Dab tsi yog NM400 Hnav Resistant Steel Phaj?
NM 400yog lub siab -lub zog hnav- steel phaj. Nws lub npe muab los ntawm lub npe ntawm Suav pinyin rau "hnav tsis kam". Tus naj npawb 400 yog hais txog nws qhov kev ntsuam xyuas Brinell hardness, nrog rau saum npoo hardness xws li360-450 HB. Nws lub zog txhua yam yog 3 mus rau 5 npaug ntawm qhov zoo tib yam qis- alloy steel daim hlau, thiab nws tau nkag rau hauv qhov kub thiab txias.
Lub neej kev pab cuam ntawm NM400 hnav-cov phaj steel tsis ruaj khov, uas feem ntau yog nyob ntawm qhov chaw pabcuam thiab cov txheej txheem tsim khoom. Txhawm rau txuas ntxiv nws lub neej kev pab cuam, kev tiv thaiv kev tiv thaiv - kev kho corrosion yog nqa tawm ntawm ob qho tib si sab nrauv thiab sab hauv ntawm NM400 hnav- cov phaj steel resistant.
Tiv tauj peb tam sim no rau tus nqi tshiab tshaj tawm rau NM400.
NM400 is rated at approximately 360–440 HBW (Brinell Hardness). If the material being processed is significantly harder than the plate, or subjected to extreme continuous impact, wear will accelerate. For these heavy-duty scenarios, upgrading to a harder plate like NM500feem ntau yuav tsum tau.
Fabrication thiab Vuam:
Kev vuam tsis zoo los yog txiav-xws li ua tsis tau preheat cov hlau lossis siv cov khoom siv hluav taws xob tsis raug- tuaj yeem ua rau lub phaj kub hnyiab tau- thaj tsam cuam tshuam (HAZ), ua rau ua tsis tiav ntxov.
Abrasion vs. Impact:
NM400 muab qhov sib npaug zoo ntawm ob qho tib si. Txawm li cas los xij, qhov cuam tshuam loj heev (xws li cov pob zeb ncaj qha ntawm cov pob zeb hnyav) yuav degrade nws sai dua li cov xuab zeb dawb huv (xws li cov xuab zeb zoo).
Yam dab tsi yuav cuam tshuam rau tus nqi hnav?
