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

Product Specification

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.

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.

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.

3. Which industrial sectors are the primary beneficiaries of your forged products? We cater to a diverse array of critical industries, including wind power generation, heavy machinery manufacturing, port infrastructure, power transmission systems, and various others.

4. What are the typical timeframes for the completion and dispatch of orders? For items readily available in our inventory, the standard lead time is approximately 30 days. For custom-manufactured orders, the timeframe generally spans 40 to 45 days.

5. Could you provide information on the geographical location of your manufacturing facility and shipping hub? Our production plant is situated in Changzhou City, strategically located near Shanghai, and we utilize the Port of Shanghai for our shipping logistics.
