NM500 is an abrasion resistant plate with a hardness of 500 HBW, intended for applications where demands are imposed on abrasion resistance in combination with good cold bending properties. NM500 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.
Thickness: 3mm to130mm
Width: 1450mm to 4050mm,
Length: 3000mm to 15000mm
