Stainless Steel 347 Forgings are a type of stabilized austenitic stainless steel that includes chromium, nickel, and niobium (columbium) to help prevent intergranular corrosion. On the mechanical side, SS 347 boasts excellent tensile strength, toughness, and stability at high temperatures. Its stabilization process ensures it resists carbide precipitation during welding or when exposed to prolonged heat. Additionally, this alloy maintains strong oxidation resistance and keeps its shape even under thermal cycling. These characteristics make SS 347 forgings perfect for applications that demand long-lasting durability, corrosion resistance, and mechanical reliability in extreme conditions.

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.
Industries that need high-temperature performance, corrosion resistance, and mechanical strength frequently turn to Stainless Steel 347 Forgings. They’re commonly found in heat exchangers, boiler components, furnace parts, and chemical processing equipment. In the petrochemical, oil and gas, and power generation sectors, SS 347 forgings are ideal for reactor parts, flanges, manifolds, and fittings that face continuous thermal stress. Their excellent weldability and durability also make them a great fit for aerospace, fabrication, and heavy industrial applications. With SS 347 forgings, you can count on long-term reliability, strength, and stability, making them crucial for critical engineering projects.
