E335
1.0060Highest-strength unalloyed structural steel in EN 10025-2 — former designation St60-2 (DIN 17100). Higher C and Mn than S355 giving UTS 570-710 MPa. Not intended for welding (high CEV). Used for shafts, axles, bolts, and machine parts where weldability is not required but higher strength than S355 is needed. "E" designates engineering steel (vs "S" for structural).
