AISI 305 stainless steel strip
Excellent formability, very low work‑hardening, high ductility.
Description
AISI 305 (EN 1.4303, X4CrNi18-12) is an austenitic stainless steel with higher nickel than 304. The more stable austenite drastically reduces work-hardening and martensite formation during cold forming: the material stays soft, draws easily and remains practically non-magnetic even after stamping. It is ideal for electronic components, shielding, caps, sensor parts, tubes and multi-stage deep-drawn parts where magnetism and springback must be kept to a minimum. 3S supplies AISI 305 precision strip mainly annealed 2R/BA, as strip, narrow strips from 3 mm, spools and sheets from 0.05 to 0.70 mm.
Properties
- Low work-hardening rate
- Remains practically non-magnetic after forming
- Excellent for deep drawing and multi-stage stamping
- Corrosion resistance comparable to 304
