Low Carbon Steel Strip
Bann asye ki ba kabòn se yon pwodwi asye ki gen yon kontni kabòn ki ba, anjeneral ant 0.05% ak 0.25%, e li gen ekselan plastisit, severite, ak pèfòmans soude. Pwosesis pwodiksyon li yo gen ladan woule cho, woule frèt, recuit ak lòt etap, pami ki asye a nwa ak briyan teren apre woule frèt gen yon sifas ki lis ak presizyon dimansyon segondè, epi li se lajman ki itilize nan jaden tankou transpò tren, dekorasyon bilding, ak fè tiyo estriktirèl.
Karakteristik yo nan ti -Kabon Steel Strip enkli:
1) bon pèfòmans pwosesis, fasil Stamping, koube ak soude;
2) Segondè balans ant fòs ak duktilite;
3) Gen tretman sifas divès kalite ki ka te pote soti pou pwosesis ki vin apre tankou galvanize ak kouch koulè.
