Ibha ethe tyaba yentsimbi engagqwaliyo engama-440Cyimveliso yentsimbi engagqwali ekumgangatho ophezulu eyaziwa ngokudibanisa kwayo okugqwesileyo kokuxhathisa ukuguguleka kunye nokuxhathisa ukugqwala. Yeyosapho lwentsimbi engagqwali ye-martensitic kwaye isetyenziswa kakhulu kumashishini ahlukeneyo ngenxa yokusebenza kwayo okugqwesileyo.

Nazi ezinye izinto ezibalulekileyo onokuzisebenzisa ukuze uqalise i-440C stainless steel flat bar:
1. Ulwakhiwo: I-440C stainless steel flat bar yenziwe ikakhulu yi-chromium (16-18%), i-carbon (0.95-1.20%), kunye nezinye izinto ezincinci ezifana ne-manganese, i-silicon, kunye ne-molybdenum.
2. Ukumelana nokuguguleka: I-440C stainless steel flat bar yaziwa ngokuguguleka kwayo okugqwesileyo, okwenza ukuba ifaneleke ukusetyenziswa kwezinto ezirhabaxa, izixhobo zokusika, iibheringi, kunye nezinto ezixhathisa ukuguguleka.
3. Ukumelana Nokugqwala: Nangona iyintsimbi engenasici enekhabhoni ephezulu, i-440C inokumelana nokugqwala okuhle.
4. Ukuqina kunye namandla: I-440C stainless steel flat bar inobunzima obuhle kakhulu kunye namandla aphezulu, inika ukuqina kunye nexesha elide kwizicelo ezifuna amandla.
