High-speed steel, tseem hu ua HSS, yog ib hom khoom siv hlau uas tau siv dav hauv kev tsim khoom lag luam vim nws cov khoom zoo heev. Nws yog cov khoom siv ua haujlwm siab uas tuaj yeem tiv taus qhov kub thiab txias thiab kev ua haujlwm siab ceev, ua rau nws zoo tagnrho rau cov cuab yeej txiav, laum cov khoom thiab lwm yam kev siv hlau ua haujlwm.
Ib qho ntawm cov khoom tseem ceeb ntawm high-speed steel yog nws lub peev xwm los tswj hardness thiab txiav peev xwm txawm nyob rau hauv high kub. Qhov no yog vim muaj cov ntsiab lus alloying xws li tungsten, molybdenum, chromium thiab vanadium, uas tsim cov carbides nyuaj hauv cov hlau matrix. Cov carbides no muaj peev xwm tiv taus hnav thiab tshav kub, tso cai rau cov hlau ceev ceev kom tswj tau nws txoj kev txiav txawm tias thaum nws raug cua sov thiab kev sib txhuam thaum ua haujlwm.

Lwm qhov tseem ceeb ntawm kev kub ceev steel yog nws zoo heev toughness thiab durability. Tsis zoo li lwm cov cuab yeej hlau, HSS muaj peev xwm tiv taus qhov cuam tshuam thiab kev poob siab yam tsis muaj chipping lossis tawg. Qhov no ua rau nws tsim nyog rau cov ntawv txiav hnyav uas lub cuab yeej raug rau cov quab yuam tseem ceeb thaum ua haujlwm.
Ntxiv nrog rau nws cov khoom siv kho tshuab, kev kub ceev steel kuj muaj kev ua haujlwm zoo, tso cai rau kev ua haujlwm zoo thiab meej thiab tsim cov txheej txheem. Qhov no ua rau nws yooj yim dua rau cov tuam txhab tsim cov cuab yeej siv cov cuab yeej siv HSS, tsim cov cuab yeej uas tuaj yeem ua tiav qhov kev ua siab ntev thiab ua tiav qhov siab.
HSS kuj tseem paub txog nws qhov kev ua tau zoo, vim nws tuaj yeem siv los ua ntau yam khoom siv, suav nrog carbon steel, alloy steel, stainless hlau, thiab cov hlau tsis muaj hlau. Qhov no ua rau nws yog qhov kev xaiv nrov rau cov cuab yeej siv dav dav uas xav tau los ua haujlwm sib txawv machining.

Tsis tas li ntawd, HSS tuaj yeem kho tau yooj yim thaum tshav kub kub kho kom ua tau raws li qhov xav tau ua ke ntawm hardness, toughness thiab hnav tsis kam, tso cai rau cov khoom siv kom haum rau cov ntawv thov tshwj xeeb. Qhov kev kho cua sov no tso cai rau cov tuam txhab ua kom zoo dua qhov kev ua tau zoo ntawm HSS cov cuab yeej txiav rau kev sib txawv machining thiab cov ntaub ntawv ua haujlwm.
Nyob rau hauv xyoo tas los no, kev nce qib hauv high-speed steel thev naus laus zis tau ua rau kev txhim kho cov qib steel tshiab thiab cov khoom sib xyaw uas muaj kev ua tau zoo dua. Cov kev nce qib no tso cai rau cov cuab yeej txiav steel high-speed los ua haujlwm ntawm kev txiav nrawm dua thiab kub, ua kom cov khoom tsim tau thiab txuag nqi rau cov tuam txhab.
Txawm hais tias qhov tshwm sim ntawm lwm yam khoom siv xws li carbide thiab ceramic inserts, high-speed steel tseem yog ib qho kev xaiv nrov hauv ntau cov ntawv siv hlau vim nws qhov kev ua tau zoo ntawm kev ua tau zoo, kev siv nyiaj tsawg, thiab kev siv yooj yim. Nws muaj peev xwm tiv taus qhov kub thiab txias, tswj qhov ntse txiav ntug, thiab tiv taus hnav thiab cuam tshuam ua rau nws muaj kev ntseeg siab thiab ntau yam khoom siv rau ntau yam kev txiav thiab kev ua haujlwm.
Hauv cov ntsiab lus, HSS yog cov khoom tseem ceeb hauv kev tsim khoom nrog kev sib xyaw ua ke ntawm hardness, toughness, hnav tsis kam thiab machinability. Nws muaj peev xwm ua tau zoo ntawm kev kub ceev thiab kub kub ua rau nws yog ib qho kev xaiv tseem ceeb rau kev txiav cov cuab yeej thiab lwm yam kev siv hlau ua haujlwm. Nrog rau kev tshawb fawb thiab kev tsim kho tsis tu ncua, HSS xav tias yuav hloov mus ntxiv kom tau raws li qhov xav tau ntawm cov txheej txheem machining niaj hnub no.
