Daim ntawv thov ntawm NM450 hauv kev ua liaj ua teb machinery kev lag luam
NM450 steel hlauAmeslikas tsim rau tsheb lub cev khoom. Cov hlau no tau nce hardness (thiab yog li tiv thaiv kev puas tsuaj) thaum tuav cov viscosity siab thiab zoo weldability. Niaj hnub no, NM 450 tau siv ntau ntxiv rau lwm lub hom phiaj. Lub hardness ntawm cov khoom ua los ntawm NM 450 steel feem ntau yog los ntawm 410 txog 490HB.

Cov ntawv thov tseem ceeb ntawm NM450 hauv Agricultural Machinery
Grain Harvesting thiab Conveying Equipment
Cov khoom tseem ceeb ntawm kev sau qoob loo thiab cov khoom siv thauj khoom yog nyob rau lub sijhawm ntev - zawv zawg hnav los ntawm cov nplej thiab impurities.NM450 steel phajyog siv rau chutes, ntsia hlau conveyors, thiab liners kom txo tau hnav thiab ntev cov khoom siv lub neej.
Harvester Blades thiab Txiav Bars
Lub tshuab txiav thiab threshing nruas ntawm kev sib xyaw ua ke tau raug cuam tshuam thiab hnav siab ntev ntev.NM450
hlau daim hlauyog siv los tsim cov khoom tseem ceeb no, thiab lawv cov hnav tsis kam thiab lub neej ntev yog 2-3 zaug ntev dua li cov hlau zoo tib yam. Qhov no txhais tau hais tias tus sau qoob loo tuaj yeem ua tiav tag nrho lub caij sau qoob loo yam tsis tau hloov cov hniav.
Rakes thiab Av Npaj Cov Cuab Yeej
Cov qoob loo siv rau tom qab-ploj tillage yuav tsum tiv taus kev puas tsuaj tas li ntawm av thiab pob zeb.NM450 steel phajyog siv los tsim cov hniav harrow thiab harrow thav ntawv, muab kev tiv thaiv zoo heev thaum tuav lub zog zoo.
Plowshares thiab Tillage Tools
CovNM450yog dav siv nyob rau hauv kev tsim cov hydraulic reversible plows thiab siab -ceev adjustable- dav reversible plows. Lub plowshare yog ib feem ntawm kev sib cuag ncaj qha thiab txiav cov av, feem ntau ntsib cov teeb meem nyuaj xws li pob zeb thiab cov hauv paus ntoo. Lub siab hardness thiab hnav tsis kam ntawm lubNM450txuas ntxiv lub neej kev pab cuam ntawm tillage cuab yeej thiab txo downtime rau hloov.
Cov txiaj ntsig ntawm Kev Siv NM450 hauv Agricultural Machinery
| Cov txiaj ntsig | Kev piav qhia |
|---|---|
| Extended Service Life | 3-5 zaug ntev dua li cov qauv hlau zoo li Q345B -2 |
| Txo qhov hnyav | Pab kom 17-24% poob phaus piv rau cov khoom siv tsoos -4 |
| Txo downtime | Kev hloov tsawg dua txhais tau tias muaj sijhawm ntau hauv thaj chaw |
| Cov nqi khiav lag luam qis dua | Tsawg zaus hloov qhov chaw thiab txo cov roj noj |
| Weldability zoo heev | Yooj yim rau fabricate thiab kho siv cov txheej txheem vuam txheej txheem |
NM450 hnav-cov hlau phajtau dhau los ua cov khoom siv tseem ceeb hauv kev tsim cov tshuab ua liaj ua teb niaj hnub. Nws zoo heev hardness, toughness, thiab hnav tsis kam ua rau nws yog ib qho khoom siv zoo tshaj plaws rau cov cuab yeej tillage, cov cuab yeej sau qoob, thiab cov tshuab ua qoob loo.

FAQ:
NM450 steel yog dab tsi?
NM450 yog ib hom kev puas tsuaj -cov hlau phaj uas paub txog nws qhov tshwj xeeb hardness thiab lub zog. Nrog rau Brinell hardness tus nqi ntawm ib ncig ntawm 450 HBW, NM450 abrasion - cov phaj resistant yog engineered los tiv taus hnyav hnyav thaum tuav cov qauv kev ncaj ncees.
NM450 sib npaug li cas?
NM450 yog sib npaug rau cov qib thoob ntiaj teb xws li Hardox 450 (Sweden, SSAB), AR450 (ASTM tus qauv), JFE-EH450 (Nyiv), thiab Dillidur 450V (Lub Tebchaws Yelemees).
Qhov txawv ntawm Hardox 450 thiab NM450 yog dab tsi?
Impact Toughness: Hardox 450 paub txog nws qhov kev cuam tshuam zoo heev, uas tso cai rau nws nqus lub zog yam tsis muaj kev cuam tshuam hauv kev cuam tshuam. NM450 tuaj yeem pom muaj qhov cuam tshuam zoo, tab sis qhov tseeb qhov tseem ceeb yuav txawv nyob ntawm cov chaw tsim khoom thiab kev kho cua sov tshwj xeeb.
