NM400 hnav resistant phaj feem ntau muab zoo dua toughness nyob rau hauv tej yam kev mob.
Weldability thiab Fabrication ntawm NM400 vs AR400
Weldability yog tswj hwm los ntawm Carbon Equivalent (CEV).
NM 400:Tej zaum yuav muaj ntau dua Mn / alloying rau toughness, uas tuaj yeem ua kom me ntsis ua ntej ua ntej.
Qauv: AR400Feem ntau nta qis carbon kom yooj yim vuam nyob rau hauv cov txheej txheem khw.
Tsis yog NM400 lossis AR400 tsis yog stainless hlau. Lawv xav tau cov txheej txheem tiv thaiv (thawj xim, hmoov txheej, lossis galvanizing) rau qhov chaw corrosive. Nco tseg:PREN(Pitting Resistance Equivalent Number) tsis muaj feem xyuam rau cov pa roj carbon - qib alloy.

Puas yog NM400 tib yam li Hardox 400?
Tsis yog. lawv yog 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 cov hardness zoo sib xws tab sis sib txawv zeb - mus rau - zeb khoom. Ib txwm 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 cia rau 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.
