Applications/Examples of results
〓■Introduction of Adoption Results■〓 1) Marine-related Existing product: SUS410 bolt (hardened product, over 900N) Incident: An accident occurred due to the aging cracking (delayed fracture) phenomenon of SUS410. User request: A bolt that does not experience aging cracking while maintaining strength. Adoption result: 7 years (no reports of similar incidents) 2) Joint-related Existing product: SCM435CS (equivalent to 10.9) Incident: The fastening bolt of the piping joint broke due to long-term deterioration. A potential difference corrosion phenomenon occurred due to the body being made of SUS material. User request: The bolt's strength cannot be reduced in design, but SUS material is desired to prevent potential difference corrosion. Adoption result: 4 years (no reports of similar incidents) and more・・・
