Material Introduction & Manufacturing Process
The most commonly used materials for DIN431 pipe nuts are stainless steel grades A2 (304) and A4 (316). A2-70 is suitable for general corrosion environments, while A4-80 is used in marine, chemical, and highly corrosive applications.
Manufacturing Process:
- Raw Material Inspection: Premium stainless steel rods are inspected for composition and mechanical properties.
- Cold/Hot Forging: Raw bars are forged into hex shapes.
- CNC Thread Cutting: Internal threading is accurately machined.
- Heat Treatment (if applicable): For enhancing strength.
- Surface Finishing: Passivation or polishing to increase corrosion resistance.
- Quality Control & Packaging: Every batch undergoes controlled testing before dispatch.
