Description

10kp steel is used: for the manufacture of sheet metal, 1−2 mm 4−14 category, intended for cold forming; sheet rolled double-sided electrolytic coating and single-side polymer coating, used in the construction industry, commercial engineering, industrial ventilation, household appliances, decoration and other purposes; parts, operating at temperatures up to +450 °C, which are requirements of high plasticity; bushings, lugs, washers, screws and other parts after HTO (chemical heat treatment), requirements of high surface hardness and wear resistance at low strength core; welded pipes; enamelware; cold strip 0,05−4,00 mm, designed for bending, punching parts, manufacture of pipes, cored wire, parts, bearings and other metal products.

Note

The degree of deoxidation — KP.
