S355JR
1.0045High-strength low-alloy structural steel with minimum yield strength of 355 MPa. Standard grade for bridges, buildings, cranes, and general structural applications. Impact tested at +20°C (JR).
S275JR
1.0044Medium-strength structural steel with minimum yield strength of 275 MPa. Bridges the gap between S235JR and S355JR. Used for general structural applications, lattice towers, masts, and light crane components. Impact tested at +20°C (JR).
C10
1.0301Low-carbon unalloyed steel. Excellent weldability, good formability, and low hardness. Used for pins, rivets, bushings, case-hardened parts with thin case depth, and general cold-formed components. Can be case-hardened for surface wear resistance.
