High-strength stainless steel bolts and nuts (A2-90/A2-100) at an unbeatable price! A remarkable stainless steel fastener!
The next-generation stainless steel "SUS 304CUN," developed by Daido Steel, adheres to the chemical composition of JIS B 1054 A2 (304 series) while enabling cold forging. This material has been adjusted in composition to improve aspects related to high strength. By adding CU (copper) and N (nitrogen), it achieves an increase in strength while ensuring non-magnetic properties! *For more details, please contact us or download the PDF.

basic information
【Features】 1. By adding Cu (copper) and N (nitrogen), we achieve improved strength while ensuring non-magnetic properties. Adding Cu (copper) secures workability comparable to SUS XM7. Adding N (nitrogen) suppresses the generation of strain-induced martensitic transformation. 2. In terms of stress corrosion cracking, it has performance equivalent to SUS 316. 【SUS304CUN】 A2-90/A2-100 Hex Bolts A2-100 Hex Socket Bolts A2-100 Hex Nuts A2-90 Cut Bolts 【SUS304N2】 HV300 Flat Washers High Strength: High-strength bolts that meet A2-90 and A2-100 standards. (A2-100 is age-hardened) Corrosion Resistance: Equivalent to SUS 316 regarding stress corrosion cracking. Heat Resistance: No carbon precipitation occurs at 500-700℃. Non-Magnetic: Permeability (μ) is 1.01 to 1.03. Availability: Procured and produced domestically! Mass production and supply are also possible! Cost: High cost-performance ratio (specification comparison). *For details, please contact us or download the PDF.

Applications/Examples of results
【Marine Related】 Existing Product: SUS410 Bolt (Hardened Product, 900N or more) 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 Record: 7 years (no reports of similar incidents) 【Fitting Related】 Existing Product: SCM435CS (Equivalent to 10.9) Incident: The fastening bolt of the piping fitting 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 Record: 4 years (no reports of similar incidents) *For details, please contact us or download the PDF.
