High-temperature Tubes
Sandvik 253 MA is often preferred as a substitute of stainless chromium steels which have inadequate creep energy and structural stability. Furthermore, Sandvik 253 MA can very properly take the place of higher alloyed supplies such as 25Cr/20Ni steels and Alloy 800H, or even Alloy 600 in certain instances. Sandvik 253 MA has very excessive resistance to oxidation, particularly under cyclic circumstances, because of the addition of reactive components, corresponding to cerium (Ce). The high mechanical energy of Sandvik 253 MA permits for thinner tube wall constructions compared with utilizing materials of the ASTM 310 sort. Despite the fabric’s excessive power, ductility just isn’t reduced, and good formability is maintained.
253MA is a lean warmth-resistant austenitic stainless-steel developed for purposes requiring high creep strength and good corrosion resistance. Its balanced chemical compositions give this steel the optimum general efficiency underneath temperature range of 850 °C-1100 °C, and intensely excessive oxidation resistance. It produces oxide skin when temperature achieves up to 1150°C. Compared with standard austenitic stainless steels, Sandvik 253 MA has good resistance to cyanide melts and neutral salt melts and also to metal melts, e.g. lead, at excessive temperatures. Its resistance to metallic melts is to a great extent determined by the oxygen content material of the soften.
As with different alloyed steels, corrosion is greatest at the surface of the metallic tub. Despite its lean nickel content material, 253 MA® alloy offers an excellent mixture of creep strength and high resistance to oxidation, sulphidation and erosion/abrasion at extraordinarily excessive temperatures. This makes the alloy extra economical than most heat resistant alloys. In addition to its superb oxidation resistance in air, Sandvik 253 MA can be highly immune to different atmospheres.
- The use of uncommon earth metals together with silicon offers superior oxidation resistance as much as 2000°F.
- Stainless 253 MA is a lean austenitic warmth resistant alloy with excessive strength and excellent oxidation resistance.
- 253 MA maintains its warmth resistant properties by advanced control of micro alloy additions.
Our stainless production range
The excessive warmth resistant properties of 253 MA® are obtained by the tight management of micro alloy additions. Whilst the benefit of creep rupture power is right down to the combination of nitrogen, carbon and cerium, its superior oxidation resistance is a results of the mix of cerium and silicon. 253 MA® was developed over 30 years in the past, when the necessity for a heat resistant chrome steel with excessive energy and good oxidation resistance was required within the business. Thermocouple protection tubes (pyrometer safety tubes) in a variety of excessive-temperature corrosion resistant supplies.
The extremely protective oxide layer makes it possible to use this steel at high temperatures in atmospheres containing sulphur and other aggressive compounds. four show that the resistance of Sandvik 253 MA in such tough circumstances is superior to that of each ASTM TP310 and EN 1.4828 (ASTM TP309). The superb properties of this grade in cyclic situations have been achieved by adding uncommon earth metals and silicon. S30815/253ma stainless steel is a nickel-resistant warmth-resistant austenitic stainless steel designed for applications requiring excessive creep energy and good corrosion resistance.
Therma 253 MA is a stainless steel with wonderful oxidation and creep resistance in cyclic conditions that’s best employed in temperatures as much as 1150 °C/2100 °F. There is a slight susceptibility to embrittlement during steady operation at 600–850 °C/1110–1560 °F. 253 MA options wonderful oxidation resistance at temperatures under 1093 °C, above which, its oxidation resistance will lower. The metallic components of silicon and rare earth parts contribute to their excellent oxidation resistance. The rare earth component enhances the diffusion price of silicon and repeatedly produces an oxide layer of SiO 2 silica, which slows down the development of oxidation.
Recommended Filler Metals
In gasoline shields containing little or no oxygen the resistance of Sandvik 253 MA is inferior to that of Alloy 800H and 25Cr/20Ni steels as illustrated in Fig. Thus, the grade just isn’t really helpful for use in muffle tubes utilizing cracked ammonia fuel.
