ASTM A249 Stainless Steel 304 Seamless Tubes / SS 304L/ 304H ERW Tube

Dinesh Tube is one of the prominent Supplier & Exporters of ASTM 312 Stainless Steel 304 Welded Tubes. We supply Stainless Steel 304 Tubes in various types like SS 304 Seamless Tubes, SS 304 Welded Tubes, SS 304 ERW Tubes, SS 304 LSAW Tubes, SS 304 Fabricated Tubes. Stainless Steel 304 Welded Tubes, which is exposed to stronger bases such as sodium hydroxide at high concentrations and high temperatures will likely experience some etching and cracking, especially with solutions containing chlorides such as sodium hypochlorite. Stainless Steel 304 ERW Tubes is slightly higher than standard austenitic stainless steels (ASTM 304L and 316L). Normal expanding methods can be used in these Stainless Steel 304 ERW Tubes, but the expansion requires higher initial force and should be undertaken in one operation. Stainless Steel 304/ 304L/ 304H Round Tubes are useful for storing and handling acetic acid, especially in solutions where it is combined with formic acid and when aeration is not present, though 304 provides the greatest level of resistance to corrosion. Intergranular corrosion may be compromised if Stainless Steel 304 ERW Tubes are heated between 800 degrees F (427 c) and 1650 F (899 C) or cooled slowly through that range. Stainless Steel 304 ERW Tubes contain up to 0.08 % carbon therefore subject to sensitisation and ‘weld decay’ – corrosion after heating to about 650 °C as would usually occur in the heat affected zone adjacent to a weld.
All our Stainless Steel 304 Welded Tubes conform to international standards and are manufactured according to ASTM, ASME, DIN, ANSI, EN, WERKSTOFFE, JIS, BS standards. Dinesh Tubes supplies a full range of specialized Stainless Steel 304/ 304L/ 304H Welded Tubes used for high-performance gas chromatography (GC) and liquid chromatography (LC) as components for chromatography columns used for analytical and preparative processes in diverse industries. Each piece of Tubes is fully tested by professionals according to international standards. Also available at best possible rates in the market.
