    Super Austenitic 3 Inch Stainless Steel Tubing , Welded Stainless Steel Seamless Pipe

    Super Austenitic Stainless Steel Pipe ASTM A312 253MA Pipe 3 inch diameter​

    253MA is a grade combining excellent service properties at high temperature 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. These properties are specified for flat rolled product (stainless steel plate, sheet and coil) as Grade S30815 in ASTM A240/A240M. Similar but not necessarily identical properties are specified for other products such as pipe and bar in their respective specifications.

    Ø EN 1.4835 has a good weldability and can be welded using the following methods:

    • Shielded metal arc welding (SMAW)

    • Gas tungsten arc welding, GTAW (TIG)

    • Plasma arc welding (PAW)

    • Gas metal arc GMAW (MIG)

    • Submerged-arc welding (SAW)
    • Typical application areas for 1.4835:
    • Ovens
    • Construction
    • Building
    • As details at high temperature


    By using 1.4835 (UNS S30815 – 253MA – SS2368) you get a Stainless High Temperature Steel designed to be used at temperatures over 550°C. It has a good resistance to oxidation and suits to be used as details in ovens, construction and buildings.

    The steel grade 1.4835 ( also called UNS S30815, 253MA and SS2368) is an austenitic stainless high temperature steel with good resistance to oxidation. The steel has been designed to be used at temperatures over 550°C, the most suitable temperature range is 850-1100°C. The steel suits for production of details with good resistance to temperature corrosion and relatively high strength at elevated temperatures. It also has good creep strength properties. 1.4835 is not magnetic but can be slightly magnetic after cold working or welding.

    Good formability and weldability
    1.4835 has a good weldability and can be welded with shielded metal arc welding, gas tungsten arc welding, plasma arc welding and submerged-arc welding. You shall use low heat input and use filler metals of type EN 1.4835 when you weld. The steel can be both cold and hot formed but it can only be hardened by cold working. The steel has high hardness and at machining you need to follow cutting recommendations.
