1.4913 X19CrMoNbVN11-1
Steel 1.4913 X19CrMoNbVN11-1 is a high-strength quenching steel suitable for high temperature applications that is not corrosion resistant. It falls within the range of materials suitable for the production of fasteners for applications involving -200° to +700°C defined by ISO 267-13 and ISO EN 10269. Steel 1.4913 X19CrMoNbVN11-1 is particularly used for applications up to a maximum of 500°C obviously with a considerable drop in mechanical properties (at 500°C Rm = 335 MPa). This alloy is especially used for endothermic engine parts, pumps, piping and valves.
