253 Ma High Alloy Stainless Steel Natural Color Steel Plate
253MA s30815 1.4835 Stainless steel is a lean austenitic heat
resistant alloy with high strength and outstanding oxidation
resistance. 253 MA maintains its heat resistant properties by
advanced control of micro alloy additions. The use of rare earth
metals in combination with silicon gives superior oxidation
resistance up to 2000°F. Nitrogen, carbon and a dispersion of rare
earth and alkali metal oxides combine to provide creep rupture
strength comparable to the nickel base alloys. 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 253 MA.
Stainless steel 253 MA is readily fabricated by standard commercial
procedures. In comparison to carbon steel, stainless steels are
tougher and tend to work harden rapidly. However, with positive
feeds and slow speeds combined with abundant cutting fluid this
alloys tendency to work harden may be minimized. 253MA contains
fairly low nickel content, which gives it some advantage in
reducing sulphide atmospheres when compared to high nickel alloys
and to Grade 310. The inclusion of high silicon, nitrogen and
cerium contents gives the steel good oxide stability, high elevated
temperature strength and excellent resistance to sigma phase
precipitation.
253MA is a kind of heat resistant Austenitic stainless steel
(Austenitic stainless steel), for high creep strength, creep
strength and good resistance to corrosion of application and
design.

253 MA has very high resistance to oxidation, especially under
cyclic conditions, due to the addition of reactive elements, such
as cerium (Ce). The high mechanical strength of Sandvik 253 MA
allows for thinner tube wall constructions compared with using
materials of the ASTM 310 type. Despite the material's high
strength, ductility is not reduced, and good formability is
maintained.
253MA is a grade combining excellent service properties at high
temperatures with ease of fabrication. It resists oxidation at
temperatures up to 1150°C and can provide superior service to Grade
310 in carbon, nitrogen and sulphur containing atmospheres. Another
proprietary designation covering this grade is 2111HTR. 253MA
contains fairly low nickel content, which gives it some advantage
in reducing sulphide atmospheres when compared to high nickel
alloys and to Grade 310. The inclusion of high silicon, nitrogen
and cerium contents gives the steel good oxide stability, high
elevated temperature strength and excellent resistance to sigma
phase precipitation. The austenitic structure gives this grade
excellent toughness, even down to cryogenic temperatures.
