Precision Forged Steel Cylinder – 42CrMo / 20CrMnMo – CNC Machined or Rough Finished

 

Our Precision Forged Steel Cylinders are manufactured using open die forging processes and are available in either CNC machined or rough finished conditions. Made from premium-grade 42CrMo and 20CrMnMo alloy steels, these cylinders offer excellent tensile strength, impact resistance, and dimensional stability, making them ideal for gearboxes, hydraulic systems, marine applications, and industrial machinery.

Each forged cylinder is customized according to client specifications, with weights ranging from 100kg to 7000kg. We provide complete services including heat treatment (quenching, tempering), ultrasonic testing (UT), and mechanical property certification. Our cylinders are widely used by OEMs in the wind energy, port equipment, and power transmission sectors.

All components comply with ISO9001, DIN, and GB standards, ensuring long service life and stable performance in harsh operating environments.

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.
