High-temperature Tubes

The steel is, nonetheless, slightly more resistant than ASTM TP304 to stress corrosion cracking in chloride bearing aqueous options. Its resistance is more or less the identical as that of ASTM TP316. Recuperator tubes in a wide range of high-temperature corrosion resistant materials appropriate for flue gas temperatures up to 1300ºC (2370ºF).

As can be seen, Sandvik 253 MA is much less vulnerable to carburization at high temperatures in these conditions than ASTM TP310 and Alloy 800H. When a fabric is uncovered to an oxidizing setting at elevated temperatures, a kind of protecting oxide layer will be formed on its floor. The alloying components which might be most helpful for oxidation resistance are chromium, silicon, and aluminum. A optimistic effect has additionally been achieved with small additions of so-called (re)energetic elements, e.g. yttrium, hafnium, and rare earth metals (REM, e.g. Ce and La).

Stainless 253 MA is a lean austenitic heat resistant alloy with high strength and excellent oxidation resistance. 253 MA maintains its warmth resistant properties by advanced control of micro alloy additions. The use of uncommon earth metals in combination with silicon provides superior oxidation resistance up to 2000°F. Nitrogen, carbon and a dispersion of rare earth and alkali steel oxides combine to supply creep rupture strength similar to the nickel base alloys. A extensive variety of parts requiring high energy at elevated temperatures such as warmth exchangers, kilns, stack dampers and oven components are widespread applications for 253 MA.

• The use of uncommon earth metals together with silicon gives superior oxidation resistance up to 2000°F.
• Stainless 253 MA is a lean austenitic heat resistant alloy with high energy and excellent oxidation resistance.
• 253 MA maintains its warmth resistant properties by superior management of micro alloy additions.

Our stainless production range

Stainless metal 253 MA is quickly fabricated by normal industrial procedures. In comparison to carbon steel, stainless steels are harder and tend to work harden quickly. However, with positive feeds and sluggish speeds combined with plentiful slicing fluid this alloys tendency to work harden could also be minimized. 253MA accommodates pretty low nickel content material, which supplies it some benefit in decreasing sulphide atmospheres when compared to excessive nickel alloys and to Grade 310.

Despite its comparatively low chromium and nickel contents, 253MA shares the identical excessive temperature properties because the high alloyed alloy steel and nickel-based alloy in lots of purposes. It obtains high temperature resistance by controlling hint parts. The combination of niobium and silicon offers the material an excellent oxidation resistance at temperature as much as 1093 °C. The mixture of nitrogen, carbon and niobium provides it a creep power twice as high as that of grade 310 and 309 at temperature of 871 °C.

Therma 253 MA is a stainless-steel with glorious oxidation and creep resistance in cyclic circumstances that is finest employed in temperatures up to 1150 °C/2100 °F. There is a slight susceptibility to embrittlement throughout continuous operation at 600–850 °C/1110–1560 °F. 253 MA options wonderful oxidation resistance at temperatures beneath 1093 °C, above which, its oxidation resistance will lower. The metallic components of silicon and rare earth elements contribute to their wonderful oxidation resistance. The uncommon earth element enhances the diffusion price of silicon and continuously produces an oxide layer of SiO 2 silica, which slows down the event of oxidation.

Recommended Filler Metals

These have an effect on the oxide progress so that the fashioned layer will be thinner, harder, and extra adherent, and thus extra protective. This is especially helpful in conditions with various temperatures. Sandvik 253 MA is more resistant than the upper alloyed 25Cr/20Ni steels to combustion fuel assaults in cyclic conditions. It has an equivalent resistance, in comparison with the identical grades, in situations which are virtually isothermal. Sandvik 253 MA may also be used in nitrogen-containing atmospheres provided that the fuel incorporates enough oxygen to type a protective oxide layer.
