Core Technical Details
1. Material & Mechanical Properties
- Material Grade: Austenitic Stainless Steel AISI 304 / A2-70.
- Finish: Passivated (Bright) for superior oxidation and weather resistance.
- Ultimate Tensile Strength: 700 N/mm² (MPa) (Minimum).
- Yield Strength (0.2% Offset): 450 N/mm² (MPa) (Minimum).
- Elongation: 20% – 40%.
2. Manufacturing & Quality Standards
- Thread Type: Rolled Threads (Metric Coarse). Provides higher fatigue resistance and structural integrity compared to cut threads.
- Thread Tolerance: Class 6g according to ISO 965.
- Bending Process: Cold-formed with a controlled internal radius to prevent stress concentration and structural cracking.
3. Installation & Maintenance
- Environment: Suitable for general construction, pipe supports, and anchoring in non-marine environments. For coastal or high-chloride areas, AISI 316 (A4) is recommended.
- Matching Hardware: Best used with matching DIN 934 Hex Nuts and DIN 125 Flat Washers to avoid galvanic corrosion.
- Anti-Galling: It is highly recommended to apply Nickel-based Anti-Seize lubricant during installation to prevent thread locking (cold welding).
