Description

St3kp steel is used: for the manufacture of expanded metal sheets, lightly loaded elements and nesvorny welded structures and components operating at temperatures from -40 °C to +400 °C; the profiles used in the railcar industry; forgings seniam to 300 mm. strength classes KP 175, KP 195; hot pan and C-shaped profiles for agricultural machinery; corrugated steel rhombic and point for shipbuilding; profile housing final drive of the tractor; welded pipes for the manufacture of parts and structures in motovelotehnika; hot-rolled steel sheets with one-sided rhombic and lenticular corrugated; two-headed rails, t-type P5, is designed for ground and suspended tracks; steel bent closed welded square and rectangular sections, intended for use in agricultural machinery, tractor and other sectors of the economy; crutches accuracy class, designed for fastening of rails to wooden sleepers and bars.

Note

The degree of deoxidation — KP.
