Alloy 24 UNS S34565 1.4565 Super-Austenitic Forgings for FGD, Seawater & Chemical Service Shafts, Valve Parts, Tube Sheets Rings

Product Description

Jiangsu Liangyi is an ISO 9001:2015-certified forging manufacturer in China supplying Alloy 24 / UNS S34565 / W.Nr. 1.4565 (high-N super-austenitic stainless) open-die forgings, seamless rolled rings and shafts to FGD, seawater, chemical and oil & gas projects in India and worldwide, to ASTM A240 / A479 (F49), EN 10088 and SEW 400.

Why Alloy 24 / UNS S34565 for Indian FGD, seawater and chemical projects

Alloy 24 is a 24Cr-17Ni-4.5Mo-0.5N high-nitrogen super-austenitic stainless with PREN >40 (about three times 316L), high strength and seawater-grade corrosion resistance. For India's power (FGD), seawater, chemical and oil & gas sectors, S34565 suits FGD forgings, seawater pump and valve parts, shafts, tube sheets and rings often substituting for duplex, Alloy 31 or nickel alloys at lower cost.

Documented capability

FGD/power: scrubber/absorber forgings, shafts, valve/pump parts, tube sheets.

Seawater/marine: seawater pump/valve forgings, shafts, rings, structural parts.

Chemical/process: process-equipment forgings, vessels, tube sheets, nozzles, flanges (acids/alkalis).

Oil & gas/crude transport: crude-transport, wellhead, pressure-vessel forgings, shafts, rings.

Product range for Indian buyers
