ASTM A240 305 Stainless Steel Composition & Low Work‑Hardening Properties
ASTM A240 305 (UNS S30500) is a low work‑hardening austenitic stainless steel grade under ASTM standards. With 17–19% chromium and 10.5–13% nickel, it maintains a stable austenitic structure, providing excellent deep‑drawing and stretching performance.
305 hardens slowly during forming, reducing the risk of cracking and uneven deformation. It is ideal for complex‑shaped sheet components such as deep‑drawn containers, appliance panels, kitchen equipment, and electronic housings. Its corrosion resistance is comparable to 304, performing well in atmospheric and food‑grade environments.
305 is supplied as cold‑rolled sheets, strips, and thin plates. As the deep‑drawing‑optimized version of the 304 family, it offers superior stability and formability for demanding forming applications.
