WearTuf 450 Abrasion Resistant Steel Phaj

Yam ntxwv
WearTuf 450 yog tag nrho martensitic Q&T abrasion resistant steel muaj ib tug hardness ntawm nruab nrab 450 Brinell. WearTuf 450 muab cov khoom siv tiv thaiv zoo nrog cov weldability zoo thiab muaj peev xwm ua kom txias. Vim muaj kev cuam tshuam loj heev, WearTuf 450 muaj kev sib tsoo zoo heev.

Qhov ntev
WearTuf 450 yog nkag rau hauv lub thickness ntawm 3.0 - 60.0 hli thiab nyob rau hauv lub phaj dav ntawm 900 - 3 100 hli. Muab phaj ntev los ntawm 4 000 rau 18 000 mm.

Impact toughness
45J/-40 ° C (-40 ° F)
Qhov cuam tshuam toughness yog muab raws li lub zog nqus ntawm qhov kub thiab txias, yog qhov nruab nrab ntawm peb qhov loj tag nrho Charpy-V kuaj cov qauv nyob rau hauv longitudinal kev taw qhia rau dov, raws li EN ISO 148-1.

Hardness guarantee
Nto hardness: 425-475 Brinell
Tau lees paub qhov hardness ntau yam, ntsuas rau ntawm qhov chaw milled ntawm qhov tob ntawm 0.5 - 2.0 hli hauv qab phaj saum npoo, raws li ISO EN 6506-1.
Min nruab nrab hardness:
Phaj thickness ≤ 20mm: min 425 Brinell
Phaj thickness ＞ 20mm: 95% ntawm min lav hardness.

Daim ntawv thov
WearTuf 450 haum rau ntau yam kev siv sib txawv hauv lub ntiaj teb txav, mining thiab thauj khoom. WearTuf 450 yog tsim tshwj xeeb rau cov ntawv thov tsom rau lub teeb yuag tsim lub tswv yim, xws li nyob rau hauv thiab tawm txoj kev dumper thiab tipper lub cev, qhib sab saum toj ntim, qhob tov khoom thiab cov tsheb thauj khoom khib nyiab.

Kev kuaj ultrasonic
Txhua daim hlau xa tuaj raws li Chav Kawm E1, S1 qhov yuav tsum tau ua, raws li EN 10 160.

Kev xa khoom
WearTuf 450 raug xa mus rau hauv qhov xwm txheej quenched (Q), thiab thaum pom tias tsim nyog nyob rau hauv qhov xwm txheej ntawm quenched thiab tempered (QT).
Cov phaj yog xa nrog sheared los yog thermally txiav npoo.

Ua siab ntev
Lub thickness kam rau ua ntawm WearTuf 450 ua tau raws li thiab tshaj qhov thickness kam rau ua ntawm EN 10 029
Chav A. Kev kam rau siab ntawm cov duab, qhov ntev, thiab qhov dav ua tau raws li qhov yuav tsum tau ua ntawm EN 10029. Flatness kam rau ua raws li EN 10 029 Class S lossis ze dua.

Deg mob thiab cov khoom
Kev xa khoom nto tiav raws li thiab tshaj EN 10163-2 Class A, Subclass 3.
Cov daim hlau yuav raug xa tawm raws li cov xim pleev xim, siv cov zinc silicate corrosion tiv thaiv khw primer tsawg. Cov phaj kuj tuaj yeem xa tuaj raws li tsis muaj xim.

Kev kho cua sov
Txij li thaum cov khoom nyob rau hauv raws li tus neeg mob tus me nyuam tsis tuaj yeem khaws cia tom qab raug ntawm qhov kev pab cuam kub siab tshaj 250 ° C, WearTuf 450 tsis yog npaj rau kev kho cua sov ntxiv.

Tshuaj muaj pes tsawg leeg
Ladle tsom xam: Cov hlau yog grain refined thiab tag nrho tua, wt%
