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.

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 Stainlsss, Bar Products, Flat Rolled Products, and Piping Components.

Alloy Chemistry Data: Principal Design Features This alloy combines steeo resistance up to F C with high strength, good general corrosion resistance and ease of fabrication. It is austenitic in all conditions. 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.

For improved creep strength at high temperature, consider Alloysand 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.

Machinability Similar in characteristics to other austenitic heat resisting alloys. Positive feeds and slow speeds combined with abundant cutting fluid can minimize this alloys’ high tendency to work harden.

Forming This alloy can be readily sheared, formed and punched. Due to its high strength, however, expect to use higher forces to counteract its tendency to spring-back.

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

Preheating and post weld annealing are not required. Filler metal should be of similar composition for maximum weld integrity and properties. 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 by heating to F Cholding for minutes followed by air cooling. Hardening This alloy will not harden by thermal steeo.

Steel grade (UNS S – MA® – SS) in stainless steel

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

Applications include a wide variety of components requiring high strength at elevated temperatures. Similar in characteristics to other austenitic heat resisting alloys. This alloy can be readily sheared, formed and punched. Heat to F C and finish at F C. Stress relieve at F Cheld for minutes followed by air cooling.

This alloy will not harden by thermal treatment. Electrical Resistivity microhm-cm at 68 Deg F. Modulus of Elasticity Tension.
