Sachiya Steel International is one Of The Leading Manufacturer And Exporter Of High Quality Stainless Steel 304 Pipes, where low nickel content of it makes them price stable. Stainless Steel 304 Seamless Pipes is mainly due to advances in steelmaking techniques particularly with respect to control of nitrogen content. The high mechanical strength of Stainless Steel 304 Welded Pipes is a result of the duplex microstructure and the alloying with nitrogen. Stainless Steel 304 Seamless Pipes are formed from an approximately 50 / 50 mixture of austenitic and ferritic phases and are sometimes referred to as austenitic – ferritic stainless steels.

Stainless Steel UNS S30400 ERW Pipes gives them a significant advantage over 300 and 400 series stainless steels. Stainless Steel 304 EFW Pipes has a higher strength material than conventional austenitic stainless steels and standard duplex grades. Stainless Steel 304 Round Pipes is used in a wide range of applications in industries such as oil, gas, paper, chemical, and marine. Stainless Steel 304 Square Pipes combine the best attributes of both austenitic and ferritic stainless steels and provide high strength/ductility with good corrosion resistance to corrosion (including stress corrosion cracking).
This high strength of Stainless Steel DIN 1.4301 Pipes gives opportunities for reducing both weight and cost as a thinner material can be used. The standard austenitic Stainless Steel 304 Hexagonal Pipes are relatively easy to make and to fabricate. As their names imply, Stainless Steel 304 Hallow Pipes consist mainly of one phase, austenite or ferrite.
