Delivered High-Precision Forged Components for the German Industrial Market

From Forging Capability to Precision Machining Excellence: A Complete Manufacturing Solution for European Customers

In the European industrial equipment market, especially in Germany, customers are not only looking for a forging supplier. They need a manufacturing partner who can control the complete process chain — from material selection and forging technology to heat treatment, precision machining, inspection, and final delivery.

JIANGSU HUI XUAN NEW ENERGY EQUIPMENT CO., LTD. provides integrated forging and machining solutions for global industrial customers, combining advanced forging technology, precision machining capability, strict quality control, and competitive manufacturing costs.

This case demonstrates how Hui Xuan successfully supported a German customer requiring high-performance forged components with strict mechanical properties, dimensional accuracy, and traceability requirements.

Customer Challenge: A German Customer Needed More Than Just Forgings

A German industrial customer required forged steel components for demanding operating conditions. The project requirements included:

• High-strength alloy steel materials

• Stable mechanical performance after heat treatment

• Strict internal quality requirements

• Controlled machining accuracy

• Complete manufacturing traceability

The requested materials included:

• 42CrMo4 according to EN10250-3

• 30CrNiMo8

• 31CrMoV9 according to EN10085

• C45 / C60E carbon steel grades

• ASTM A29 1045 and 4340 materials

The material specifications required controlled chemical composition and low impurity levels, including hydrogen, nitrogen, and oxygen control during steelmaking.

For this type of component, the biggest challenge was not simply producing a forged blank — it was achieving stable quality throughout the entire manufacturing process.

Manufacturing Solution: Integrated Forging + Precision Machining Process

1. Controlled Forging Process for Improved Material Integrity

Hui Xuan applies professional forging technology to improve internal material structure and mechanical reliability.

For this project, the required forging ratio was:

Forging Ratio ≥ 3:1

This ensures sufficient deformation of the steel structure, helping improve:

• Internal density

• Grain flow direction

• Mechanical strength

• Fatigue resistance

The forging process is carefully controlled from raw material preparation to final inspection, ensuring consistency between different production batches.

2. Advanced Heat Treatment Control

After forging, the components undergo professional heat treatment according to material requirements.

The process included:

• Quenching and tempering for alloy steels such as 30CrNiMo8, 42CrMo4, and 31CrMoV9

• Normalizing treatment for C45 and C60E materials

For quenched and tempered components, Hui Xuan controls tempering temperature above 570°C to achieve stable mechanical properties.

The company also monitors:

• Hardness values

• Tensile strength

• Yield strength

• Elongation

• Impact performance

Each production batch is traceable through heat number and heat treatment records.

3. Precision Machining: The Key Competitive Advantage

Many forging suppliers can produce rough forged parts. However, European customers increasingly prefer suppliers who can provide machined and ready-to-install components.

This is where Hui Xuan creates additional value.

Precision machining capability includes:

Rough Machining

After forging and before heat treatment, machining allowance is controlled according to drawing requirements.

Typical allowance:

• 10–15mm before heat treatment

• 3–5mm secondary machining allowance after heat treatment

This machining strategy ensures:

• Reduced deformation risk

• Better dimensional stability

• Improved final machining accuracy

Final Machining Capability

Hui Xuan focuses strongly on precision machining after heat treatment.

The machining process controls:

• Dimensional tolerance

• Straightness

• Radial runout

• Surface quality

For customer requirements, final machining can achieve:

• Drawing-defined dimensions

• Surface roughness requirements

• ISO 2768-1 general tolerance compliance

The company’s advantage is not only producing forged parts but transforming forged materials into precision-engineered components ready for assembly.

Quality Control System Designed for German Standards

To meet European customer expectations, Hui Xuan implements multi-stage inspection throughout production.

Non-Destructive Testing

The project required:

• Ultrasonic Testing according to EN 10228-3 Grade 3

• Magnetic Particle Testing according to DIN EN 10228-1 Grade 3

Additional metallurgical inspections included:

• Grain size control: Grade 6–8

• Inclusion control according to ISO 4967

• Metallographic verification of tempered martensite structure

Production Transparency and Traceability

For international customers, manufacturing transparency is essential.

Hui Xuan provides production progress documentation covering:

• Before normalizing

• Before rough machining

• Before heat treatment

• Before final machining

This allows customers to understand every important manufacturing stage and improves confidence in overseas supply chain management.

Project Results: A Reliable Partner for German Customers

Through integrated manufacturing capability, Hui Xuan successfully delivered forged components that met strict European industrial requirements.

Customer Benefits:

1. Reduced Supplier Management Complexity

Instead of coordinating multiple suppliers for:

• Forging

• Heat treatment

• Machining

• Inspection

customers can rely on one integrated manufacturing partner.

2. Improved Component Reliability

Controlled forging ratio, heat treatment, machining process, and inspection system ensure stable product performance.

3. Better Cost Control

By combining forging and precision machining internally, Hui Xuan helps customers achieve:

• Lower procurement costs

• Shorter supply chain

• Faster communication

• More stable delivery performance
