ASTM A249 TP304 1.4301 UNS S30400 Stainless Steel Welded Tube， Bright Annealed Tube
TP304 is the most widely used Austenite Stainless Steel， because it has good properties and strong corrosion resistance. TP304 is typical 18 Chromium – 8 Nickel stainless steel. TP304 is also known as AISI304. ASTM A249 TP304 stainless steel welded tubes is always required for pressure system. ASTM A249 stainless steel welded tube has good properties for boilers， super heaters， heat exchangers and condensers， particularly because it provides good corrosion resistance and high strength.
ASTM A249 TP304 Stainless Steel Welded Tubes offers high performance for industries like agriculture， manufacturing， oil & gas， which require reliable and rugged performance. ASME SA249 TP304 SS Welded Tubes are also used in other industries including Power， Fertilizers， Heat-Exchangers， Paper & Pulp， Pharmaceuticals， Chemicals， Water Treatment， Dairy， Sugar & Food Processing， etc..
