DESCRIPTION 
Type 305 Stainless Steel is an austenitic chromium nickel stainless steel that can be cold worked and deep drawn more readily than Type 302 and Type 304 due to an increased nickel content that decreases the work hardening rate of the material. It is nonmagnetic and cannot be hardened by thermal treatment. 
 
PRODUCT FORMS 
Sheet, Strip 
 
SPECIFICATIONS 
ASTM A240, AMS 5514 
 
TYPICAL APPLICATIONS 
Deep drawn or spun components, eyelets, electronic enclosure applications. 
 
PROCESSING 
Type 305 is not hardenable by heat treatment. Anneal at 1850–2050°F, then water quench or rapid air cool. 
 
WELDING 
This alloy is generally considered to have comparable weldability to Types 304 and 304L, but autogenous arc welding sometimes causes hot cracking. Annealing after welding will be needed to offset any chromium carbide precipitation which might occur. When a filler is needed, AWS E/ER 308 is most often specified. 
 
CORROSION 
Type 305 is similar to Type 304 with respect to corrosion resistance. It offers good protection from a wide variety of solutions used in the chemical, textile, petroleum, dairy and food industries. 
 
FORMING 
Type 305 Stainless Steel is more readily formed, deep drawn and spun than Types 302 and 304 due to its lower work hardening rate.
