Abstract

The invention concerns steel obtained by powder metallurgy, formed from a sintered and densified high purity pre-alloyed powder. The invention is characterised in that the steel weight composition is as follows: manganese < 1 %; silicon < 1 %; chromium 6.05-6.45 %; molybdenum 2.50-3.50 %; vanadium 0.80-2 %; tungsten < 0.5 %; sulphur < 0.020 %; phosphorus < 0.030 %; niobium 0.60-1.60 %; cobalt 2 to 5 %; nitrogen 0.050 to 0.080 %; aluminium < 0.060 %; carbon 0.75-0.95 %; nickel < 0.50 %; the rest being iron and the standard impurities involved in steel manufacture.
