Description
St5ps steel is used: for the manufacture of parts riveted structures, bolts, nuts, handles, rods, bushings, undercarriage rollers, wedges, pins, levers, stops, pins, fingers, rods, sprockets, tubular grilles, flanges and other parts operating at temperatures from 0 °C to +425 °C; forgings seniam to 800 mm. strength classes KP 175, KP 195; forgings seniam to 300 mm. strength KP 215; forgings seniam to 100 mm. strength KP 245; hot rolled C-shaped profile for agricultural machines; knives for earth-moving machinery (bulldozers, scrapers, graders and graders, as well as to the dozer and grader blades equipment excavators, rollers and other earth moving machines); two-headed rails, t-type P5, is designed for ground and suspended tracks.
Note
The degree of deoxidation — PS.
