Stainless Steel 347 Forgings are a type of stabilized austenitic stainless steel alloy that includes iron, along with 17–19% chromium, 9–13% nickel, and niobium or tantalum to help stabilize carbides. This unique blend helps reduce intergranular corrosion and boosts strength at high temperatures. The alloy boasts a tensile strength of about 515 MPa and a yield strength close to 205 MPa, all while offering impressive toughness and resistance to creep. Its mechanical properties hold steady even during thermal cycling, making it an excellent choice for parts that face high-temperature oxidation and harsh corrosive environments, all while ensuring great weldability and formability.

Stainless Steel 347 forgings have limitations in extreme temperatures above 1600°F (870°C), susceptibility to stress corrosion cracking in chloride environments, and reduced formability compared to some other stainless steel grades.
The forging temperature range for Stainless Steel 347 is typically between 2100°F (1149°C) and 2200°F (1204°C). It ensures optimal grain structure and mechanical properties for high-performance applications.
Stainless Steel 347 forgings require minimal maintenance, primarily periodic cleaning to remove contaminants. Regular inspection for corrosion or wear is recommended, along with ensuring proper lubrication for moving parts in harsh environments.
Stainless Steel 347 Forgings from Desta Steel are a go-to choice in industries that demand strength, stability, and resistance to corrosion, especially at high temperatures. You’ll find these materials in a variety of applications, such as chemical processing components, heat exchangers, aerospace systems, exhaust manifolds, pressure vessels, and turbine parts. They’re also essential in refineries and power generation plants, where being resistant to carburization and oxidation is a must. Thanks to the alloy’s ability to maintain stability during continuous heating and cooling cycles, it’s perfect for making flanges, valves, fittings, and shafts. With Desta Steel’s forged products, you can count on reliable performance even in the toughest service environments across industrial, petrochemical, and mechanical engineering fields.
