SK90 cov cuab yeej steel Cov lus qhia ntxaws
SK90 yog cov hlau muaj zog ultra-siab uas, los ntawm kev kho kom raug alloying, muaj cov khoom siv zoo heev thiab muaj peev xwm kho cua sov. Nws cov khoom tseem ceeb muaj xws li carbon (C), silicon (Si), manganese (Mn), chromium (Cr) thiab lwm yam, nrog rau me me ntawm molybdenum (Mo), cobalt (Co) thiab lwm yam khoom. Qhov sib ntxiv ntawm cov ntsiab lus no muab SK90 zoo heev hardness, hnav tsis kam thiab zoo heev qaug zog.
Cov ntaub ntawv parameter ntawm SK90 suav nrog cov hauv qab no
(1) Tshuaj muaj pes tsawg leeg: feem pua cov ntsiab lus ntawm C (carbon), Si (silicon), Mn (manganese), Cr (chromium) thiab lwm yam.
(2) Lub cev muaj zog: nrog rau qhov ntom ntom, thermal conductivity, linear expansion coefficient, thiab lwm yam.
(3) Cov khoom siv kho tshuab: suav nrog hardness, tensile zog, yield zog, thiab lwm yam.
(4) Kev kho cua sov ua haujlwm: suav nrog quenching hardness, tempering hardness, quenching deformation, tempering deformation, thiab lwm yam.
(5) Fatigue resistance: nrog rau kev qaug zog txwv, qaug zog lub neej, thiab lwm yam.
Kev paub txog cov ntsiab lus qhia txog SK90 Tool steel
Hardness thiab lub zog
SK90 muaj qhov zoo tshaj plaws hardness thiab lub zog. Nws hardness tuaj yeem ncav cuag HRC60-62, uas yog cov hlau tawv heev. Tsis tas li ntawd, SK90 muaj qhov zoo tshaj plaws khoov thiab compressive zog, uas lav nws lub neej kev pab cuam nyob rau hauv complex tej yam kev mob.
Kev kho cua sov muaj peev xwm
SK90 muaj peev xwm kho cua sov zoo, hauv cov txheej txheem kho cua sov kom zoo tuaj yeem tau txais cov qauv zoo tshaj plaws thiab cov khoom siv. Kev hnav zoo thiab kev cuam tshuam kuj tuaj yeem tau los ntawm kev kho cua sov txheej txheem xws li quenching thiab tempering.
Kev qaug zog
SK90 muaj kev qaug zog zoo heev thiab tsis ua rau qaug zog tawg thaum siv mus ntev. Qhov no yog vim nws cov khoom siv zoo heev thiab cov txheej txheem silicone, ua rau nws ruaj khov thiab txhim khu kev qha nyob rau hauv siab load thiab siab zaus ua haujlwm.
