High Light Heavy Duty Forged CylinderForged Cylinder 100kg7000kg Open Die Forging

Heavy Duty Forged Cylinder – Open Die Forging – Custom Alloy Steel 100kg to 7000kg


    Our Heavy Duty Forged Cylinders are produced using advanced open die forging technology, ensuring excellent internal soundness, grain flow, and superior mechanical properties. Manufactured from high-quality alloy steels such as 42CrMo, 42CrNiMo, 18CrNiMo7-6, and C45, these forged components are ideal for use in hydraulic systems, gearboxes, marine shafts, pressure vessels, and wind turbine main shafts.


Each forged cylinder can be supplied in rough machined or fully CNC machined condition according to your drawings, with weights ranging from 100kg to 7000kg. We offer custom forging services, including heat treatment, UT/NDT inspection, and mechanical testing. Our cylinders meet international standards including ISO, GB, and DIN and are trusted by OEMs in energy, offshore, and heavy machinery industries.

The steel forgings production flow:

Raw material steel ingot into warehouse(test the chemical composition) → Cutting→ Heating(Furnace temperature test) → Heat treatment after forging(Furnace temperature test) Discharge the furnace(blank inspection)→ Machining→ Inspection(UT,MT,Visal dimension, hardness)→ QT→ Inspection(UT, mechanical properties, hardness, grain size)→ Finish machining→ Inspection (dimension)→ Packing and Marking(steel stamp, mark)→ Storage Shipment.

Frequently Asked Questions (FAQs)

  1. What is the typical weight spectrum of the forged components you manufacture? Our forging capabilities encompass a range of components weighing from 100 kilograms up to 7 metric tons.

  2. Do you handle downstream processing such as thermal treatment and material removal? Indeed, we provide comprehensive in-house services for heat treatment, encompassing both preliminary and final machining operations.
