These Stainless Steel 347 Forgings are crafted from an austenitic chromium-nickel alloy, enhanced with niobium to prevent carbide precipitation during exposure to high temperatures. Typically, the chemical makeup consists of about 17–19% chromium and 9–13% nickel, with carefully controlled carbon content. These forgings boast impressive tensile and yield strength, outstanding toughness, and high ductility. They maintain their mechanical stability even at elevated temperatures, show strong resistance to creep, and offer good weldability, making them perfect for challenging thermal and mechanical service 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.
You’ll find Stainless Steel 347 Forgings in equipment that faces high temperatures and corrosive environments. Common applications include heat exchangers, pressure vessels, valve components, flanges, and fittings in chemical and petrochemical facilities. They’re also extensively used in power generation systems, oil and gas refineries, aerospace components, and furnace parts. Their ability to resist intergranular corrosion after welding makes them an excellent choice for fabricated and welded structures that demand a long service life, reliability, and top-notch performance under harsh operating conditions.
