Q: Cov tshuaj muaj pes tsawg leeg ntawm SPCC yog dab tsi?
A: C tsawg dua lossis sib npaug 0.15%, Si Less dua lossis sib npaug li 0.05%, Mn Tsawg dua lossis sib npaug 0.50%, P Tsawg dua lossis sib npaug 0.035%, S Tsawg dua lossis sib npaug 0.035%, qis carbon, tsawg sulfur, thiab phosphorus tsawg.
Q: Dab tsi yog cov khoom siv kho tshuab ntawm SPCC?
A: Tensile zog 270-410MPa; Yield zog Ntau dua los yog sib npaug rau 180MPa (tsis yog yuav tsum tau los ntawm JIS, qee lub tuam txhab muaj kev tswj hwm sab hauv); Elongation Ntau dua lossis sib npaug li 34% (thickness Ntau dua lossis sib npaug li 1.6mm).
Q: Dab tsi yog qhov hardness ntau ntawm SPCC?
A: Annealed xeev HRB 50-70, hardness nws txawv heev nyob ntawm seb tempering, piv txwv li, 1/2 hardness yog kwv yees li HRB 75-85.
Q: Vim li cas SPCC thiaj li yuav tsum tau qib?
A: Txhawm rau tshem tawm cov qoob loo (tiv thaiv stamping slip kab), kho qhov roughness (Ra 0.5-2.0μm), txhim kho phaj zoo, thiab muab kev tiv thaiv xeb luv luv nrog oiling.
Q: Dab tsi yog qhov cuam tshuam ntawm kev sib xyaw ua ke ntawm kev ua haujlwm? A: Ntau tshaj C / Mn piv ua rau muaj zog ntxiv tab sis txo cov yas; Kev sib piv ntau dhau ntawm P / S ua rau txias brittleness / kub brittleness, ua rau stamping nquag tawg, thiab impurities yuav tsum nruj me ntsis tswj.
