ASME SA 249 TP 304L Welded Stainless Steel Tubing

ASTM A249 304L ERW Boiler Tube manufacturer

SA 249 Tp 304l is a low carbon austenitic popular grade of stainless steel. Typically the alloy Sa-249 Tp304l is considered to be a versatile one, with many advantageous properties. One such property is its good formability which is why the alloy can be easily shaped and formed into the specified A249 Tp 304l Stainless Steel Welded Tubing. Moreover, the ASTM A249 304l Welded Pipe has good weldable properties and can be welded using conventionally practised techniques.

ASTM A249 Tp 304l unlike its parent grade alloy 304, is specifically designed to combat the problems associated with welding.  ASTM A249 Tp304l is immune to carbon precipitation at the grain boundary. Apart from its reliability and durability properties, the ASME SA 249 Tp304l is appreciated for being economical as well.

Key sectors such as pharma along with the food and beverage industry favour Stainless Steel 304l Erw piping because they do not react with the various chemical substances present in the product being processed. Also, this partiality is due to the fact that the material used to build A249 304l Erw Tubing is less prone to getting corroded as compared to carbon based steels.
