VT machining offers CNC Routing for S355JR Steel (EN 10025 / 1.0045 / ~Q345B), typically supplied hot-rolled. Higher-strength structural steel, yield ≥355 MPa.
CNC Routing Notes for S355JR Steel
Routing is only economical in S355JR Steel for thin sections; for thicker plate we usually recommend milling, laser or waterjet instead.
For estimating, a 100 × 100 × 10 mm block of S355JR Steel weighs about 0.79 kg.
