Lub hardness ntawm S890QL yog dab tsi?
S890QL yog ib qho ntxiv - siab - lub zog cov qauv hlau paub rau nws cov khoom muaj zog (tsawg kawg 890 MPa) thiab toughness tom qab quenching thiab tempering, tab sis nws cov hardness tshwj xeeb (Brinell los yog Rockwell) txawv nrog thickness, feem ntau ntog nyob rau hauv ntau yam ntawm 290{90 Hll thickness, Brinell) (txawm hais tias tus qauv hardness) nws yog qhov zoo dua txhais los ntawm nws lub zog thiab kev cuam tshuam cov khoom es tsis yog ib tus lej hardness. Thaum lub cuab yeej hlau zoo li CPM S90V tej zaum yuav muaj ~ 56-59 HRC, S890QL yog cov qauv hlau, tsom rau qhov muaj peev xwm thauj khoom.
S890QL yog dab tsi?
S890QL yog lub siab- lub zog steel uas ua tau zoo ntawm qhov kub thiab txias, nrog rau nws "L" lub ntsiab lus nws tau teev qhov tsawg kawg nkaus lub zog ntawm qhov kub thiab txias, feem ntau -40℃(-40℃F), yuav tsum muaj tsawg kawg yog 30 Joules ntawm lub zog nqus rau thicknesses txog 50mm, ua rau nws zoo tagnrho rau cov huab cua txias.
Dab tsi yuav tsum tau ceev faj thaum vuam S890QL?
Thaum vuam S890QL (siab- lub zog, quenched & tempered steel), kev ceev faj tseem ceeb muaj xws li kev tswj cov cua sov, tswj cov hydrogen kom tiv thaiv kev tawg, siv qis - hydrogen consumables, ua kom qeeb, tswj kom txias, thiab siv cov kev sib koom ua ke kom haum -nce, tag nrho cov txheej txheem kom khaws cov cua sov kom zoo. hlau.
