Qhov sib txawv ntawm weldability thiab machinability
- NM400: NM400 paub txog nws qhov zoo weldability thiab machinability, thiab tuaj yeem txiav, khoov, thiab welded siv cov cuab yeej txheem. Txawm li cas los xij, rau cov phaj tuab, kev ua kom sov yog pom zoo (piv txwv li, preheating kub 75-150 degree, nyob ntawm qhov tuab). Cov cuab yeej carbide tau pom zoo rau kev ua haujlwm, thiab txiav ceev yuav tsum tau tswj.
- AR400: Piv rau cov hlau hnyav xws li AR500, AR400 yooj yim dua rau vuam thiab tshuab. AR400F muaj ntau dua formability, uas pab txo cov kev tsim khoom thiab txo cov nqi. Txawm li cas los xij, yuav tsum tau saib xyuas thaum lub sij hawm vuam kom tsis txhob muaj teeb meem hauv tshav kub - cuam tshuam cheeb tsam (HAZ).
Txawv daim ntawv thov tsom
Ob hom hlau yog siv nyob rau hauv siab -ib puag ncig, tab sis lawv qhov zoo sib txawv:
- NM400: Siv dav hauv mining machinery, siv cov khoom siv, thiab chaw nres nkoj machinery, xws li chutes, hoppers, thiab crusher liners. Nws tus nqi siab-kev ua tau zoo ua rau nws zoo tagnrho rau kev siv nyiaj-cov haujlwm tseem ceeb hauv Asia.
- AR400: Siv dav hauv North American cov ntawv thov kev lag luam, xws li cov tsheb thauj khoom pov tseg, tsheb loj loj, thiab hnav ib daim hlab. Nws cov kev cuam tshuam zoo heev ua rau nws haum rau cov cuab yeej hnyav uas raug rov cuam tshuam dua.

FAQ:
1.NM400 steel yog dab tsi?
NM400: Suav- qauv hnav- cov hlau resistant (NM stands rau "Nai Mo," txhais tau tias hnav-resistant hauv Suav), NM400 feem ntau muaj Brinell hardness (HBW) ntawm 360–440. Nws paub txog nws qhov sib npaug ntawm hardness, toughness, thiab nqi -effectiveness, ua rau nws nrov nyob rau hauv Asia thiab tshaj.
2.Yog AR400 muaj zog dua AR500?
Ntawm no yog li cas nws stacks: AR400 AR500: Vim nws cov ntsiab lus manganese ntau dua, AR500 yog li 1.25 npaug zog (500 HBW) thiab muaj kev cuam tshuam zoo dua li AR400. Txawm li cas los xij, nws kuj yog nkig ntau dua, ua rau nws tsawg formable. Nws lub zog thiab corrosion kuj ua rau nws zoo tshaj plaws rau siab - cuam tshuam ib puag ncig.
3.Dab tsi yog qhov txawv ntawm AR500 thiab NM500?
AR500: Cov pa roj carbon ntau (C: ~ 0.38-0.45%), chromium (Cr: ~ 1.5%), thiab boron (B: 0.0005-0.006%) rau kev txhim kho hardness thiab corrosion kuj. NM500: Tsawg carbon (C: Tsawg dua lossis sib npaug rau 0.38%), ntxiv nickel (Ni: Tsawg dua lossis sib npaug li 1.0%) thiab molybdenum (Mo: Tsawg dua lossis sib npaug li 0.65%) rau kev sib npaug weldability thiab toughness.
4.Yog AR400 muaj zog dua li cov hlau me me?
Nws cov ntsiab lus carbon siab, nrog rau nws cov ntsiab lus alloy ua rau AR400 tsis yog tsuas yog muaj zog dua li cov hlau me me, tab sis kuj tswj cov tshuab nruab nrab thiab tsim tau. Cov yam ntxwv tshwj xeeb ua rau qhov no yog cov khoom lag luam zoo tshaj plaws rau kev tsim kho, kev tuav cov khoom, mining, thiab lwm yam kev puas tsuaj, zoo ib yam li AR500 steel phaj.
5.Koj puas xav tau preheat AR400 steel?
Thaum vuam cov khoom siv tawv tawv tawv, tshem tawm MOISTURE. QHOV TSEEM CEEB thiab zam qhov kub thiab txias: Preheat qhov chaw weld. (Hauv qhov xwm txheej uas ua ntej- cua sov tsis tuaj yeem ua tau, siv 309 Stainless Rod yuav raug txiav txim siab.)
