◦ Umgangatho wokusetyenziswa: GB/T1222-2007.
◦ Ubuninzi: 7.85 g/cm3.
• Ukwakheka kweekhemikhali
◦ Ikhabhoni (C): 0.62%~0.70%, enika amandla asisiseko kunye nokuqina.
◦ IManganese (Mn): 0.90% ~ 1.20%, nto leyo ephucula ukuqina kwayo kwaye iphucula ukuqina kwayo.
◦ I-Silicon (Si): 0.17%~0.37%, nto leyo ephucula ukusebenza kokucutshungulwa kunye nokucocwa kweenkozo.
◦ I-Phosphorus (P): ≤0.035%, i-sulfur (S) ≤0.035%, ilawula ngokungqongqo ukungcola.
◦ I-Chromium (Cr): ≤0.25%, i-nickel (Ni) ≤0.30%, i-copper (Cu) ≤0.25%, izinto ezidibanisa ukulandelelana, ezinceda ekuphuculeni ukusebenza.
• Iimpawu zoomatshini
◦ Amandla aphezulu: Amandla okutsalwa kwe-σb yi-825MPa~925MPa, kwaye ezinye iinkcukacha zingaphezulu kwe-980MPa. Inomthamo obalaseleyo wokuthwala kwaye ifanelekile kwiimeko zoxinzelelo oluphezulu.
◦ Ukuqina okuhle: Inomda ophezulu wokunwebeka, inokumelana nokuguquguquka okukhulu kokunwebeka ngaphandle kokuguquka okusisigxina, kwaye inokugcina nokukhulula amandla ngokuchanekileyo.
◦ Ubunzima obuphezulu: Emva konyango lobushushu, inokufikelela kwi-HRC50 nangaphezulu, inokumelana nokuguguleka okukhulu, ifanelekile kwiimeko zokuguguleka.
◦ Ukuqina okuhle: Xa ithwaxwa yimithwalo eyoyikekayo, inokufunxa amandla athile ngaphandle kokuqhekeka okubuthathaka, nto leyo ephucula ukuthembeka kunye nobomi benkonzo phantsi kweemeko ezinzima.
• Iimpawu
◦ Ukuqina okuphezulu: I-Manganese iphucula kakhulu ukuqina, ifanelekile ekuveliseni izipringi kunye neendawo ezinkulu ezinobubanzi obungaphezulu kwe-20mm.
◦ Ukungaguquguquki komphezulu: Umgangatho womphezulu uzinzile ngexesha lonyango lobushushu, nto leyo enciphisa umngcipheko wokungaphumeleli kwangethuba.
◦ Ubushushu obugqithisileyo kunye nokubuthathaka kobushushu: Ubushushu bokucima kufuneka bulawulwe ngokungqongqo, kwaye uludwe lobushushu obubuthathaka kufuneka luphetshwe ngexesha lokufudumala.
◦ Ukusebenza kakuhle kokucubungula: ingenziwa ngesinyithi kwaye idityaniswe, ifanelekile ukuvelisa iindawo ezimile okwe-complex, kodwa i-cold deformation plasticity iphantsi.
• Iinkcukacha zonyango lobushushu
◦ Ukucima: Ubushushu bokucima buyi-830℃±20℃, ukupholisa ioyile.
◦ Ukufudumala: Ubushushu bokufudumala 540℃±50℃, ±30℃ xa kukho iimfuno ezikhethekileyo.
◦ Ukulungisa: Ubushushu 810±10℃, ukupholisa umoya.
• Iindawo zokusetyenziswa
◦ Ukwenziwa kwentwasahlobo: njengeentwasahlobo zamagqabi eemoto, iintwasahlobo ezifunxa umbane, iintwasahlobo zevalvu, iingcongolo ze-clutch, njl.
◦ Izixhobo zoomatshini: zingasetyenziselwa ukuvelisa izixhobo ezinomthwalo omninzi, ezidityaniswe kakhulu ezifana neegiya, iibheringi, kunye neepiston.
◦ Izixhobo zokusika kunye nee-stamping dies: ngokusebenzisa ubulukhuni bayo obuphezulu kunye nokumelana nokuguguleka, ingasetyenziselwa ukwenza izixhobo zokusika, ii-stamping dies, njl.njl.
◦ Izakhiwo neebhulorho: zingasetyenziselwa ukuvelisa izinto eziphucula amandla okuthwala kwezakhiwo, ezifana neebheringi zebhulorho, izixhasi zesakhiwo, njl.
