Product Description

Jiangsu Liangyi is an ISO 9001:2015-certified forging manufacturer in China supplying 34CrAlNi7-10 / W.Nr. 1.8550 open-die forgings, seamless rolled rings and bars to precision-mechanical, valve and plastics-processing projects in India and worldwide, to EN 10085.

Why 34CrAlNi7-10 / 1.8550 for Indian precision and plastics-processing projects

34CrAlNi7-10 is an aluminium nitriding steel that develops a very hard nitrided case (above 1000 HV, ~6570 HRC-equivalent) over a tough quenched-and-tempered core, with minimal distortion from low-temperature nitriding. For India's precision-gear, valve and plastics-processing sectors, 1.8550 suits nitrided gears, spindles, valve stems, extruder screws and barrels and wear components.

Documented capability

Precision gears/shafts: nitrided gears, pinions, gear shafts, spindles, precision shafts.

Valves/fluid equipment: valve stems and spindles, wear rings and sleeves.

Plastics processing: extruder screws and barrels, injection-machine parts, wear components.

General: bars, discs, hubs, custom forgings.
