1.4835 is the EN numeric designation for this material. 1.4835, often recognized by its Outokumpu brand name of 253MA, is a heat-resistant austenitic chrome steel. It is designed to have related heat resistance to 310 however with higher creep power as a result of strengthening with nitrogen.

Thanks to the relatively excessive chromium content material and the addition of silicon and rare earth metals, a protecting oxide is easily formed on the floor of Sandvik 253 MA material. Carburization resistance is, due to this fact, good.

A stainless austenitic metal, designed primarily to be used at temperatures exceeding ~550° C. It has an elevated nitrogen content material and has been microalloyed with uncommon earth metals (REM) which provides good resistance to oxidation and relatively excessive creep energy values. The best suited temperature vary is ° C, because structural modifications when used between 600 and 850°C can result in reduced impact toughness at room temperature. It is non-magnetic in the annealed situation but may turn out to be barely magnetic because of chilly-working or welding. Compared with conventional austenitic stainless steels, Sandvik 253 MA has good resistance to cyanide melts and impartial salt melts and likewise to metallic melts, e.g. lead, at high temperatures.

• A stainless austenitic steel, designed primarily to be used at temperatures exceeding ~550° C.
• It is non-magnetic within the annealed condition but could turn into slightly magnetic as a result of cold-working or welding.
• The most suitable temperature range is ° C, as a result of structural changes when used between 600 and 850°C can result in low-impact toughness at room temperature.
• Compared with conventional austenitic stainless steels, Sandvik 253 MA has good resistance to cyanide melts and neutral salt melts and in addition to steel melts, e.g. lead, at high temperatures.
• It has an elevated nitrogen content and has been microalloyed with uncommon earth metals (REM) which supplies good resistance to oxidation and relatively excessive creep power values.

Sandvik 253 MA is not typically utilized in situations requiring nice resistance to wet corrosion. The steel is, nonetheless, barely more resistant than ASTM TP304 to emphasize corrosion cracking in chloride bearing aqueous solutions.

Similar Alloys

In common with all austenitic stainless steels, Sandvik 253MA has low thermal conductivity and excessive thermal enlargement. Welding plans should due to this fact be carefully chosen upfront, in order that distortions of the welded joint are minimized. If residual stresses are a concern, solution annealing can be carried out after welding. In alternately oxidizing and carburizing atmospheres and carburizing slags, Sandvik 253 MA is slightly extra susceptible to carburization than steels of upper chromium and/or nickel content. It’s actually 1.4828 with a better carbon content and an addition of noble earths.

In some cases, however, a differing composition may improve e.g. weldability or structural stability. Gas shielded welding has resulted in one of the best creep properties for welds. To facilitate the use of Therma 253 MA at the highest temperature vary, TIG, plasma, or MAG processes should be used.

Each week throughout the year, we’ll showcase one grade and illustrate the number of corrosion resistant, mechanical and physical properties which determine its suitability for a variety of purposes. Since most excessive-temperature materials are optimized with regard to strength and corrosion resistance at elevated temperatures, their resistance to electrochemical low-temperature corrosion could also be much less satisfactory. Components made from high-temperature material ought to subsequently be designed and operated in order that acid condensates usually are not shaped, or a minimum of so that any such condensates are drained away. The temperature above which design calculations are based on creep rupture energy as an alternative of Rp0.2 proof energy, can be learn off from Fig.
