JIS G4304 / G4312 SUS 305J1 Stainless Steel Composition & Low Work‑Hardening Austenitic Properties
SUS 305J1 is a low work‑hardening austenitic stainless steel defined in JIS G4304 / G4312. With increased nickel content (10.5–13%), it maintains a stable austenitic structure and becomes a typical deep‑drawing stainless steel.
305J1 hardens slowly during forming, reducing cracking and uneven deformation. It is ideal for complex‑shaped sheet components such as deep‑drawn containers, appliance panels, kitchen equipment, and electronic housings. SUS 305J1 is supplied as cold‑rolled sheets, strips, and thin plates. It offers excellent stability and formability for demanding forming applications.
