Heat, Hammer, and Precision: The Birth of a Forged D-Ring

1. Core Process: Die Forging

Alloy steel heated above 1100°C and forged in dies to form dense grain flow for maximum strength.

2. Key Step: Heat Treatment

Carry out quenching + high-temperature tempering treatment to achieve the optimal balance between high strength and toughness.

3. Precision Machining

Flash removal and machining of critical features ensure precise dimensions.

4. Surface Protection

Galvanizing or painting prevents corrosion; shot peening improves fatigue resistance.

5. Quality Testing

Mechanical tests, non-destructive inspection, and overload verification guarantee safety.

6. Applications

Used in lifting, shipping, construction, and rescue equipment for heavy-duty connections.

Advantages: Superior grain structure, high durability, mass-production capable, meets industry standards.
