Toolox® 44 Round Bars
Download data sheet
Pre-hardened, precise, predictable steel, now in round bars.
Toolox® round bars are pre-hardened, ready-to-use quenched and tempered tool steels that come in a wide range of diameters from small to large.
Suitable for engineering applications in tool holders and in different types of shafts and rolls, the diameter dimensions also provide a better solution for round parts in tooling applications like molding and in dies for aluminium die casting.
|Diameter (mmin)||Hardness 1)
|21.0 - 282.00.827 - 6.772||410 - 475|
1) Hardness is measured, according to EN ISO 6506-1, on a milled surface 0.5 - 2 mm below the plate surface. Bar hardness is measured on a milled surface, with indents positioned as impact test according to EN 10 083.
