Lub ntsiab series ntawm txias dov tuag steel yog siab hardness txias ua hauj lwm hom, uas yog tsuas yog siv rau tuag yuav tsum tau siab compression kuj thiab hnav tsis kam. Lub hardness siab dua HRC 60-62. Lub hardness ntawm cov tuag yuav tsum muaj kev cuam tshuam resistant thiab siab toughness yog qis dua HRC 60 - 62. Chav S thiab qee chav A thiab feem ntau quenched thiab tempered steel, caij nplooj ntoos hlav steel, kub ua hauj lwm tuag los yog lub hauv paus hlau yog tsuas yog siv. Rau loj stamping tuag, xws li tsheb sab nraud stamping qhov chaw, cam khwb cia hlau yog tsuas yog siv. Zinc puag alloy lossis cov khoom siv polymer sib xyaw yog siv rau lub neej yooj yim lossis me me.
Daim ntawv thov kev kub ceev steel thiab ultra-siab ceev steel nyob rau hauv txias ua hauj lwm tuag yog loj hlob sai heev. Nws feem ntau yog vim qhov siab "compressive zog / hardness" piv. Lub hardness tuaj yeem xaiv los ntawm HRC60-70.
Hmoov tuag steel muaj kev hnav zoo heev lub neej, hardness tsis siab HRC 60-62, thiab yog siv dav.
Cov cuab yeej carbon hlau tseem muaj qee qhov kev thov ntau yam hauv cov punch lossis cov khoom muag muag stamping tuag nrog lub neej ntawm 100000 daim.
