Tus kab mob spcyog Ameslikas tus qauv Japanese (JIS) "kev siv dav davCold Rolled Carbon Steel Ntawvthiab Sawb "Steel npe, tam sim no ntau lub teb chaws lossis cov lag luam tau siv cov qauv hlau thiab cov qauv zoo sib xws. Nco ntsoov cov ntawv sib txuas hlau), SPCE (txias-rolled carbon steel ntawv thiab Sawb rau kev sib sib zog nqus duab), SPCCK \ SPCCCE, thiab lwm yam lwm yam), ntsig txog, rau cov sijhawm sib txawv.

2 Cheebtsam
Japanese hlau (JIS series) nyob rau hauv qib ntawm cov txheej txheem zoo tib yam nkaus yog muaj peb ntu ntawm cov khoom, xws li: tias cov hlau, f (ferum) uas cov hlau; Qhov thib ob ntawm cov qauv sib txawv, hom, thiab siv, xws li p (phaj) uas lub raj, kogu) tias lub cuab tam; Qhov thib peb ntawm cov yam ntxwv ntawm tus lej, feem ntau qhov tsawg tshaj plaws lub zog. Feem ntau qhov tsawg kawg tensile lub zog. Xws li: SS400 - thawj tus thawj s spir steel (steel), tus thib ob hais tias "tus qauv" (qauv tag nrho, cov qauv sib txawv ntawm 400MPA rau cov qauv hlau nrog lub tensile Lub zog ntawm 400MPA.

Ntxiv: SpCC - Txias Rolled Carbon Steel Ntawv thiab Sawb Rau Kev Siv Dav, Sib npaug rau Tuam Tshoj Q195-2155 Qib. Tus thib peb tsab ntawv c yog ib tug tsiaj ntawv luv rau txias txias. Yuav tsum tau ua kom ntseeg tau tias qhov kev kuaj tensile, thaum kawg ntawm qib ntxiv t rau SPCCT.

Cov xwm txheej cua sov: A-annealed, s-annealed + tiaj, 8- (1/4) nyuaj, 2- (1/2) nyuaj, 1-nyuaj.

Cov teeb duab theem kev ua tau zoo: zf- rau xuas nrig ntaus ntu nrog cov duab nyuaj tshaj plaws nrog cov duab sib tshooj nrog cov duab sib xyaw nrog cov duab kos nyuaj.

Cov xwm txheej ua tiav deg: D - npub (qaws ua los ntawm sib tsoo cov tshuab sib tsoo), B - Qaws saum npoo av (yob cov txheej txheem los ntawm sib tsoo tshuab).

Cov Khoom Zoo: FC-siab heev tiav nto, FB-siab dua tiav nto. Mob, qhov chaw ua tiav nteg, kev tsim qauv saum npoo av (rau SPE nkaus xwb), qhov loj me (tuab thiab / lossis dav, tsis sib xws).
