Umbhobho we-Carbon steel seamless (umbhobho we-cs smls) ngumbhobho omde wentsimbi onecandelo elinomngxuma kwaye akukho malungu ajikeleze kuwo; isetyenziswa kakhulu ekuthuthweni kweoli, igesi yendalo, igesi, amanzi kunye nokuthuthwa kwezinto ezithile eziqinileyo. Xa kuthelekiswa neminye imibhobho yentsimbi, umbhobho we-cs ongenamthungo unenzuzo eyomeleleyo ekuxhathiseni ukugoba; kwaye ubunzima bombhobho we-cs ongenamthungo bulula ngokwentelekiso, eyintsimbi yecandelo elinoqoqosho kakhulu.

Izinto ezilungileyo ze-cs imibhobho yentsimbi engenamthungo:

1. Umbhobho wensimbi ongenamthungo unobunzima obunzima, kuphela i-1/5 yentsimbi yesikwele, ngoko inokusebenza kakuhle kobunzima bokukhanya.
2. Ukuxhatshazwa kwe-Corrosion kwimibhobho yensimbi engenamthungo: i-asidi, i-alkali, ityuwa kunye nokusingqongileyo kwe-atmospheric, ukumelana nokugqwala, ukumelana nokushisa okuphezulu, ukuchasana kwempembelelo, ukumelana nokukhathala, akukho mfuneko yokugcinwa rhoqo, kunye nobomi benkonzo iminyaka engaphezu kwe-15;
3. Amandla okuqina kombhobho wensimbi engenamthungo ngamaxesha angama-8-10 aphezulu kuneyentsimbi eqhelekileyo, kwaye imodyuli yayo e-elastic ingcono kuneyentsimbi, enokumelana nokunyuka okugqwesileyo, ukuxhathisa ukubola kunye nokuchasana kwempembelelo;
4. Umbhobho wentsimbi ongenamthungo uneempawu ezigqwesileyo zoomatshini kunye nokusebenza ngokulula;
5. Umbhobho wensimbi ongenamthungo une-elasticity ephezulu, isetyenziselwa izixhobo zemishini, ayinayo inkumbulo, i-deformation, kunye ne-anti-static.

Ububi bemibhobho yentsimbi engenamthungo ye-cs:

1. Kufuneka sazi ukuba ubukhulu bodonga lwensimbi engenamthungo ekumgangatho ophezulu buya kuba buninzi kakhulu, kuba ubuninzi bodonga lwemveliso, lunoqoqosho ngakumbi kwaye lusebenza. Ukuba ubukhulu bodonga buncinci, iindleko zayo zokucubungula ziya kunyuka kakhulu. Ubukho bezibonelelo bonyusa iindleko zezibonelelo.
2. Inkqubo yensimbi engenamthungo iphinda inqume imida yayo. Isinyithi esiqhelekileyo esingenamthungo sinokuchaneka okuphantsi, ubukhulu bodonga olungalinganiyo, ukukhanya okuphantsi ngaphakathi nangaphandle kombhobho, ixabiso eliphezulu lobude obusisigxina, ukugoba kunye namabala amnyama ngaphakathi nangaphandle. Ukususa akukho lula;

3. Ukufunyaniswa kunye nokubunjwa kwayo kufuneka kuqhutywe ngaphandle kweintanethi. Ngoko ke, iquka ukugqwesa kwayo kwi-high-pressure, high-high-power, i-mechanical structural materials.
