Cov lus nug nquag nug (FAQ)
JIS G3141 SPCC txias - dov coj mus muag hlau yog dab tsi?
JIS G3141 SPCC yog kev lag luam -qib txias- dov qis- carbon steel txhais los ntawm Japanese Industrial Standards (JIS) G3141. Nws yog ib qho dav - lub hom phiaj steel nrog zoo formability, zoo ib yam ntawm cov nto zoo, thiab tus nqi -effectiveness, dav siv nyob rau hauv ntau yam fabrication thiab manufacturing industries.
Dab tsi yog qhov txawv ntawm SPCC thiab SPCC-SD?
SPCC yog qib pib ntawm JIS G3141 txias- dov ua lag luam hlau, thaum SPCC-SD yog qib - qib nrog dull (matte) nto tiav. SPCC-SD yog optimized rau txheej thiab plating vim nws tswj qhov chaw roughness, thaum SPCC tuaj yeem muaj qhov sib txawv ntawm qhov tiav (xws li, ci tiav SPCC-SB).
Puas yog JIS G3141 SPCC steel muaj qhov zoo weldability?
