Title (EN) MARTENSITIC STEEL HAVING A Z-PHASE, POWDER AND COMPONENT
(FR) ACIER MARTENSITIQUE À PHASE Z, POUDRE ET ÉLÉMENT
(DE) MARTENSITISCHER STAHL MIT Z-PHASE, PULVER UND BAUTEIL
Abstract:
(EN) The invention relates to a steel having the following composition: carbon (C): 0.08% - 0.12%, preferably 0.10%; silicon (Si): 0.04% - 0.08%; manganese (Mn): 0.08% - 0.012%; chromium (Cr): 9% - 11%; molybdenum (Mo): 0.4% - 1.0%; tungsten (W): 1.6% - 2.4%; cobalt (Co): 2.5% - 3.5%; nickel (Ni): 0.10% - 0.24%; boron (B): 0.006% - 0.01%; nitrogen (N): 0.002% - 0.01%; titanium (Ti): 0.008% - 0.03%; vanadium (V): 0.015% - 0.029%; niobium (Nb): 0.03% - 0.07%; optionally copper (Cu): 1.00% - 2.5%; aluminum (Al): 0.04% - 0.10%; the remainder being iron (Fe), wherein said steel has improved properties, since no further Z-phase formation occurs.
(FR) L'invention concerne un acier composé de carbone (C) : 0,08 % – 0,12 %, de préférence 0,10%, de silicium (Si) : 0,04 % – 0,08 %, de manganèse (Mn) : 0,08 % – 0,012 %, de chrome (Cr) : 9% – 11%, de molybdène (Mo) : 0,4 % – 1,0 %, de tungstène (W) : 1,6 % – 2,4 %, de cobalt (Co) : 2,5 % – 3,5 %, de nickel (Ni) : 0,10 % – 0,24 %, de bore (B) : 0,006 % – 0,01 %, d’azote (N) : 0,002 % – 0,01 %, de titane (Ti) : 0,008 % – 0,03 %, de vanadium (V) : 0,015 % – 0,029 %, de niobium (Nb) : 0,03 % – 0,07 %, eventuellement de cuivre (Cu) : 1,00 % - 2,5 %, d’aluminium (Al) : 0,04 % - 0,10 %, le reste étant constitué par du fer (Fe), lequel acier présente des propriétés améliorées du fait que la phase Z ne se développe pas davantage.
(DE) Ein Stahl mit der Zusammensetzung Kohlenstoff (C): 0,08% – 0,12%, vorzugsweise 0,10%, Silizium (Si): 0,04% – 0,08%, Mangan (Mn): 0,08% – 0,012%, Chrom (Cr): 9% – 11%, Molybdän (Mo): 0,4% – 1,0%, Wolfram (W): 1,6% – 2,4%, Kobalt (Co): 2,5% – 3,5%, Nickel (Ni): 0,10% – 0,24%, Bor (B): 0,006% – 0,01%, Stickstoff (N): 0,002% – 0,01%, Titan (Ti): 0,008% – 0,03%, Vanadium (V): 0,015% – 0,029%, Niob (Nb): 0,03% – 0,07%, optional Kupfer (Cu): 1,00% - 2,5%, Aluminium (Al): 0,04% - 0,10%, Rest Eisen (Fe) weist verbesserte Eigenschaften auf, da die Z-Phase sich nicht weiter ausbildet.
