Uqinisekiso lokwenyani lomgangatho wombhobho wentsimbi ye-ST52
Intsimbi engeyiyo i-alloy ithathwa njengentsimbi yolwakhiwo oluqhelekileyo, olubonakaliswa ngamandla okuqina kunye nenqaku lesivuno. Isetyenziswa kulwakhiwo loluntu, ubunjineli obuphantsi komhlaba, ubume bebhulorho, ulwakhiwo lwaselwandle, ukwenziwa kweekhonteyina, ukwenziwa kweemoto kunye noomatshini.
Ibakala lensimbi ngokuqhelekileyo liqulunqwe ileta st, ixabiso leempawu zentsimbi kunye nesalathisi somgangatho. Umzekelo, iSt52-3. Kwinqanaba lensimbi kunye neemfuno ezithile zokukhetha indlela ye-deoxidation, uphawu oluhambelanayo (U okanye R) lubekwe phambi kwebakala lensimbi.
Umzekelo: ust37-2 okanye rst37-2
Uhlobo oluncinci lwe-st37-2 st37-3u st37-3n luthatha indawo yentsimbi engama-20
I-St37 luphawu lwaseJamani, kodwa luphawu ngokubanzi kunye neebrendi ezincinci eziliqela.
Njenge st37-2, st37-3u, st37-3n, rst-2, ust37-2, njl.
I-St37-2 yi-brand ye-carbon structural steel eJamani
Esi sixhobo silingana ne-carbon structural steel Q235B (inombolo ye-brand endala: a3-b) e-China.
Ukongeza, ngenxa yokuba le ntsimbi ifana nentsimbi yaseChina ephezulu ye-carbon structural steel 20, inokuthi ithathelwe indawo yintsimbi engama-20.
Umbhobho wensimbi ongenamthungo ophakamileyo kunye nombhobho webhoyila woxinzelelo oluphezulu luhlobo lwebhoyila yombhobho, oyinxalenye yodidi lombhobho wentsimbi ongenamthungo. Indlela yokuvelisa iyafana neyombhobho ongenamthungo, kodwa kukho iimfuno ezingqongqo kwibakala lensimbi elisetyenziselwa ukwenziwa kombhobho wensimbi. Iityhubhu zebhoyila ezinoxinzelelo oluphezulu zihlala zisetyenziswa phantsi kobushushu obuphezulu kunye neemeko zoxinzelelo oluphezulu. Iityhubhu zebhoyila ezinoxinzelelo oluphezulu zisetyenziswa ikakhulu ukwenza iityhubhu zokufudumeza, iityhubhu zokufudumeza, iityhubhu zomoya, iityhubhu eziphambili zomphunga, njl.
