Q195 ua li cas hauv tsheb stamping nyob rau hauv cov nqe lus ntawm cov khoom txias txias?
Elongation ≥33%, tsis muaj qhov tawg tom qab 180 ° txias dabtsi yog khoov, haum rau kev sib sib zog nqus nqus, khoov, thiab hemming, zoo tagnrho rau cov txheej txheem nyuaj xws li lub qhov rooj thiab lub rooj txhawb nqa.
Puas yog qhov weldability ntawm Q195 txhim khu kev qha hauv kev tsim tsheb?
Carbon sib npaug<0.3%, extremely low tendency to weld cracks, suitable for arc welding, laser welding, and resistance welding, with stable joint strength.
Dab tsi yog qhov txawv ntawm txias- dov thiab kub- dov Q195 hauv kev siv tsheb?
Txias- dov: du nto, siab qhov tseeb (± 0.02mm), siv rau lub cev vaj huam sib luag thiab kev txhawb nqa sab hauv.
Kub- dov: tus nqi qis dua, ntau dua thickness, siv rau chassis reinforcements, cov yeeb nkab tso tawm, thiab lwm qhov chaw uas tsis tshua muaj qhov yuav tsum tau ua kom tiav.
Q195 puas tuaj yeem siv rau siab - lub zog tsheb qhov chaw?
Tsis yog. Nrog lub zog tawm los ntawm tsuas yog kwv yees li 195 MPa, qis dua Q235, Q345, lossis siab - lub zog steel feem ntau siv hauv tsheb cov qauv hlau, nws tsuas yog tsim nyog rau cov khoom hnyav hnyav / tsis yog-load{6}} cov kabmob.
Lub hardness ntawm Q195 nyob rau hauv cov khoom siv tsheb li cas?
Txias- cov ntawv dov tuaj yeem hloov kho qhov nyuaj: mos (HRB≤65, sib sib zog nqus nqus), ib nrab- nyuaj (65–80, sib npaug), thiab nyuaj (≥80, cov khoom tsis sib xws).
