Characteristics of Stainless Steel Sheet and Plate:
High corrosion resistance
High toughness and impact resistance
High workability, including machining, stamping, fabricating and welding
Smooth surface finish that can be easily clean
The alloying components that are most useful for oxidation resistance are chromium, silicon, and aluminum. A constructive effect has also been achieved with small additions of so-known as energetic elements, e.g. yttrium, hafnium, and uncommon earth metals (REM, e.g. Ce and La). These affect the oxide development in order that the shaped layer will be thinner, more durable, and extra adherent, and thus more protecting.
The changeover to Sandvik 253 MA made it potential to run the recuperators at larger temperatures, thus saving considerably on vitality/gas consumption. At the same time, a manufacturing enhance of 60% has been achieved.
One of Turkey’s largest steel producers wanted to reduce energy consumption, extend the service life of furnace recuperators and simultaneously enhance manufacturing. To make it attainable, the recuperators, essential for recovering outgoing warmth from the furnaces, had to be able to run at greater temperatures. The problem was to find a steel grade, which might resist these larger temperatures and meet the new vitality reduction, service life and production calls for. Stainless steel 253 MA is quickly fabricated by normal commercial procedures. In comparison to carbon steel, stainless steels are more durable and have a tendency to work harden quickly.
The chemical composition of Avesta 253 MA has a balanced ferrite content material of max. Stainless 253 MA is a lean austenitic warmth resistant alloy with excessive power and excellent oxidation resistance. 253 MA maintains its warmth resistant properties by advanced management of micro alloy additions.
- Rutile coated electrode, designed for welding the high-temperature chrome steel 253 MA®, used for furnaces, combustion chambers, and burners.
- Both the steel and filler metal offers glorious resistance to oxidation to 1100 give °C.
- The chemical composition of Avesta 253 MA has a balanced ferrite content of max.
- 253 MA maintains its warmth resistant properties by superior management of micro alloy additions.

The resistance of a cloth to high-temperature corrosion is in lots of circumstances depending on its ability to form a protective oxide layer. In a reducing environment, when such a layer can’t be created , the corrosion resistance of the material will be determined by its alloy content. Although not designed for aqueous corrosion resistance the excessive chromium and nitrogen contents give the grade a pitting resistance approximating that of 316.
It is beneficial that the material be solution treated after 10-20% cold work to achieve maximum creep energy in service. 253MA will turn out to be sensitised within the temperature range of °C; this is not a problem for top temperature purposes, but will end in decreased aqueous corrosion resistance. 253MA has excessive power at elevated temperatures so is usually used for structural and stress-containing functions at temperatures above about 500°C and up to about 900°C. Its power at these temperatures is larger than that of options such as Grade 310. Carburisation – Under oxidising circumstances this grade can perform nicely, but alloys with larger nickel content material are most popular if the ambiance is decreasing.
ferritic chrome steel
253MA does nonetheless have a excessive carbon content so is extremely susceptible to sensitisation from welding or service exposure. 253MA is a grade combining wonderful service properties at high temperatures with ease of fabrication. It resists oxidation at temperatures up to 1150°C and might present superior service to Grade 310 in carbon, nitrogen and sulphur containing atmospheres. Seamless excessive-temperature tubes and furnace tubes suitable for use in functions with temperatures above 500ºC (932ºF). After contacts with materials specialists from Sandvik, the customer decided to put in tubes in Sandvik 253 MA into four recuperators.
To facilitate the usage of Therma 253 MA on the highest temperature range, TIG, plasma, or MAG processes must be used. Welding with MAG might require modern pulse equipment, and the use of particular shielding gases containing Ar, He, and O2/CO2 to facilitate good arc stability and improved fluidity. Recuperator tubes in a variety of excessive-temperature corrosion resistant materials suitable for flue gasoline temperatures up to 1300ºC (2370ºF). Muffle tubes in a wide range of excessive-temperature corrosion resistant materials. The Sandvik program of muffle tubes consists of supplies suitable for all sorts of defending gases and environments, overlaying service circumstances as much as 1200ºC (2190ºF).
