Solid Forged Cylinder – C45 / 42CrNiMo – For Pressure Vessels and Marine Applications
Our Solid Forged Cylinders are manufactured from high-strength alloy steels such as C45 and 42CrNiMo, making them ideal for pressure vessels, marine shafts, and heavy-duty industrial applications. Produced using open die forging techniques, these cylinders feature excellent internal soundness, fatigue resistance, and uniform grain flow, ensuring long service life in demanding environments.
Available in weights from 100kg to 7000kg, each forged cylinder can be supplied in rough turned or CNC precision machined condition, with full heat treatment options including normalizing, quenching, and tempering. All products undergo ultrasonic testing (UT) and comply with international standards such as ISO 9001, GB/T, and DIN.
We offer OEM customization services based on client drawings and specifications, serving customers in the shipbuilding, offshore energy, petrochemical, 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.
