Ntawm Gnee Steel, peb muab kev ua haujlwm siab -NM400 hnav resistant phajthiab muaj ntau yam ntawm cov hlau tsis xeb hlau xws li NM450 thiab NM500, tshwj xeeb yog tsim los rau cov xwm txheej hnyav ntawm mining thiab quarrying industries.
NM400 hnav resistant phaj
Peb cov NM series hnav resistant steel daim hlau yog tsim los tiv taus huab cua cuam tshuam thiab zawv zawg abrasion, pab txuas ntxiv cov cuab yeej siv lub neej, txo qis sijhawm, thiab txo nqi ua haujlwm.
Vim li cas Mining Khoom Yuav Tsum NM Series Hnav Resistant Steel Phaj
Cov cuab yeej siv mining ua haujlwm nyob rau hauv tsis tu ncua ntawm cov khoom siv abrasive xws li limestone, hlau ore, thiab thee. Cov pa roj carbon monoxide tsis ua haujlwm sai sai raws li cov xwm txheej no, ua rau muaj kev hloov pauv ntau zaus thiab cov nqi kho mob siab.
Gnee Steel's NM400 steel phaj thiab NM series kev daws teeb meem muab:
- Hardness heev:Los tiv thaiv nto nkag los ntawm cov ntxhia ntse.
- Impact Toughness:Txhawm rau tiv thaiv kev tawg hauv qab hnyav lossis pob zeb ntog.
- Nqi Efficiency:Thaum qhov pib nqis peev ntau dua, qhov kev hloov pauv txuas ntxiv txo qis tag nrho cov nqi ntawm cov tswv cuab.

Puas yog NM400 tib yam li Hardox 400?
Tsis yog. lawv muaj qhov sib piv hauv nominal hardness band (~ 400 HBW) tab sis Hardox® 400 yog cov khoom lag luam muaj npe nrog cov tshuaj chemistry, lav qhov tawv thiab cov ntaub ntawv ntxaws ntxaws los ntawm SSAB. NM400 yog Suav tus qauv qib nrog hardness zoo sib xws tab sis kuj sib txawv zeb-rau- zeb khoom. Ib txwm hais qhia qhov yuav tsum tau muaj kev xeem thiab kev lees txais, tsis yog lub npe qeb xwb.
NM400 puas tuaj yeem welded rau cov qauv hlau?
Yog nrog kev sib tw muab tub lim thiab tsim nyog preheat / thermal tswj. Tsis txhob muaj cov khoom siv hluav taws xob siab thiab txheeb xyuas cov khoom siv nrog cov khoom siv vuam cov lus qhia.
Kuv yuav xaiv li cas ntawm NM400 thiab nyuaj NM450 / NM500?
Xaiv los ntawm hom hnav: rau abrasive zawv zawg hnav NM400 feem ntau txaus; rau abrasive heev, ntev -lub neej xav tau xaiv NM450/NM500 tab sis xav tias yuav nce nqi thiab txo formability.
Puas yog NM400 haum rau cov thoob khib nyiab thiab cov khoom pov tseg?
Yog lawm. dav siv rau cov ntawv thov no; xyuas kom weldability thiab thickness haum rau daim ntawv thov.
NM400 puas tuaj yeem raug nplaim taws txiav thiab drilled?
Yog; siv cov txheej txheem kev lag luam txiav tab sis nco ntsoov ntawm qhov tawv tawv ua rau cov cuab yeej hnav ntxiv.
NM400 yuav tsum khaws thiab tuav li cas?
Khaws ca ntawm cov ntoo, zam kev puas tsuaj ntawm ntug, ua kom huv si thiab tiv thaiv kom tsis txhob muaj kab mob ntawm qhov chaw vuam.
