Tsawg Carbon Steel Sawb
Tsawg carbon steel sawb yog cov khoom siv hlau uas muaj cov ntsiab lus carbon tsawg, feem ntau ntawm 0.05% thiab 0.25%, thiab muaj cov yas zoo heev, tawv, thiab kev ua haujlwm vuam. Nws cov txheej txheem tsim muaj xws li kub dov, txias dov, annealing thiab lwm theem, ntawm cov dub thiab glossy strip steel tom qab txias dov muaj ib tug du nto thiab siab qhov tseeb, thiab yog dav siv nyob rau hauv teb xws li kev tsheb ciav hlau, lub tsev kho kom zoo nkauj, thiab structural yeeb nkab ua.
Cov yam ntxwv ntawm qis-Carbon Steel Sawb suav nrog:
1) kev ua haujlwm zoo, yooj yim stamping, dabtsi yog khoov thiab vuam;
2) Siab sib npaug ntawm lub zog thiab ductility;
3) Muaj ntau yam kev kho deg uas tuaj yeem ua rau kev ua haujlwm tom ntej xws li galvanizing thiab xim txheej.
