NM400 hnav-resistant steel phaj yog cov khoom siv dab tsi NM400 Cov khoom dab tsi
NM400 hnav-resistant steel yog ib tug hardness ntawm 400HBW qib hnav-resistant steel xa mus rau, NM400 yog dav siv nyob rau hauv kev tsim kho machinery, mining, tshuaj thiab lwm yam lag luam, kom nkag siab txog cov khoom thiab kev ua tau zoo ntawm NM400, raws li nram no lub teb chaws Yelemees Dillingen steel ntau lawm ntawm 400 qib hnav-resistant steel ua piv txwv los piav qhia.
Hom Lub Npe: DILLIDUR 400
Kev xa khoom: tswj dej sov quenching
Delivery condition mechanical zog
DILLIDUR 400 yog ib qho hnav-resistant steel phaj nrog qhov nruab nrab hardness ntawm 400HBW xa los ntawm lub Hoobkas, thiab nws cov khoom siv tshuab tau txais los ntawm quenching. DILLIDUR 400 tau pom zoo rau cov ntawv thov hauv qhov chaw hnav khaub ncaws siab, thiab nws kuj muaj kev ua haujlwm zoo, tshwj xeeb tshaj yog rau vuam.
Transverse specimen tensile test at room temperature (20mm tuab steel phaj siv tus nqi)
Tensile zog: 1200 MPa (175 ksi)
Tawm taw tes: 800 MPa (116 ksi)
Elongation: 12% (Lo=5.65 √So)
kev ua tau zoo
Kev ua tiav thiab kev siv thev naus laus zis tau txais los ntawm tus neeg siv yog qhov tseem ceeb rau kev ntseeg siab ntawm cov khoom tsim los ntawm cov khoom siv no. Nws yuav tsum tau ua kom paub tseeb tias cov qauv tsim, kev tsim kho thiab kev ua haujlwm yog tsim nyog rau cov khoom siv thiab ua raws li cov txheej txheem ua haujlwm tshiab uas yuav tsum tau ua raws li cov txheej txheem thiab cov kev xav tau ntawm cov khoom siv. Tus neeg siv yuav tsum xaiv cov khoom los ntawm nws tus kheej, thiab ua tiav cov txiaj ntsig ntawm cov yam ntxwv ntawm lub zog siab thiab siab tawv ntawm cov khoom, ua raws li cov txheej txheem kev pom zoo raws li EN 1011-2 (vuam) thiab CEN / TR 10347 (moulding) , thiab ua raws li lub teb chaws txoj cai ntawm kev ruaj ntseg ntau lawm.
Txias txoj kev
Txawm hais tias DILLIDUR 400 yog tus cwj pwm los ntawm qhov nyuaj thiab lub zog, nws tseem tuaj yeem ua txias-tsim los ntawm kev khoov. Nws yuav tsum tau muab sau tseg tias nrog rau kev nce ntawm lub zog tawm los, lub molding quab yuam yuav tsum tau rau tib thickness steel phaj yuav tsum tau nce, thiab cov resilience kuj yuav nce. Txhawm rau kom tsis txhob muaj kev pheej hmoo ntawm ntug kev tawg, nplaim taws txiav ntug lossis shear ntug ntawm qhov chaw txias txias yuav tsum tau polished. Tsis tas li ntawd, nws raug pom zoo tias sab ntug ntawm qhov khoov yuav maj mam thiab smoothly polished thaum raug tensile kev nyuaj siab thaum khoov.
Thaum lub sijhawm ua haujlwm, kev ntsuas kev nyab xeeb tsim nyog yuav tsum tau ua kom ntseeg tau tias cov neeg ua haujlwm tsis raug cuam tshuam rau qhov kev pheej hmoo ntawm kev tawg lub workpiece thaum molding.
thermoforming
DILLIDUR 400 ua tiav hardness los ntawm kev ua kom txias los ntawm austenitizing kub. Tom qab thermoforming, nws tsuas yog ua tau kom rov zoo li qub hardness los ntawm kev rov quenching. Nws tuaj yeem cia siab tias qhov hardness tau tom qab rov quenching yuav txawv ntawm qhov hardness ntsuas ntawm lub Hoobkas ntawm steel phaj, vim hais tias cov quenching khoom siv nyob rau hauv zus tau tej cov steel daim hlau thiab cov quenching khoom uas muaj los ntawm cov txheej txheem cog muaj qhov sib txawv nyob rau hauv lub quenching khoom. muaj peev xwm.
Cov khoom siv no tuaj yeem ua kom sov li ntawm 250 degree (482 degree F) yam tsis muaj qhov hnyav hnyav.
Nplaim txiav thiab vuam
Nplaim txiav yuav tsum ua raws li nram no yam tsawg kawg nkaus preheating kub: phaj thickness 30 ~ 50mm, 75 degree (170 degree F); Phaj thickness 50 ~ 100mm, 100 degree (212 degree F); Phaj thickness ntau tshaj 100mm, 150 degree (302 degree F).
tshuab
Lub DILLIDUR 400V tuaj yeem siv cov khoom siv high-speed steel, tshwj xeeb tshaj yog cobalt alloy high-speed cov khoom. Yog tias siv tus nqi nkag thiab nkag mus tau zoo, qhov me ntsis tuaj yeem ua tiav kev pabcuam lub neej.
General technical delivery yuav tsum
Tshwj tsis yog tias pom zoo, cov txheej txheem xa khoom dav dav yuav tsum tau siv EN 10021.
