Q: Lub npe tag nrho thiab lub ntsiab txhais ntawm SPCC yog dab tsi?
A: SPCC yog cov ntawv luv rau Steel Plate Cold Commercial, xa mus rau dav dav -lub hom phiaj txias- dov carbon steel daim hlau / strips raws li Japanese JIS G3141 tus qauv. Nws yog tsim los ntawm kub -rolled substrate los ntawm txias dov nyob rau hauv chav tsev kub, hais txog qhov zoo nto zoo thiab formability.
Q: Tus qauv tseem ceeb twg SPCC ua raws?
A: Tus qauv tseem ceeb yog Japanese Industrial Standard JIS G3141, "Cold-rolled Carbon Steel Phaj thiab Strips," uas qhia txog nws cov tshuaj muaj pes tsawg leeg, txhua yam khoom, qhov ntev ntev, qhov zoo, thiab lwm yam.
Q: Dab tsi yog cov lus xaus hauv SPCC (xws li SPCC-S, SPCC-1) sawv cev?
A: Lub ntsiab lus qhia txog qib annealing thiab hardness qib: S=annealed, 8=1/8 nyuaj, 4=1/4 nyuaj, 2=1/2 nyuaj, 1=nyuaj, siv los paub qhov txawv ntawm qhov sib txawv thiab qhov sib txawv.
Q: Cov tshuaj muaj pes tsawg leeg ntawm SPCC yog dab tsi? A: C≤0.10%, Si≤0.05%, Mn≤0.50%, P≤0.035%, S≤0.025%, tsawg carbon thiab tsawg silicon tsim los xyuas kom meej cov yas siab.
Q: Dab tsi yog qhov yield zog thiab tensile zog ntau yam ntawm SPCC? A: Tawm lub zog Rel=130–300MPa, tensile zog Rm=270–410MPa, nrog me ntsis sib txawv nyob ntawm qhov hardness qib.
