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.
Claims (8)
1. A pre-alloyed stainless steel powder comprising at least 10% by weight of chromium, less than 0.1% by weight of carbon and less than 0.07% by weight of nitrogen, said powder further comprising vanadium in an amount of at least 4 times the combined amounts of carbon and nitrogen, wherein the amount of vanadium is 0.1-1% by weight.
2. The stainless steel powder according to claim 1, wherein the steel powder further comprises 10-30%
chromium and 0.5-1.5% silicon.
chromium and 0.5-1.5% silicon.
3. The stainless steel powder according to claim 1 or 2, wherein the steel powder comprises 10-20%
chromium, 0.15-0.8% vanadium, 0.7-1.2% silicon, less than 0.05% carbon and less than 0.05%
nitrogen.
chromium, 0.15-0.8% vanadium, 0.7-1.2% silicon, less than 0.05% carbon and less than 0.05%
nitrogen.
4. The stainless steel powder according to claim 1, 2 or 3, wherein the steel powder is essentially free from nickel.
5. A powder metallurgical composition comprising a stainless steel powder according to anyone of the preceding claims and additives selected from the group consisting of lubricants, flow agents, machinability improving agents and alloying elements.
6. A process of preparing compacted parts of stainless steel powder comprising the steps of:
- subjecting a steel powder according to anyone of claims 1 to 4 optionally mixed with a lubricant - sintering the compacted part at a temperature of 1150-1350°C.
- subjecting a steel powder according to anyone of claims 1 to 4 optionally mixed with a lubricant - sintering the compacted part at a temperature of 1150-1350°C.
7. The process according to claim 6, wherein sintering is made to a density of at least 7.20 g/cm3
8. A sintered part of stainless steel powder according to anyone of claims 1 to 4, having a sintered density of at least 7.20 g/cm3.
