Annealed & Off Tempered

Annealed and Off Temper Stainless Steel Wire

ASTM A313 & ASTM A580

Various grades of 300 and 400 series stainless may be supplied in a fully annealed state.  They can also be supplied in 1/8 hard, 1/4 hard and 1/2 hard as per the customer requirement. Or the customer can request a specific tensile range and if possible the wire can be produced to that range based upon the production capabilities of the supplier of the steel.
