FAQ

Q1: NM500 sawv cev rau dab tsi? Tus txheej txheem nyob qhov twg?
A: NM stands rau "Nai Mo" - tus pinyin Suav abbreviation rau "wear-resistant." Lub "500" yog hais txog qhov nominal Brinell hardness ntawm ~ 500 HBW. NM500 yog tsim nyob rau hauv Suav teb tus qauv GB / T 24186.

Q2: NM500 piv rau AR500 lossis Hardox 500 li cas?
A: NM500, AR500 (ASTM), thiab Hardox 500 (SSAB) yog cov kev ua tau zoo sib npaug hauv 500 HBW abrasion-cov hlau tiv taus. Tag nrho peb qhov zoo sib xws hardness, hnav tsis kam, thiab lub zog. Qhov sib txawv tseem ceeb yog: cov qauv tsim, tus nqi, thiab muaj cov thickness ntau yam. NM500 muaj kev sib piv ntawm tus nqi qis dua, ua rau nws qhov kev xaiv zoo tshaj rau tus nqi -sensitive B2B buyers.

Q3: NM500 puas tuaj yeem welded?
A: Yog lawm, NM500 muaj qhov zoo weldability muab cov txheej txheem vuam kom raug. Preheating rau 150-200℃thiab siv tsawg-hydrogen consumables (piv txwv li, E11018-M) yog qhov tseem ceeb. Vim nws cov hardness siab, tsis tswj vuam yuav ua rau hydrogen-induced cracking. Nco ntsoov xa mus rau cov txheej txheem vuam tshwj xeeb (WPQ) rau koj daim ntawv thov.

Q4: Puas yog NM500 haum rau txias dabtsi yog khoov?
A: Yog, NM500 tuaj yeem tsim txias. Txawm li cas los xij, vim nws cov hardness siab, cov kws kho mob yuav tsum:

Npaj cov npoo los ntawm kev sib tsoo cov txheej tawv tawv los ntawm cov pa roj- txiav los yog txiav cov npoo.Siv lub vojvoog ntau ntxiv (feem ntau yog 3 × t rau transverse dabtsi yog khoov, 4 × t rau ntev).
