ASTM A871Structcral Steel Platendi mbale ya carbon steel.Matayala a Steel Steel (Zida Zaumisiri Wamakina): Amatanthawuza ku msonkhano wazitsulo womwe umadziwika ndi mphamvu komanso mawonekedwe ake.Formability amasonyezedwa ngati elongation pambuyo yopuma mu kukanika mayeso.Chitsulo chokhazikika chimagwiritsidwa ntchito ponyamula katundu ndi ntchito zina pomwe mphamvu yachitsulo ndi njira yopangira kuti igwiritsidwenso ntchito.Chitsulo chokhazikika ndi mtundu wachitsulo chapadera.Maguluwa ndi awa:
1. Chitsulo chogwiritsidwa ntchito ngati makina osiyanasiyana.Zimaphatikizapo zitsulo zopangidwa ndi carburized, zitsulo zozimitsidwa ndi zowonongeka, zitsulo za masika ndi zitsulo zozungulira.
2. Chitsulo chogwiritsidwa ntchito ngati zomangamanga.Zimaphatikizapo A, B, chitsulo chapadera ndi chitsulo chochepa cha alloy mu carbon steel.

Chitsulo chachitsulo ndi chitsulo chathyathyathya chomwe chimaponyedwa ndi chitsulo chosungunula ndikukanikizidwa pambuyo pozizira.
Chitsulocho ndi chathyathyathya, amakona anayi ndipo chikhoza kugubuduzidwa mwachindunji kapena kudulidwa kuchokera kuzitsulo zazikulu.
Zitsulo zachitsulo zimagawidwa molingana ndi makulidwe, mbale yachitsulo yopyapyala ndi yochepera 4 mm (yochepa kwambiri ndi 0.2 mm), mbale yachitsulo yapakati ndi 4-60 mm, ndi mbale yachitsulo yowonjezera ndi 60-115. mm.
Mapepala achitsulo amagawidwa m'mbale yotentha yotentha ndi mbale yozizira yozungulira molingana ndi kugudubuza.
1. Mbale Yachitsulo Yotentha Yotentha
Njira zowotchera zotentha zimaphatikizapo kugudubuza kotentha, kupangira, kutulutsa ndi njira zina.
2. Cold Anagulung'undisa Zitsulo mbale
Njira zopangira zoziziritsa kuzizira zimaphatikizapo kugudubuza kozizira, kujambula kozizira ndi kujambula kozizira, kupindika kozizira, kutulutsa kozizira ndi njira zina.
The ozizira anagubuduza njira ndi kupitiriza processing otentha adagulung'undisa zitsulo pansi recrystallization kutentha kuti ozizira adagulung'undisa zitsulo.Kugwiritsa ntchito njira yozizira yopukutira kungathe kusintha mawonekedwe achitsulo, ndikupeza zinthu zolondola kwambiri komanso zosalala.
Q: Kodi ndinu wopanga?
A: Inde, ndife opanga Mapepala a Carbon Steel, Tili ndi fakitale yathu, yomwe ili ku Shandong, China.Tili ndi mphamvu zotsogola popanga ndi kutumiza kunja mbale yachitsulo ya kaboni, pepala lozizira lopiringizika, etc. Tikulonjeza kuti ndife zomwe mukuyang'ana.
Q: Kodi tingayendere fakitale yanu?
A: Takulandirani ndi manja awiri tikakhala ndi ndondomeko yanu tidzakutengani.
Q: Kodi muli ndi ulamuliro wabwino?
A: Inde, tikhoza kuvomereza BV, SGS kuyendera kachitatu.
Q: Kodi mungakonze zotumiza?
A: Zedi, tili ndi wotumiza katundu wokhazikika yemwe angapeze mtengo wabwino kwambiri kuchokera kumakampani ambiri oyendetsa sitima ndikupereka ntchito zaukadaulo.
Q: Kodi nthawi yanu yobweretsera imakhala yayitali bwanji?
A: Nthawi zambiri ndi masiku 7-14 ngati katundu ali katundu.kapena ndi masiku 25-35 ngati katunduyo alibe katundu, malinga ndi kuchuluka.
Q: Tingapeze bwanji zopereka?
A: Chonde perekani ndondomeko ya mankhwala, monga zakuthupi, kukula, mawonekedwe, etc.So tikhoza kupereka zabwino kwambiri.
Q:Kodi tingatenge zitsanzo zina? Malipiro aliwonse?
A: Inde, mungapeze zitsanzo zomwe zilipo m'gulu lathu.Kwaulere kwa zitsanzo zenizeni, koma makasitomala ayenera kulipira mtengo wa katundu.
Q: Kodi mumapanga bwanji bizinesi yathu kukhala yayitali komanso ubale wabwino?
A: 1.Timasunga khalidwe labwino komanso mtengo wampikisano kuti tiwonetsetse kuti makasitomala athu amapindula.
2.Timalemekeza kasitomala aliyense monga bwenzi lathu ndipo timachita bizinesi moona mtima ndikupanga mabwenzi nawo, mosasamala kanthu komwe amachokera.
