Q: Dab tsi yog SPCC coil?
A: SPCC yog qhov txias- dov qis- carbon steel coil ua raws li tus qauv Japanese JIS G3141. Nws yog tsim los ntawm kub- dov steel strip los ntawm txias dov, hais txog kev ua haujlwm txias thiab qhov chaw zoo. Nws yog feem ntau siv nyob rau hauv stamped qhov chaw, hluav taws xob / khoom vaj tse, thiab lwm yam.
Q: Dab tsi yog tag nrho cov cai rau SPCC?
A: Cov qauv qauv yog SPCC - [Quenching thiab Tempering Degree] [Surface Condition], xws li SPCC - SB: S=Standard Quenching thiab Tempering (Annealed + Leveling), B=Ci ntsa iab; Quenching thiab Tempering Degrees suav nrog A (Annealed nkaus xwb), 1/8 Hard, 1/4 Hard, 1/2 Hard, 1 Hard; Cov xwm txheej saum npoo yog B (Zoo) thiab D (Nqaij).
Q: Cov qauv hauv Suav teb twg / cov qauv European / Asmeskas cov qauv SPCC cuam tshuam li cas?
A: National Standard ≈ GB/T 11253 Q195/Q215; European Standard ≈ EN 10130 DC01; American Standard ≈ ASTM A1008 CS Hom B.
Q: Dab tsi yog qhov tseem ceeb ntawm cov qauv kev ua haujlwm ntawm SPCC coils?
A: JIS G3141 qhia txog cov tshuaj muaj pes tsawg leeg (C Tsawg dua lossis sib npaug rau 0.12%, Mn Tsawg dua lossis sib npaug 0.50%, P / S Tsawg dua lossis sib npaug rau 0.035%), cov khoom siv dag zog (lub zog tensile 270-410MPa, yield zog ntau dua lossis sib npaug rau 180MPa ntau dua), nto/dimensional tolerances, thiab quenching thiab tempering.
Q: Qhov txawv ntawm SPCC, SPHC, thiab SPCD yog dab tsi?
A: SPHC=kub- dov substrate, SPCC=txias- dov cov khoom tiav, SPCD=txias- dov sib sib zog nqus- kos qib (zoo plasticity dua SPCC).
