however, expect to use higher forces to counteract its tendency to spring-back.

Humble, Texas fax Forming This alloy can be readily sheared, formed and punched. Preheating and post weld annealing are not required. Principal Design Features 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. This alloy can be readily sheared, formed and punched.

Do not hold or soak at temperature due to problems associated with excessive grain growth. Heat to F C and finish at F C. In comparison to carbon steel, stainless steels are tougher and tend to work harden rapidly.

This alloy will not harden by thermal treatment. Positive feeds and slow speeds combined with 253na cutting fluid can minimize this alloys’ high tendency to work harden.

Filler metal should be of similar composition for maximum weld integrity and properties. Megamex is a metal supplier for hastelloy, monel, inconel, stainless steel, carbon steel, metal fabrication, nickel alloys, and more. Full annealing is obtained by heating to F Cholding for minutes followed by air cooling. Applications Applications include a 253am variety of components requiring high strength at elevated temperatures.
