Abstract

The invention relates to a hot forming tool for press hardening, wherein the tool comprises a main body and, partly or fully of a laser metal deposited surface layer, the main body consist of a tool steel alloy comprising 0.25 - 0.45 C, 0.10 - 1.50 Si, 0.2 - 1.0 Mn, 2 - 6 Cr, < 0.8 Ni, 1 - 3 Mo, 0.4 - 1.0 V, 0.001 - 0.06 Al, < 0.12 N, < 0.005 B and the laser metal deposited surface layer comprising 0.27 - 0.40 C, 0.10 - 0.35 Si, 0.2 -0.8 Mn, 4.0 - 6.0 Cr, < 0.8 Ni, 2.0 - 3.0 Mo, 0.4 - 0.6 V, 0.001 - 0.06 Al, 0.003 - 0.12 N. The laser metal deposited surface layer has a hardness of 53-59 HRC.
