20CrMnTi 18CrNiMo7-6 Forged Alloy Steel Blanks For Gear shaft Blanks

Product Specification

20CrMnTi 18CrNiMo7-6 Forged Alloy Steel Blanks For Gear|shaft Blanks. We produce high-quality forged alloy steel blanks made from 20CrMnTi and 18CrNiMo7-6, specifically designed for the production of gears and shafts used in heavy-duty mechanical systems. These blanks are forged to provide excellent toughness, wear resistance, and core strength, making them ideal for further machining into precision transmission components.

Material Grades:

• 20CrMnTi – A carburizing steel widely used for gears and transmission parts. It provides excellent surface hardness after heat treatment, with good core toughness and fatigue resistance.

• 18CrNiMo7-6 – A premium alloy steel with deep hardenability and outstanding performance in demanding gear and shaft applications. Offers high load capacity and long service life after carburizing and quenching.

Product Types:

• Gear blanks – forged round discs or hubs ready for gear cutting

• Shaft blanks – cylindrical or stepped shafts forged to near-net shape

• Custom shapes – according to drawing or specification

Key Features:

• Weight range: 50KG – 3000KG

• Precision forging with continuous fiber orientation

• Heat treatment options: normalizing, quenching & tempering, or carburizing

• Available in as-forged, rough machined, or pre-machined condition

• 100% Ultrasonic Testing (UT) and MPI to ensure internal soundness

• Mechanical and chemical test reports provided upon delivery

Applications:

• Automotive and truck gearboxes

• Wind turbine transmissions

• Heavy-duty machinery drive shafts and gear systems

• Mining and construction equipment

• Industrial gear reducers and couplings

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.
