Description

Steel St4ps is used: for the production of corner rolled steel, h-beam, channels, used in steel structures and construction; welded, riveted and bolted structures high strength; light duty parts such as shafts, axles, bushings; welded pipes; two-headed rails, t-type P5, is designed for ground and suspended tracks; crutches accuracy class, designed for fastening of rails to wooden sleepers and bars.

Note

The degree of deoxidation — PS.
