    Description

    St1kp steel is used: for the manufacture of parts with high viscosity and low hardness, the anchor bolts connecting the casings, non-critical valves, rivets, and other fasteners non-critical purposes; tube and pipe; two-headed rails, t-type P5, is designed for ground and suspended tracks; enamelware.

    Note

    The degree of deoxidation — KP.
