Abstract

Disclosed is a method for manufacturing a mechanical component, the method comprising applying an additive manufacturing method, wherein the method comprises depositing a powder material and locally melting and resolidifying the powder material, thereby providing a solid body, the method comprising chosing a powder material of the following chemical composition: elemental content of carbon larger than or equal to 0.04 wt % and less than or equal to 0.15 wt %, elemental content of manganese less than or equal to 1.00 wt %, elemental content of silicon less than or equal to 0.75 wt %, elemental content of phosphorus less than or equal to 0.03 wt %, elemental content of sulfur less than or equal to 0.015 wt %, elemental content of chromium larger than or equal to 20.00 wt % and less than or equal to 24.00 wt %, elemental content of cobalt less than or equal to 5.00 wt %, elemental content of iron less than or equal to 3.00 wt %, elemental content of aluminium larger than or equal to 0.20 wt % and less than or equal to 0.50 wt %, elemental content of titanium less than or equal to 0.10 wt %, elemental content of boron less than or equal to 0.015 wt %, elemental content of copper less than or equal to 0.50 wt %, elemental content of lanthanum less than or equal to 0.10 wt %, elemental content of tungsten larger than or equal to 13.00 wt % and less than or equal to 15.00 wt %, elemental content of molybdenum larger than or equal to 1.00 wt % and less than or equal to 3.00 wt %, wherein the difference of the sum of the elemental contents of all mentioned elements to 100 wt % is provided as nickel, and further selecting the powder material with an elemental content of carbon in a tighter range of larger than or equal to 0.04 wt % and less than or equal to 0.10 wt %, wherein wt % denotes weight percent.
