NM450 is an abrasion resistant plate with a hardness of 450 HBW, intended for applications where demands are imposed on abrasion resistance in combination with good cold bending properties. NM450 offers very good weldability.
Supplementary Technology: Brinell hardness, HBW according to EN ISO 6506-1, on a milled surface 0,5–2 mm below plate surface per heat and 40 tons. Tests are made for every variation of 15 mm in the thickness of plates from the same heat.
