Metal powder for use in an additive method for the production of three-dimensional objects and method using such metal powder

摘要

A metal powder for use in an additive production method of three-dimensional objects is disclosed. The powder is solidified by means of a laser or electron beam or another heat source and contains iron and the following components by weight percent (wt.-%):carbon: 0.07 max. wt-%,chromium: 14.00-15.50 wt.-%,nickel: 3.5-5.0 wt.-%, andcopper: 3.0-4.5 wt.-%.;The powder particles have a median particle size d50 between 20 μm and 100 μm.
