AISI 309H UNS S30909 Higher Carbon Heat Resistant Stainless Forgings for Furnace, Boiler and Superheater Parts Rings, Flanges and Bars Jiangsu Liangyi

Product Description

Jiangsu Liangyi is an ISO 9001:2015-certified forging manufacturer in China supplying AISI 309H / UNS S30909 open-die forgings, rings, flanges and bars to furnace, boiler, power and high-temperature process projects in India and worldwide, to ASTM A182 F309H.

Why 309H / S30909 for Indian high-temperature projects

309H is the higher-carbon, creep-strengthened version of heat-resistant 309 ~23% Cr for oxidation/scaling resistance to ~1095 C plus controlled higher carbon for elevated-temperature and creep strength. For India's power, furnace, boiler and high-temperature process sectors, it suits furnace/boiler components, superheater/reheater parts, radiant tubes and thermal-processing fixtures.

Documented capability

Furnace/boiler: furnace and boiler components, high-temperature internals, support rings.

Superheater/power: superheater and reheater parts, high-temperature power-plant components.

Radiant tubes/retorts: radiant tubes, retort parts, thermal-processing fixtures.

High-temperature process/general: high-temperature flanges, valves, pumps; rings, discs, hubs, sleeves, bars.

Product range for Indian buyers

Forged furnace and boiler components; superheater and reheater parts; high-temperature process and power-plant equipment; radiant tubes and retort parts; thermal-processing fixtures and support rings; high-temperature flanges, valve bodies and pump components; rings, discs, hubs, sleeves and bars.
