Description

The hot rolled, unalloyed quality steel S355K2 is a fine grained steel for dynamic loaded welding constructions. Dimensioning advantages in respect to the S235J2 due to the by 120 MPa higher yield strength. The steel shows a by 15% higher resistance to mineral wear due to sliding action in comparison to S235J2. The steel is not intended for heat treatment. Stress relieving annealing is allowed. Products in the delivery condition +N may be hot formed and/or normalized after delivery. For long products and continuous rolled flats the delivery condition is up to the producer +AR, +N or +M. The delivery condition of four-high rolled sheet is also up to the producer and may be +AR or +N. Both conditions can be ordered. For this steel are available (mat. no 1.0594, S355K2C) grades for folding, roll forming to shape and cold drawing.
