Product Description

Jiangsu Liangyi is a ISO 9001-certified stainless steel forging manufacturer in China, supplying UNS S41500 / ASTM A182 F6NM (X3CrNiMo13-4 / W.Nr. 1.4313) forged bars, seamless rolled rings, hollow forgings, discs and custom parts to hydropower, oil & gas, nuclear, pump, valve and marine projects in India and worldwide.

Why UNS S41500 / F6NM / 1.4313 for Indian hydro, oil & gas and power projects

This soft martensitic 13Cr-4Ni-Mo stainless UNS S41500 / ASTM A182 F6NM in the American system, X3CrNiMo13-4 / 1.4313 in EN has low carbon (0.050%) giving high strength, high impact toughness (KV >70 J in +QT650/+QT780) and good weldability. It is the standard material for hydro-turbine runners and wicket gates, pump casings and wellhead parts that must resist wet and high-pressure service. For India's large hydropower and pumped-storage build-out, refinery and frac duty, S41500 / F6NM / 1.4313 is a direct fit, certified to whichever system your spec uses.

Documented deliveries

Hydropower: Jiangsu Liangyi supplied open-die turbine runner discs and wicket gates in S41500 / 1.4313 to EN 10222-5 for the 500 MW impulse-turbine unit at the Zala hydropower station.

Oil & gas: +QT780 frac-pump fluid-end blocks and wellhead spool bodies for a Middle Eastern oilfield, stable under high pressure for 2+ years.

Nuclear: reactor coolant-pump casing shells and trunnions for a third-generation nuclear unit, full traceability, all tests passed.

Pumps: custom pump impellers to EN 10272:2007 for a European chemical-pump maker.

Valves: seamless rolled rings for valve bodies and seats for a US petrochemical plant.

Turbines: +QT900 forged disks and rolled guide rings for a gas-turbine manufacturer.

Suited to India's hydro, pumped-storage and marine duty

The grade's toughness, weldability and resistance to cavitation erosion and wet/seawater corrosion make UNS S41500 / F6NM / 1.4313 ideal for Francis and Pelton runners, wicket gates, guide vanes and pump casings in conventional hydro and the pumped-storage projects expanding across India, plus marine propeller shafts and pump/valve parts for coastal and offshore service.
