STAL SZYBKOTNĄCA, ZWŁASZCZA NA NARZĘDZIA SKRAWAJĄCEHIGH-SPEED STEEL, ESPECIALLY FOR CUTTING TOOLS
Przedmiotem wynalazku Jest stal szybkotnąca, zwłaszcza na narzędzia skrawające. Znane i dotychczas stosowane stale szybkotnące zawierają w procentach wagowych 0,65 - 1,6 % węgla, max 0,5 % manganu, 3,0 - 5,0 % chromu, max 0,5 % niklu, do 22,5 % wolframu, do 9,5 % mooibdenu, 0,4 - 5,3 % wanadu, do 13,0 % kobaltu, max 0,3 % krzemu.The subject of the invention is high-speed steel, especially for cutting tools. Known and so far used high-speed steels contain in percentages by weight 0.65 - 1.6% carbon, max 0.5% manganese, 3.0 - 5.0% chromium, max 0.5% nickel, up to 22.5% tungsten , up to 9.5% mooybdenum, 0.4 - 5.3% vanadium, up to 13.0% cobalt, max 0.3% silicon.
Znane są również stale wolframowo-oolibeeoowoowanadowe zawierające w procentach wagowych około 6,0 % wolframu, 5,0 % mooibdenu i 2,0 % wanadu, lub 2,0 % wolframu, 9,0 % molibdenu, 2,0 % wanadu, stale bezwc^^jram^c^^e molibdenowo-wanadowe zawwernjące 8,0 % mooibdenu i 2,0 % wanadu oraz stale wolframowo-ooliMenowo-oanldowookobaltowe zawierające 2,0 % wolframu, 9,0 % mooibdenu, 1,0 % wanadu i 8,0 % kobaatu, w których zawartość krzemu Jest podwyższona do 1,0 %.There are also known tungsten-oolybee-vanadium steels containing in weight percent about 6.0% tungsten, 5.0% moybdenum and 2.0% vanadium, or 2.0% tungsten, 9.0% molybdenum, 2.0% vanadium, steels absolute ^^ jram ^ c ^^ e molybdenum-vanadium containing 8.0% mooybdenum and 2.0% vanadium and tungsten-ool Menoanldo-octobalt steels containing 2.0% tungsten, 9.0% mooybdenum, 1.0% vanadium and 8.0% of cobat, in which the silicon content is increased to 1.0%.
Znana jest rówiież z polskiego opisu patenoowego nr 125 293 stal wolframowoomooibdenowo-wanadowa oraz n^^o.^b^(^^r^o^wo^^nado^^,w których zawisłość mooiłdenu zawarta jest w przedziale 1,0 - 9,0 %, a zawartość krzemu 0,5 - 3,0 %♦ Stale znane i dotychczas stosowane zawwerają znaczne ilości kosztownych pierwiastków stopowych. Twardość stall szybkotnących w stanie zahamowanym i dwikkotnie lub kilkakrotnie odpuszczonym, w optymalnych warunkach, w zależności od składu chemicznego wynosi 62 - 68 HRC.We also know from the Polish patent description No. 125 293 tungsten ohmooibdenum-vanadium steel and n ^^ o. ^ B ^ (^^ r ^ o ^ wo ^^ nado ^^, in which mooilden hanging is in the range 1.0 - 9 , 0%, and the silicon content is 0.5 - 3.0%. ♦ The known and previously used steels will convert significant amounts of expensive alloying elements. The hardness of high-speed steels in the slowed state and in a double-cut or tempered state several times, under optimal conditions, depending on the chemical composition, is 62 - 68 HRC.
Stal według wynalazku zn^JLei^a w procentach wagowych 0,8 - 1,2 % węgla, 3,0 - 5,0 % chromu, 6,0 - 12,0 % wolframu, 0,3 - 3,0 % wanadu, 0,3 - 9,0 % kobaatu, max 0,5 % niklu, max 1,0 % mooibdenu, max 0,5 % manganu, 0,5-3,5 % krzemu, 0,04 - 0,20 % siarki, max 0,0A% fosforu, reszta żelazo.Steel according to the invention with n - 1.2% carbon, 3.0 - 5.0% chromium, 6.0 - 12.0% tungsten, 0.3 - 3.0% vanadium, 0.3 - 9.0% cobat, max 0.5% nickel, max 1.0% moybdenum, max 0.5% manganese, 0.5-3.5% silicon, 0.04 - 0.20% sulfur , max 0.0A% phosphorus, the rest is iron.
Przykładowo stal według wynalazku zawiera w procentach wagowwch: węggel - 1,15 %, mangan - 0,45 %, chrom - 4,0 %, nikiel - 0,3 %, wolfram - 9,5 %, moUbden - 0,3 %, warnad149 334For example, the steel according to the invention contains in percentages by weight: carbon - 1.15%, manganese - 0.45%, chromium - 4.0%, nickel - 0.3%, tungsten - 9.5%, moUbdenum - 0.3% , warnad149 334

2,5 %, krzem - 2,0 %, kobalt - 5,0 %, fosfor - 0,03 %, siarka - 0,08 %, żelazo - reszta.2.5%, silicon - 2.0%, cobalt - 5.0%, phosphorus - 0.03%, sulfur - 0.08%, iron - the rest.
Stal według wynalazku poddaje się obróbce cieplnej polegającej na hartowaniu, korzystnie z temperatury 1150° - 1200°C i dwu lub trzykrotyym odpuszczaniu w temperaturze 500 - 56O°C przez 1-2 godzin w stanie obrobionym cieplnie.The steel according to the invention is subjected to a heat treatment consisting of hardening, preferably from a temperature of 1150 ° -1200 ° C, and tempering twice or three times at a temperature of 500-56 ° C for 1-2 hours in the heat-treated state.
Stal według wynalazku wykazuje własności użytkowe porównywalne z odpowiednimi własno sciaM stali szybkotnących dotychczas stosowanych, przy znacznie niższych kosztach składników stopowych. Stal cechuje się również znacznie lepszą skrawaanoscią w stanie zMękczonym oraz lepszą szlifwwalnością w stanie obrobionym cieplnie od stali stosowanych dotychczas. Twardość stali w stanie obrobionym cieplnie w optymalnych warunkach wynosi 64-68HRC.The steel according to the invention shows functional properties comparable to the corresponding properties of the high-speed steels used so far, with significantly lower costs of alloy components. The steel is also characterized by much better machinability in the fractured state and better grindability in the heat-treated state than the steels used so far. The hardness of the steel in the heat-treated state under optimal conditions is 64-68HRC.
