Mechanical tests

Brinell hardness test according to EN ISO 6506-1 for each individual heat treatment/coil.

Hardness is measured on the milled surface 0.3-2.0 mm below the plate surface.

Charpy impact test according to EN ISO 148, 1 test/20 tons.

Tensile test according to EN ISO 6892 on each plate and thickness <19.9 mm.
