Product Description

Jiangsu Liangyi is an ISO 9001:2015-certified forging manufacturer in China supplying AISI 310MoLN / UNS S31050 / W.Nr. 1.4466 (urea-grade austenitic stainless) open-die forgings, seamless rolled rings and flanges to urea, nitric-acid, chemical and power projects in India and worldwide, to ASTM A182 (F310MoLN) / EN 10088-3.

Why 310MoLN / UNS S31050 for Indian urea and chemical projects

310MoLN is a fully-austenitic, low-carbon, nitrogen-strengthened molybdenum stainless designed for urea plants, resisting carbamate corrosion in high-pressure strippers with no intermetallic phases. For India's urea/fertiliser, nitric-acid, chemical and power sectors, S31050 suits stripper and reactor forgings, tube sheets, flanges and rings.

Documented capability

Urea plants: high-pressure stripper forgings, reactor/carbamate-condenser parts, tube sheets, flanges, rings.

Nitric acid/chemical: reactor/exchanger forgings, nozzles, tube sheets, flanges.

Power/high-temperature: boiler and furnace forgings, rings, components.
