ASTM A249 TP304L, UNS S30403 Stainless Steel Welded Tube For Heat Exchangers Boilers
ASTM A249 TP304L is a low carbon austenitic grade of stainless steel. The lower carbon content makes it easy welded and reduces corrosion. SS304L tube is tougher and has high wear and tear properties. The ASTM A249 TP304L welded tube has many advantageous properties, like its good formability and good weldable properties and so on. SS 304L welded Tube is widely used in heat exchangers, boilers, condensers, power generation and oil and gas plants.
