Chitsulo chothamanga kwambiri, chomwe chimatchedwanso HSS, ndi mtundu wazitsulo zomwe zimagwiritsidwa ntchito kwambiri popanga mafakitale chifukwa cha zinthu zake zabwino kwambiri. Ndizinthu zogwira ntchito kwambiri zomwe zimatha kupirira kutentha kwambiri komanso ntchito zopangira makina othamanga kwambiri, zomwe zimapangitsa kuti zikhale zabwino kwambiri pazida zodulira, zobowola ndi ntchito zina zopangira zitsulo.
Chimodzi mwa zinthu zofunika kwambiri zachitsulo chothamanga kwambiri ndi kuthekera kwake kukhalabe ndi kuuma ndi kudula luso ngakhale kutentha kwambiri. Izi zimachitika chifukwa cha kupezeka kwa zinthu zophatikizika monga tungsten, molybdenum, chromium ndi vanadium, zomwe zimapanga ma carbides olimba muzitsulo zachitsulo. Ma carbides awa ndi osagwirizana kwambiri ndi kuvala ndi kutentha, kulola chitsulo chothamanga kwambiri kuti chikhalebe chochepetsera ngakhale chitakhala ndi kutentha kwakukulu ndi kukangana pakupanga makina.

Chinthu chinanso chofunika kwambiri chachitsulo chothamanga kwambiri ndi kulimba kwake komanso kulimba kwake. Mosiyana ndi zida zina zachitsulo, HSS imatha kupirira kugunda kwakukulu komanso kugwedezeka popanda kusweka kapena kusweka. Izi zimapangitsa kuti zikhale zoyenera kwa ntchito zolemetsa zolemetsa pomwe chidacho chimakhudzidwa ndi mphamvu zazikulu pakugwira ntchito.
Kuphatikiza pa mawotchi ake, zitsulo zothamanga kwambiri zimakhalanso ndi makina abwino, zomwe zimalola kuti zikhale zogwira mtima komanso zolondola kupanga ndi kupanga njira. Izi zimapangitsa kuti zikhale zosavuta kwa opanga kupanga mapangidwe ovuta a zida pogwiritsa ntchito HSS, kupanga zida zomwe zimatha kupirira zolimba komanso kumaliza kwambiri.
HSS imadziwikanso chifukwa cha kusinthasintha kwake, chifukwa imatha kugwiritsidwa ntchito popanga zinthu zosiyanasiyana, kuphatikiza chitsulo cha carbon, alloy steel, chitsulo chosapanga dzimbiri, ndi zitsulo zosapanga dzimbiri. Izi zimapangitsa kukhala chisankho chodziwika bwino cha zida zodulira zomwe zimafunikira kugwira ntchito zosiyanasiyana zamakina.

Kuphatikiza apo, HSS imatha kutenthedwa mosavuta kuti ikwaniritse kuuma komwe kumafunikira, kulimba komanso kukana kuvala, kulola kuti zinthu zakuthupi zigwirizane ndi zofunikira zenizeni. Izi kutentha mankhwala kusinthasintha zimathandiza opanga kuti konza bwino ntchito ya HSS kudula zida zinthu zosiyanasiyana Machining ndi zipangizo workpiece.
M'zaka zaposachedwa, kupita patsogolo kwaukadaulo wazitsulo wothamanga kwambiri kwapangitsa kuti pakhale magiredi atsopano azitsulo ndi nyimbo zomwe zimapereka magwiridwe antchito apamwamba. Kupita patsogolo kumeneku kumalola zida zodulira zitsulo zothamanga kwambiri kuti zizigwira ntchito mwachangu komanso kutentha kwambiri, kukulitsa zokolola komanso kupulumutsa ndalama kwa opanga.
Ngakhale kutulukira kwa zida zina monga carbide ndi zoyika za ceramic, chitsulo chothamanga kwambiri chimakhalabe chodziwika bwino pamakina ambiri opangira zitsulo chifukwa cha kuphatikiza kwake koyenera, kutsika mtengo, komanso kugwiritsa ntchito mosavuta. Kukhoza kwake kupirira kutentha kwakukulu, kukhalabe lakuthwa lakuthwa, ndi kukana kuvala ndi kukhudzidwa kumapangitsa kukhala chinthu chodalirika komanso chosunthika cha ntchito zosiyanasiyana zodula ndi makina.
Mwachidule, HSS ndi chinthu chofunika kwambiri pakupanga ndi kuphatikiza kwapadera kwa kuuma, kulimba, kukana kuvala ndi machinability. Kukhoza kwake kuchita bwino pa liwiro lapamwamba komanso kutentha kwambiri kumapangitsa kusankha kofunikira kwa zida zodulira ndi ntchito zina zachitsulo. Ndi kafukufuku wopitilira ndi ntchito zachitukuko, HSS ikuyembekezeka kupitiliza kusinthika kuti ikwaniritse zomwe zikukula zamakina amakono.
