Description

St6ps steel is used: for the manufacture of Bab hammers, spindles, wedges, construction scrap and other parts exposed to impact loads; parts of high strength (axles, shafts, fingers, pistons, etc.); two-headed rails, t-type P5, is designed for ground and suspended tracks.

Note

The degree of deoxidation — PS.
