GRADE GUIDE · S355JR
S355JR is the high-strength end of the common structural range: 355 MPa minimum yield — half again stronger than S235 — while staying weldable with normal workshop practice. It is the grade of crane parts, heavy frames, lifting equipment and any design where a smaller section must do a bigger job.

Choosing S355 is usually a weight decision: the 50% yield advantage over S235 lets designers shrink sections, which on a large frame saves more money than the grade premium costs. Heavy transport structures, crane booms, mobile equipment and offshore-adjacent fabrication all default to it.
It remains a friendly steel — cold-formable within sensible radii and weldable without preheat at common thicknesses, though thick, restrained joints deserve a look at the carbon equivalent on the certificate. Off-cuts in S355 tend to come from serious fabrication, so plate in useful thicknesses is a regular find.
Whenever strength sets the section size — beams at span limits, lifting gear, wheels-and-axles work. If deflection or simple fit governs, the extra yield goes unused and S275 is the economical buy.
Slightly more care, not different methods: at common thicknesses it welds without preheat, but check the carbon equivalent on thick or restrained joints. Low-hydrogen consumables are good practice.
St52-3 is the old DIN designation for essentially this steel, and the name survives in Gulf trading. Modern certificates read S355JR (or J0/J2 for tougher impact grades) to EN 10025-2.
