Quantity
As a senior fastener engineer, I can confirm that the DIN W.Nr.2.4617 Thread Rod, manufactured from Hastelloy B-2, represents a premium solution for critical bolting applications. Produced by a reliable China Supplier, this threaded rod complies with DIN, NF, and ANSI standards, with dimensions of M12 × 200 mm. It delivers a tensile strength of 690 N/mm² and 40% elongation, balancing high load capacity with sufficient ductility for thermal and mechanical cycling.
Corrosion Performance & Validation
The material’s outstanding corrosion resistance has been verified through systematic testing under aggressive conditions, which is a key consideration when sourcing any DIN Thread Rod from a China Supplier for severe service.

- Corrosion Test (ASTM G31): In 20% HCl at 25°C for 24 hours, the corrosion rate measured 0.08 mm/year; in 50% H₂SO₄ under the same conditions, it was 0.06 mm/year. Both values are well within the ≤0.1 mm/year industry requirement. This exceptionally low attack rate is attributed to the high Ni-Mo content, which forms a stable passive film in reducing acids.
- Intergranular Corrosion Test (ASTM G28): Specimens were boiled for 24 hours in ferric sulfate–50% H₂SO₄ solution. Post-test metallographic examination revealed no grain boundary attack, cracks, or pores – intergranular corrosion depth measured 0 μm. This confirms that the manufacturing and heat treatment processes effectively prevent carbide precipitation, ensuring structural integrity even at elevated temperatures.
Engineering Assessment
From a design and procurement perspective, this DIN Thread Rod offers three definitive advantages:
From a design and procurement perspective, this DIN Thread Rod offers three definitive advantages:
1. Reliable acid resistance – verified corrosion rates ≤0.1 mm/year in strong mineral acids, directly translating to extended maintenance intervals.
2. No intergranular susceptibility – validated by ASTM G28, eliminating the risk of premature failure in welded or heat-affected zones.
3. Proven traceability – full compliance with DIN, NF, and ANSI dimensional and mechanical requirements, facilitating global project acceptance.
