AISI 305 (UNS S30500)
Austenitic Stainless Steel
305 Stainless Steel Overview
Chemistry, mechanical properties, physical properties, and practical selection notes for rolled AISI 305 products.
Higher nickel lowers work-hardening rate good for deep drawing and multi-stage forming.
Typically non-magnetic in annealed and cold-worked conditions.
Higher nickel than 304 → lower work-hardening; good for deep drawing without intermediate anneals.
Non-magnetic in annealed and cold-worked conditions (per RMP).

About Stainless Steel AISI 305
305 stainless steel from Source21 is a specialized austenitic stainless steel grade engineered for exceptional deep drawability and smooth forming performance. With higher nickel content and a lower work hardening rate Type 305 stainless steel allows complex shapes to be formed with minimal stress clean surfaces and uniform wall thickness making it ideal for demanding deep drawing applications. It is commonly used in battery housings instrument cases electronic shielding components and deep drawn cans or shells where precision appearance and consistency are critical.
Source21 supplies 305 stainless steel in coil, strip, sheet, foil, and bar, all manufactured to meet ASTM A240 and ASTM A666 standards.
