Stainless Steel 304H Pipe Fittings is a high-carbon 304, used primarily for high temperatures. It generally contains 18-20% chromium, 8-10.5% nickel and a maximum of 0.04-0.10% carbon. The alloy provides excellent resistance to corrosion and oxidation and high resistance to pitting and crack corrosion. Mechanical properties include a tensile strength of 515 MPa (75 ksi), a yield strength of 205 MPa (30 ksi) and an elongation of 40%. It provides excellent weldability and is used in power plants, petrochemical industries and food processing.

Stainless Steel 304H Pipe Fittings consist of chromium (18–20%), nickel (8–11%), and more carbon (0.04–0.10%) than standard 304, which raises their tensile and yield strength. These fittings possess good resistance to oxidation as well as corrosion in high-temperature conditions and possess mechanical properties like tensile strength up to 585 MPa and yield strength of approximately 240 MPa. The added carbon improves creep resistance, making them suitable for applications involving long heat exposure.
