Mawonekedwe
Kuuma kwakukulu:Malo ogwirira ntchito a mutu wa nyundo ali ndi kuuma kwa HB300-400, komwe kungathe kukana kuvala ndi kung'ambika.
Kulimba mtima:Malo opangira dzenje la mutu wa nyundo ali ndi kuuma kwa HB550-600, komwe kumakhala ndi kulimba kwabwino kuti zisawonongeke.
Moyo wautali wautumiki:Mutu wa nyundo umakhala ndi moyo wautali wautumiki, womwe ndi nthawi 2-2.5 kuposa chitsulo cha manganese.
Mapulogalamu
nyundo yathu yotsika ya alloy medium carbon steel dual hardness nyundo imagwiritsidwa ntchito kwambiri pokonzanso zitsulo, kuphwanya mphira, mafakitale obwezeretsanso magalimoto. Ndizoyenera kuphwanya ndikupera zida zosiyanasiyana zolimba, monga mbale yachitsulo, mphira, nkhuni, mbale za aluminiyamu, etc.
Ubwino wake
Kuchita kwakukulu: Mutu wa nyundo umaphatikiza ubwino wa kuuma kwakukulu ndi kulimba kwambiri.
Moyo wautali wautumiki: Mutu wa nyundo uli ndi moyo wautali wautumiki.
Ntchito zambiri: Mutu wa nyundo umagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana.
Mapeto
nyundo yathu yotsika ya alloy medium carbon steel ndi chinthu chapamwamba kwambiri chomwe chimalandiridwa bwino ndi makasitomala. Ndi chisankho chabwino kwa makasitomala omwe amafunikira mutu wa nyundo wokhala ndi ntchito zapamwamba komanso moyo wautali wautumiki.
