Notes & safetyLow-hydrogen: must bake 350°C × 2h and hold in a 100–150°C quiver; re-bake if exposed over 4h. Diffusible hydrogen ≤4 ml/100 g. Mechanical: tensile ≥490 MPa, yield ≥400 MPa, elongation ≥22%, impact ≥27 J at −30°C. Recommended current — 2.5mm 70–100A · 3.2mm 110–150A · 4.0mm 150–200A · 5.0mm 200–260A.
