By integrating forging, heat treatment, machining and inspection processes, Jiangsu Hui Xuan helps customers simplify supply chains and obtain reliable industrial components from one experienced manufacturer.

Customer Challenge: Reliable Forgings for Demanding Industrial Applications

South American industries, especially mining and heavy equipment sectors, operate in challenging environments where mechanical components must withstand:

• Heavy loads

• Continuous operation

• High impact conditions

• Long service requirements

For critical components, customers need more than a forging supplier. They need a manufacturing partner capable of controlling the complete production process:

• Material selection

• Forging process

• Heat treatment

• Machining accuracy

• Mechanical properties

• Quality documentation

A fragmented supply chain involving multiple suppliers can create:

• Higher communication costs

• Longer delivery cycles

• Difficult quality responsibility management

Jiangsu Hui Xuan provides a complete manufacturing solution:

Raw Material → Forging → Heat Treatment → Precision Machining → Inspection → Delivery

Project Example: Manufacturing High-Performance Forged Components

Jiangsu Hui Xuan produced multiple industrial forged components according to strict customer specifications.

The project included components such as:

• Quill Pinion

• Rocker Link

• Rocker Arm

• Gear Axle

• Link Axle

• Piston

• Threaded Ring

• Adjusting Spindle

The materials included:

• 42CrMo4

• 31CrMoV9

• C60/C60E

• 30CrNiMo8

• 4340

These materials are widely used for mechanical components requiring high strength, toughness and wear resistance.

One example was an Eccentric Gear Axle with a diameter of Ø484 mm and length of 2,634 mm, demonstrating Jiangsu Hui Xuan’s capability in manufacturing large-size forged components.

Forging Capability: Controlling Internal Quality from the Beginning

For this project, the required forging ratio was:

≥3:1

A controlled forging ratio improves:

• Internal structure uniformity

• Mechanical reliability

• Fatigue resistance

The steelmaking requirements included:

• Electric furnace or oxygen steelmaking process

• Vacuum degassing

• Hydrogen control: H <2 ppm

• Nitrogen control: N <80 ppm

• Oxygen control: O <20 ppm

These requirements ensure stable material quality before forging production.

Heat Treatment Expertise for High-Performance Forgings

Different materials require different heat treatment solutions.

For:

• 42CrMo4

• 31CrMoV9

• 30CrNiMo8

• 4340

The required process included:

Quenching + Tempering + Stress Relieving

For C60E:

Normalizing Treatment

The tempering temperature requirement was:

≥570°C

Stress relieving requirements:

• At least 30°C lower than tempering temperature

• Minimum temperature ≥550°C

Through controlled heat treatment, Jiangsu Hui Xuan ensures stable mechanical properties for demanding industrial applications.

Precision Machining: Adding Value Beyond Forging

Many forging suppliers only provide forged blanks.

However, industrial customers often need finished components with accurate dimensions and reduced processing requirements.

Jiangsu Hui Xuan provides:

Forging + Heat Treatment + CNC Machining + Final Inspection

This integrated capability helps customers achieve:

• Reduced supplier coordination

• Better dimensional control

• Lower total manufacturing cost

• Improved delivery efficiency

Our machining capability allows forged components to be delivered closer to final production requirements.

Quality Control and Inspection Capability

To meet international industrial requirements, Jiangsu Hui Xuan applies strict quality control procedures.

Inspection capabilities include:

Non-Destructive Testing

• Ultrasonic Testing: EN 10228-3 Grade 3

• Magnetic Particle Testing: DIN EN 10228-1 Grade 3

Metallurgical Quality Control

Including:

• Grain size inspection (Grade 6–8)

• Metallographic analysis

• Non-metallic inclusion control according to ISO 4967

For heat-treated components:

• Metallographic photos are provided

• Tempered sorbite structure verification is completed

Complete production records are maintained, including:

• Heat treatment records

• Mechanical test reports

• Inspection documents

• Manufacturing process photos

Cost Control Through Integrated Manufacturing

For South American customers, total purchasing cost includes more than product price.

The real cost includes:

Material Cost + Forging Cost + Machining Cost + Quality Risk + Logistics + Supplier Management

By combining forging and machining capabilities internally, Jiangsu Hui Xuan helps customers optimize:

• Production efficiency

• Supplier management

• Quality consistency

• Overall procurement cost
