Khoom Description
SKD61 cov cuab yeej kub ua haujlwm hlau yog cov khoom siv zoo heev hauv kev tsim cov cuab yeej. Cia peb tshawb nrhiav nws cov khoom muaj pes tsawg leeg, cov khoom, thiab cov kev txwv tshwj xeeb.
Muaj pes tsawg leeg: SKD61 yog tsim los ntawm carbon, chromium, molybdenum, vanadium, thiab silicon. Kev sib xyaw ua ke ntawm cov ntsiab lus no muab cov hlau nws cov khoom tshwj xeeb. Piv txwv li, carbon muab hardness thiab lub zog, thaum chromium txhim khu kev hnav tsis kam thiab corrosion kuj. Molybdenum thiab vanadium pab txhawb kom kub kub lub zog thiab toughness.

Tshav kub SKD61 cov cuab yeej steel rau qhov kub thiab txias, tsau sijhawm txaus kom txog thaum Soak kom huv si. Qhov ntsuas kub li niaj zaus yog 400-650 degree (752-1202 degree F), Nws nyob ntawm cov cuab yeej hardness xav tau thiab qhov kub ua haujlwm. SKD61 tempering cov ntaub ntawv rau koj siv raws li hauv qab no:
| Kub [degree] | 400 | 500 | 550 | 600 | 650 |
| Hardness [HRc] | 54 | 56 | 54 | 49 | 47 |
Cov Kev Ntsuas Tshwj Xeeb: Lub hardness ntawm SKD61 tuaj yeem ncav cuag ib theem tom qab kev kho cua sov kom zoo. Nws lub zog tensile thiab lub zog tawm los kuj tseem ua tau zoo, muab cov khoom tsim nyog lub zog rau kev thov. Cov hlau muaj qhov tshwj xeeb kub muaj peev xwm thiab thermal expansion coefficient, uas yuav tsum tau xav txog thaum tsim thiab tsim khoom. Ntxiv mus, nws cov hardenability thiab tempering yam ntxwv ua lub luag haujlwm tseem ceeb hauv kev txiav txim siab nws cov khoom kawg.
Hauv kev xaus, SKD61 cov cuab yeej kub ua haujlwm hlau yog cov khoom siv zoo kawg nkaus nrog cov khoom sib npaug zoo, cov khoom zoo, thiab cov kev txwv tshwj xeeb uas ua rau nws yog qhov kev xaiv zoo tshaj plaws rau ntau yam kev siv kub ua haujlwm. Nws muaj peev xwm tiv taus qhov kub thiab txias, ua ke nrog nws lub zog, toughness, thiab hnav tsis kam, ua kom ntseeg tau qhov kev ua tau zoo thiab kev ua haujlwm ntev hauv kev xav tau kev lag luam ib puag ncig.
