Dab tsi yog qhov tshwj xeeb hardness qhov tseem ceeb rau SPCC cov ntawv?
A: 1/8 Hard: HRB 50-71, HV 95-130; 1/4 Hard: HRB 65-80, HV 115-150; 1/2 Hard: HRB 74-89, HV 135-185; Hard: HRB Ntau dua lossis sib npaug rau 85, HV Ntau dua lossis sib npaug rau 170; Tus Qauv Zauv: HRB 85-110.
Dab tsi yog qhov sib txawv ntawm qhov tiav rau SPCC cov ntawv?
A: Lawv raug faib ua matte (D) thiab glossy (B). Lub matte tiav yog tiav los ntawm kev txhaj tshuaj peening cov yob tom qab sib tsoo, thaum lub glossy tiav tiav los ntawm precision sib tsoo cov yob.
Dab tsi yog cov qhab nia zoo rau SPCC cov ntawv?
A: Cov no suav nrog FB (siab dua- qib tiav nto) thiab FD (ultra- siab- qib tiav), thiab lwm yam. FB tso cai rau me me tsis xws luag uas tsis cuam tshuam rau kev tsim thiab txheej adhesion; FD yog qhov zoo dua, nrog rau ib sab tsis muaj qhov tsis xws luag cuam tshuam rau lub ntsej muag txheej, thiab sab nraud tsawg kawg ua tau raws li FB cov qauv.
Puas yog SPCC daim ntawv tuaj yeem xeb?
A: Yog, nws yooj yim rau xeb. Vim tias nws tsis tshua muaj -cov pa roj carbon txias- dov hlau tsis muaj txheej tiv thaiv, nws yooj yim oxidized thiab xeb thaum raug rau qhov chaw ntub dej, feem ntau yuav tsum tau kho saum npoo xws li electroplating lossis txau.
Puas yog SPCC daim ntawv haum rau stamping?
A: Yog. Nws muaj cov ntsiab lus carbon tsawg, zoo plasticity thiab formability, tab sis ntau manganese cov ntsiab lus los yog cov txheej txheem kub dov tsis zoo tuaj yeem ua rau txo elongation, ua rau nws yooj yim tawg thaum lub sij hawm stamping.
