305 Stainless Steel
UNS S30500
Developed to meet the need for a ductile chromium-nickel stainless with a reduced tendency to work harden during spinning, stamping and forming. Type 305, or the “free spinning grade,” was formed. The nickel content of the nominal 18-8 composition was increased and the chromium content was decreased to meet this need. Due to lower rate of work hardening, Type 305 needs considerably less process annealing as compared to Type 302 and 304. Final grinding and polishing is required less with this grade, which will make costs lower for the final product. Resistance to abrasion is favorable.
Type 305 is used for complex conical shapes, excessively deep drawing, expanded metal parts, small diameter deep containers or sleeves and spinning metal.

PROCESSING:
Type 305 is not hardenable by heat treatment. Anneal at 1850 – 2050°F (1010 – 1121°C), then water quench or rapid air cool.
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.
WELDING:
This particular 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.
