Type 305 (UNS S30500) is an austenitic chromium-nickel flat rolled stainless steel that has excellent corrosion resistance due to a higher nickel content. This increased nickel content also allows the alloy to be used for deep drawing applications.
305 stainless steel flat rolled coil is used mainly in applications that require corrosion resistance.
305 Stainless Steel Specifications:
ASTM A240 for annealed condition
ASTM A666 for tempered material*
305 Stainless Steel Applications:
Food Processing
Dairy industry
Kitchenware
Appliances, Kitchen utensils, Tank covers, Steam traps
Magnetic properties:
305 flat rolled stainless steel is a non-magnetic alloy that cannot be hardened by heat treatment.
Forming:
Type 305 has excellent formability that allows it to be used where deep drawing is necessary.
