Brand name: SUS 304CUN
This is a high-strength stainless steel fastener made from SUS 304CUN.
SUS 304CUN is an austenitic stainless steel (A2) that boasts high strength (A2-90, A2-100), high heat resistance, high corrosion resistance, and non-magnetic properties, making it a strong and rust-resistant high-strength material. By adding copper (CU) and nitrogen (N), it is possible to increase strength while ensuring non-magnetic properties, and it has stress corrosion cracking resistance comparable to SUS 316. Furthermore, SUS 304N2, which is SUS 304 with added nitrogen (N) and niobium (Nb), is a stainless steel that enhances strength while minimizing the reduction in ductility. It is used in structural strength members and high-pressure vessels. High-strength stainless steel washers that can withstand A2-100 specifications using SUS 304N2 have also been developed. These washers prevent plastic deformation (dimpling) around the holes of the mating components that occurs during tightening with high-strength fasteners, providing a locking effect against loosening.
