Stainless Steel 347 forgingsconsist of iron with a composition of 17-19% chromium, 9-13% nickel, and 0.04-0.10% carbon, along with small amounts of manganese (2.00%), silicon (1.00%), and molybdenum (0.75%). The titanium content is 5 times the carbon content, which guarantees stabilization of the alloy and prevents carbide precipitation at high temperatures. Its mechanical properties include tensile strength of 520-860 MPa, yield strength of 205 MPa, and elongation of 40-50%. The material is kept under high temperature for resistance to oxidation and corrosion and serves very high-stress applications in industries such as aerospace, chemical processing, and power generation.

Stainless Steel 347 forgings are constrained by their inability to perform in extreme temperatures exceeding 1600°F (870°C), their vulnerability to stress corrosion cracking in chloride environments, and their diminished formability relative to certain other stainless steel grades.
The forging temperature range for Stainless Steel 347 generally falls between 2100°F (1149°C) and 2200°F (1204°C). This guarantees ideal grain structure and mechanical characteristics for demanding applications.
Stainless Steel 347 forgings need little upkeep, chiefly routine cleaning to eliminate contaminants. Periodic checks for corrosion or wear are advised, as well as making sure moving parts are properly lubricated in demanding environments.
Stainless Steel 347 forgingspossess outstanding resistance to high-temperature oxidation and corrosion, which makes them highly desirable. Their main use is within the aerospace, chemical processing, and power generation sectors for applications in extreme conditions. These forgings are exceptionally well-suited to furnace parts, heat exchangers, and reactor cores where intergranular corrosion and thermal stability are extremely important. Their applications encompass chemical and petrochemical valves, pumps, and fittings; Stainless Steel 347 also delivers excellent performance in high temperature settings, withstands acidic conditions, and offers several beneficial properties for highly demanding industrial processes.
