Yintoni i-Low Carbon Steel?

Intsimbi ekhabhoni ephantsi, eyaziwa ngokuba yintsimbi ethambileyo, yenye yezona ntlobo zentsimbi ezisetyenziswa kakhulu ehlabathini. Ukuguquguquka kwayo, ukufikeleleka kwayo, kunye noluhlu olubanzi lwezicelo ezenza ukuba ibe yinto ebalulekileyo kumashishini afana nokwakha, iimoto, imveliso, kunye noomatshini. Ukuze siqonde ngcono indima yayo, eli nqaku libonelela ngesishwankathelo esipheleleyo sokuba yintoni intsimbi ekhabhoni ephantsi, ukwakheka kwayo, iimpawu zayo, iingenelo, kunye nokusetyenziswa okuqhelekileyo.

Inkcazo yeNsimbi ePhantsi kweKhabhoni

Intsimbi yekhabhoni ephantsi luhlobo lwentsimbi yekhabhoni enomxholo wekhabhoni ophantsi, oqhele ukuba phakathi kwe-0.05% kunye ne-0.25%. Umxholo wekhabhoni ophantsi wenza le ntsimbi ithambe, ithambile ngakumbi, kwaye kube lula ukusebenza ngayo xa ithelekiswa neentsimbi zekhabhoni eziphakathi okanye eziphezulu. Idla ngokubizwa ngokuba “yintsimbi ethambileyo” ngenxa yamandla ayo athambileyo xa ithelekiswa neentsimbi eziqinileyo.

Ukwenziwa kweeKhemikhali

Ukwakhiwa kwentsimbi enekhabhoni ephantsi kudla ngokubandakanya:
