AISI 1045 Steel, cold drawn, high temperature stress relieved, 50-75 mm (2-3 in) round
Categories: Metal; Ferrous Metal; Carbon Steel; AISI 1000 Series Steel; Medium Carbon Steel
Material Notes: Respond to heat treatment, and flame and induction hardening, but not recommended for carburizing or cyaniding. Die forging and hot upsetting are good to excellent. Typical uses include gears, shafts, axles, bolts, studs, and machine parts. AISI cross reference for JIS S45C and KS SM45C.
