Abstract

A powder or powder granulate includes a chromium content >80 Ma %, which contains 2 to 20 Ma % iron, optionally up to 5 Ma % dopant, and optionally up to 2 Ma % oxygen, wherein the chromium-containing particles at least partially have pores. The powder displays significantly improved compression behavior and allows the production of sintered components having a very homogeneous distribution of the alloy elements.
