Known Tradenames:

With the advent of the microalloying control, this alloy is comparably priced with 310 stainless-steel, nevertheless it delivers excessive power properties similar to the upper nickel Inconel® 600-collection supplies. In addition to its excellent oxidation resistance in air, Sandvik 253 MA can also be extremely immune to other atmospheres. The highly protecting oxide layer makes it potential to make use of this steel at excessive temperatures in atmospheres containing sulphur and other aggressive compounds. Sandvik 253 MA is often preferred as an alternative of stainless chromium steels which have inadequate creep power and structural stability. Furthermore, Sandvik 253 MA can very nicely take the place of higher alloyed materials such as 25Cr/20Ni steels and Alloy 800H, or even Alloy 600 in sure instances.

310 Stainless Steel – Austenitic warmth resistant grade with higher chromium and nickel for oxidation resistance beyond 2000°F. Compared with austenitic stainless steels, Sandvik 253 MA has good resistance to cyanide melts and neutral salt melts and likewise to metal melts, e.g. lead, at excessive temperatures. Its resistance to metal melts is to a great extent decided by the oxygen content material of the soften. As with different alloyed steels, corrosion is biggest at the floor of the metal bath. 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).

Due to this low pressure, local sulfidation assault can occur even when the atmosphere is considered oxidizing. ASME 2010 (2011 revision) Section II-D allowable design stresses for -vessel plate are shown in Figure 2. The allowable stresses for RA 253 MA are greater than both 310 stainless and RA 330 but not as high as Alloy 601. ASME has allowable design stresses for this alloy up to 1600˚F (871˚C), however RA 253 MA is used at greater temperatures for many different functions because this restrict is only for pressure vessels.

Our stainless production

  • Nitrogen, carbon and a dispersion of rare earth and alkali steel oxides mix to supply creep rupture similar to the nickel base alloys.
  • 253 MA maintains its heat resistant properties by superior management of micro alloy additions.
  • A broad variety of elements requiring excessive at elevated temperatures corresponding to warmth exchangers, kilns, stack dampers and oven parts are frequent applications for 253 MA.
  • Stainless 253 MA is a lean austenitic warmth resistant alloy with high strength and outstanding oxidation resistance.
  • The use of rare earth metals together with silicon gives superior oxidation resistance as much as 2000°F.

253 ma alloy

The inclusion of high silicon, nitrogen and cerium contents offers the metal good oxide stability, excessive elevated temperature power and glorious resistance to sigma section precipitation. Sandvik 253 MA is extra resistant than the higher alloyed 25Cr/20Ni steels to combustion gasoline attacks in cyclic situations.

253 ma alloy

Heat-resistant austenitically excessive-alloyed steel with cerium, used in isothermal circumstances, perfect for temperatures as much as oC. Typical sizzling tensile strengths of a of supplies are shown in Figure 1. Over most of the temperature ranges, it’s comparable to Alloy 600, superior to 310 stainless and RA 330® but lower than RA 602 CA®.

The use of rare earth metals together with silicon offers superior oxidation resistance up to 2000°F. Nitrogen, carbon and a dispersion of rare earth and alkali metal oxides mix to supply creep rupture strength similar to the nickel base alloys.

Other Gaseous Atmospheres

It has an equal resistance, compared to the same grades, in situations that are nearly isothermal. Sandvik 253 MA can be utilized in nitrogen-containing atmospheres supplied that the gasoline contains sufficient oxygen to type a protective oxide layer.
