Nanga amanye amanqaku aphambili okwazisa nge440C yentsimbi yentsimbi engatyiwa bar:
1. Ukubunjwa: I-440C ye-stainless steel bar flat ngokuyinhloko yenziwe nge-chromium (16-18%), i-carbon (0.95-1.20%), kunye neemali ezincinci zezinye izinto ezifana ne-manganese, i-silicon, kunye ne-molybdenum.
2. I-Resistance ye-Resistance: I-440C ye-stainless steel bar idume ngokugqwesa kwayo ukuxhathisa, okwenza ukuba ifaneleke kwizicelo ezibandakanya izinto ezixubileyo, izixhobo zokusika, iibheringi, kunye namacandelo angagugiyo.
3. I-Corrosion Resistance: Nangona i-carbon high-carbon steel stainless, i-440C ibonisa ukuxhathisa okulungileyo kokubola.
4. Ukuqina kunye nokuqina: I-440C yentsimbi ye-stainless bar flat inobunzima obukhulu kunye namandla aphezulu, inika ukuqina kunye nokuphila ixesha elide kwizicelo ezifunayo.
