Chitsulo chofewa chimakhala ndi aloyi ya kaboni ya 0,16 mpaka 0.29% motero si ductile.Mipope yachitsulo yofewa imakutidwa ndi mkuwa ndipo motero imapewa dzimbiri, komabe, kusamala kwambiri kuyenera kuchitidwa kuti zisachite dzimbiri.Kuuma kwa chitsulo chochepa kumatha kuonjezeredwa kudzera mu carburizing momwe chitsulo chimatenthedwa pansi pa malo osungunuka pamaso pa chinthu china ndipo kachiwiri pozimitsa, kunja kwa mpweya kumakhala kovuta kwambiri kusunga phata lofewa.Chitsulo chofewa chomwe chimagwiritsidwa ntchito pafupipafupi ndi - A-106 & A-S3.A-106 imabwera pansi pa giredi ya A & B ndipo imagwiritsidwa ntchito pozizira kapena kuwotchera pafupi.

Kupezeka ndi kagwiritsidwe ntchito:
Chitsulo chofewa chimapezeka m'mapangidwe osiyanasiyana omwe amawotcherera mosavuta mu chitoliro, chubu, chubu ndi zina. Mapaipi achitsulo ndi machubu osavuta kupanga, kupezeka mosavuta, komanso otchipa kuposa zitsulo zina.Chiyembekezo cha moyo wazitsulo zoterezi chikhoza kufika zaka 100 ngati chitetezedwa bwino.Mapaipi a Mild Steel ndi machubu amagwiritsidwa ntchito pazolinga zamakina komanso cholinga chaukadaulo komanso uinjiniya.Amagwiritsidwanso ntchito pakumwa madzi akumwa komanso kugwiritsa ntchito chlorination ndi sodium silicate ziletsa dzimbiri mu mipope wofatsa zitsulo.

Mapaipi opangidwa ndi chitsulo chochepa amakhala ndi mpweya wochepera 0.18%, motero samaumitsidwa chifukwa chokhala ndi mpweya wochepa.Chitsulo chofewa chimapezeka m'mapangidwe osiyanasiyana omwe amawotchedwa mosavuta mu chitoliro, chubu, machubu ndi zina. Mipope yachitsulo yocheperako ndi yosavuta kupanga, kupezeka mosavuta, komanso mtengo wocheperapo kusiyana ndi zitsulo zina zambiri.M'malo otetezedwa bwino, moyo wa chitoliro chofewa chachitsulo ndi zaka 50 mpaka 100.

Nthawi zambiri, mapaipiwa amakutidwa ndi zitsulo zina monga mkuwa, kuti atetezedwe ku dzimbiri.Mapaipi a Mild Steel ndi machubu amagwiritsidwa ntchito pazolinga zamakina komanso cholinga chaukadaulo komanso uinjiniya.Amagwiritsidwanso ntchito pakumwa madzi akumwa komanso kugwiritsa ntchito chlorination ndi sodium silicate ziletsa dzimbiri mu mipope wofatsa zitsulo.Kusamala kwambiri kumafunika nthawi zonse kuti mapaipi achitsulo asachite dzimbiri.
