Abstract

The invention concerns a stainless steel powder and composition comprising at least 10w-t% chromium. Vanadium is present in an amount of at least 4 times the amount of carbon and nitrogen. The steel powder comprises 10-30% chromium, 0.1-1.0 vanadium, 0.5-1.5% silicon, less than 0.1% carbon and less than 0.07% nitrogen. A process for preparing a sintered part and a sintered part are also claimed.
