Description
Steel St3gsp usedfor producing h-beam, channels, angle steel, used in the manufacture of load-bearing elements of welded structures operating at variable loads at temperatures from -20 °C to +425 °C; the two-headed rails, t-type P5, is designed for ground and suspended tracks; steel moulded profile for mining equipment.
Note
The degree of deoxidation — SP.
