NM500 yog lub zog hnav-resistant steel phaj nrog siab hnav tsis kam, Brinell hardness tus nqi ntawm 500 (HBW) feem ntau yog siv los muab kev tiv thaiv nyob rau hauv lub sij hawm los yog qhov chaw ntawm qhov xav tau kev hnav tsis kam, kom cov khoom siv lub neej ntev, txo kev txij nkawm coj los ntawm kev kho dua tshiab thiab kev poob qis, thiab txo qis kev nqis peev ntawm cov nyiaj.
NM500 steel phaj qib qhia:
"NM": qhia tias hnav-tiv taus phaj "hnav-resistant" pinyin pib;
"500": qhia tias steel phaj 500 yog Brinell hardness nqi ntawm HB nqi;
NM500 steel phaj xa hauv xeev: steel phaj rau tempered (quenched + tempered) lub xeev xa khoom, kuj tuaj yeem raug teev raws li kev xav tau ntawm lub xeev xa khoom.
NM500 steel phaj thickness kev taw qhia kev ua tau zoo: Z15, Z25, Z35.
NM500 steel phaj flaw nrhiav kom tau: ib qho kev sojntsuam, ob qhov kev sojntsuam, peb sojntsuam.
NM500 steel phaj ceev: 7.85 / m3.
Cov txheej txheem ntau lawm: thawj refining → LF refining → VD kho → nruam casting (tuag casting) → tu, cua sov → dov → (stacking) → nto tshuaj ntsuam → batching → flaw detection → tshav kub kho → txiav sampling → kev soj ntsuam → cia.
