Cov yam ntxwv ntawm NM400 Steel Phaj
1. Cold forming (Bending)
- Txawm hais tias NM400 steel muaj hardness siab, nws tuav ruaj khov txias - ua haujlwm.
- Sib tsoo cov npoo ua ntej khoov yog pom zoo
- Pab tiv thaiv ntug tawg
- Xyuas kom smoother kev tshwm sim
2. Kub tsim
- Rau thermal ua ntawm NM400 hnav resistant phaj:
- Pom zoo kub: hauv qab 350 degree
- Yog tias siab tshaj qhov ntsuas kub hloov pauv (Ac), thov:
- Post{0}} tempering: 250℃- 350 degree
Qhov no ua kom cov khoom siv dag zog thiab hardness ntawm NM400 steel phaj nyob ruaj khov. NM400 tso cai rau kev tsim kub ntau dua li qee cov qib European zoo li DILLIDUR 400V.

Cov txiaj ntsig tseem ceeb: Siab hardness + muaj zog cuam tshuam tsis kam=lub neej ua haujlwm ntev dua hauv qhov chaw hnyav.
Hnav Resistance Sib Piv Ntawm Qhov Sib Txawv Hlau
Kev ntsuas kev ua tau zoo qhia tau tias NM400 hnav resistant steel phaj ua tau zoo sib npaug lossis zoo dua qhov sib npaug thoob ntiaj teb:
| Pab pawg xeem | Qib | Hnav Ratio |
|---|---|---|
| Pab pawg A | NM 360 | 1.16 |
| Sweden Standard | Kev siv | 1.00 |
| Pab pawg B | NM 400 | 1.21 |
| Nyiv EH400 | Kev siv | 1.00 |
NM400 qhia tau tias txo qis hnav thiab ua kom zoo dua nyob rau hauv tib lub sijhawm.

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 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.
