Large Size Alloy Steel Forged Cylinder – Heat Treated and Machined to Drawing
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.
Available Shapes:
Cylindrical forgings: solid round bars or hollow cylinders
Forged shafts: straight, stepped, or spline shafts
Gear blanks: round discs with or without hubs, pre-machined or rough
Block forgings: rectangular, square, or custom-shaped blocks for heavy-duty applications
Material Grades (examples):
42CrMo / 42CrNiMo / 18CrNiMo7-6 – high-strength alloy steels for mechanical parts
20CrMnTi – carburizing and quenching steels for gears
Key Features:
Custom forging weight range: 100 KG to 7000 KG
Superior mechanical properties after heat treatment
Uniform internal structure, no porosity or segregation
100% ultrasonic tested, with optional third-party inspection
CNC pre-machining and surface treatment available upon request
Applications:
Wind power equipment (shafts, gear blanks)
Heavy machinery and transmission systems
Mining, port, and oilfield equipment
Power generation and shipbuilding industries
Hydraulic systems and pressure equipment
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.
