Description

60 steel is used: for the manufacture of solid-rolled wheels for railway rolling stock, rolls, work sheet mills for hot rolling metal, spindles, tires, clutch discs, spring rings shock absorbers, locking washers, shims, shims and other parts which have to meet the requirement of high strength and wear-resisting; cold-rolled heat-treated ribbon with a thickness of 0.05 to 1.30 mm and rolled heat-treated strip thickness 0.15−2.00 mm for the manufacture of spring details and springs, with the exception of the winding; tinned wire for the manufacture of tires rotors of electric machines; remises heat-treated tin-plated wire, designed for the manufacture of galev to reminyl devices looms.

Note

The degree of deoxidation — SP.
