Alloy Steel Forgings For Gear Shafts And Heavy-Duty Transmission Components

Our Alloy Steel Forgings for Gear Shafts and Heavy-Duty Transmission Components are manufactured with premium-grade alloy steels such as 42CrMo4, 18CrNiMo7-6, and 30CrNiMo8. These forgings are designed to deliver exceptional mechanical performance under high load and continuous operation.

Key Features:

• High tensile strength and excellent toughness for demanding industrial environments

• Superior wear resistance and fatigue strength, ensuring long service life

• 100% ultrasonic testing (UT) and strict heat treatment to guarantee internal soundness and dimensional accuracy

• Customizable dimensions and material grades to meet project-specific requirements

Applications:
These alloy steel forgings are widely used in:

• Gear shafts for wind power gearboxes, mining machinery, and port equipment

• Transmission components in heavy-duty industrial machines, steel mills, and petrochemical plants

• High-performance rotating parts where reliability and durability are critical

By combining advanced forging processes with strict quality control, we ensure that every gear shaft and transmission component meets the highest international standards.

Steel Forgings Production Process

Raw material verification → unloading and sorting → dimensional and surface check → preheating and temperature control → precision forging → controlled heat treatment → quality inspection → rough machining → non-destructive testing (UT/MPI) → final inspection → protective packaging → shipment to customer.

Frequently Asked Questions (FAQs)

What is the weight capacity of your forged products?
Our production covers forged pieces ranging from approximately 100 kg to 7,000 kg, suitable for both medium and large-scale industrial applications.

Do you offer additional processes like heat treatment and machining?
Yes. We operate a fully equipped in-house facility for thermal treatment, rough machining, and precision finishing to deliver parts that meet customer specifications.

Which industries make use of your forgings?
Our components are widely applied in wind energy, heavy-duty equipment, port handling systems, metallurgical operations, and other high-demand engineering fields.
