| Tensile zog | 950-1100 MPa |
| Elongation | Ntau dua lossis sib npaug li 12% |
Xav txog cov tshuaj muaj pes tsawg leeg ntawm NM400
Cov tshuaj muaj pes tsawg leeg txiav txim siab hnav tsis kam thiab weldability:
| Element | Cov ntsiab lus (%) |
|---|---|
| C (Carbon) | 0.12 – 0.20 |
| Manganese (Mn) | 1.20 – 1.70 |
| Si (Silicon) | 0.80 – 1.20 |
| P (phosphorus) | Tsawg dua lossis sib npaug li 0.025 |
| S (Sulfur) | Tsawg dua lossis sib npaug li 0.015 |
| Cr / Nia | Tsawg dua los yog sib npaug li 0.30 |
Daim ntawv thov ntawm NM400
NM400 yog haum rau nruab nrab-rau- hnyav hnav daim ntaub ntawv. Cov ntawv thov ib txwm muaj xws li:
Mining thoob, chutes, thiab hoppers
Kev tsim kho tshuab hniav thiab hnav qhov chaw
Crusher liners thiab conveyor Cheebtsam
Cov tsheb thauj khoom pov tseg thiab hnyav - lub luag haujlwm trailer
Rau abrasive heev lossis siab - daim ntawv thov cuam tshuam, koj tuaj yeem xav txog NM450 lossis NM500 hloov NM400.
Ntsuas phaj Thickness thiab qhov loj ntawm NM400
NM400 steel phaj muaj nyob rau hauv cov thicknesses sib txawv kom phim cov khoom siv:
| Thickness | Dav | Ntev |
|---|---|---|
| 4-25 hli | 1000-2500 hli | 2000-12000 hli |
Pro cov lus qhia: Cov phaj tuab ua kom muaj zog tab sis yuav tsum tau tshwj xeeb vuam thiab tsim cov txheej txheem.
Thaum xaiv NM400 steel daim hlau, tsom rau:
- Mechanical zog uas phim koj hnav thiab cuam tshuam kev xav tau
- Tshuaj muaj pes tsawg leeg rau weldability thiab toughness
- Phaj thickness haum rau koj cov khoom siv
- Kev ntseeg tau ntawm tus neeg siv khoom los xyuas kom meej qhov zoo ib yam
Txiav txim koj NM400 abrasion-resistant steel phaj hnub no kom txo tau hnav, downtime, thiab tu nqi.

NM400 steel yog dab tsi?
NM400 steel yoglub siab -lub zog, hnav- cov hlau tsis muaj zog paub txog nws qhov zoo dua durability thiab toughness. NM400 yog Suav GB tus qauv steel qib. NM 400 cov khoom siv dav siv hauv kev lag luam uas tiv thaiv kev puas tsuaj yog qhov tseem ceeb, xws li hauv kev tsim kho thiab mining sectors.
Qhov txawv ntawm Hardox 400 thiab NM400 yog dab tsi?
Hardox 400 feem ntau muaj ntau dua chromium (Cr) thiab npib tsib xee (Ni) cov ntsiab lus, uas ua rau kom zoo dua hardness thiab toughness, thaum NM400 tswj qhov sib npaug ntawm tus nqi thiab kev ua haujlwm.
Qhov txawv ntawm AR 400 thiab NM400 yog dab tsi?
NM400 muab tus nqi- ua haujlwm tau zoo thiab qis- qhov kub thiab txias, ua rau nws zoo tagnrho rau kev siv nyiaj- cov phiaj xwm nco qab nyob rau hauv ib puag ncig hnav. AR400, nrog nws cov kev cuam tshuam zoo tshaj plaws thiab kev tsim qauv, ua tau zoo nyob rau hauv siab - cov ntawv thov cuam tshuam uas xav tau kev tsim khoom.
NM400 puas tuaj yeem rov ua kom sov lossis cua sov-kho thaum ua haujlwm?
Qhov no yog ib qho ntawm cov lus ceeb toom tseem ceeb tshaj plaws rau thawj - cov neeg siv sijhawm.
NM400 steel phaj yuav tsum tsis txhob dhau qhov siab siab -kev kho cua sov. Cov khoom ua tiav nws cov kev hnav tsis kam los ntawm kev quenched thiab tempered (Q + T) txheej txheem. Yog tias rov ua kom qhov kub thiab txias -xws li nplaim hluav taws kub kom yooj yim khoov- lub microstructure sab hauv yuav raug hloov, uas ua rau poob mus tas li ntawm hardness thiab hnav tsis kam.
Tsis tas li ntawd, qhov pom zoo qhov kev pabcuam kub rau NM400 feem ntau qis dua 250℃-300 degree. Tshaj qhov ntau yam no tuaj yeem txo nws cov khoom siv tshwj xeeb tshwj xeeb yog cov qib alloyed tshwj xeeb (nrog cov ntsiab lus zoo li Mo lossis V) siv.
