Khoom Description
HP235 yog cov khoom siv zoo tshaj plaws rau qis- lub tog raj kheej siab siab vim tias nws ua rau muaj qhov sib npaug zoo ntawm cov kev xav tau kev nyab xeeb zoo rau cov hlab ntsha siab thiab kev lag luam xav tau ntawm siab - ntim khoom. Raws li qib tshwj xeeb steel nyob rau hauv Suav GB 6653 tus qauv, nws tau tsim tshwj xeeb los ua kom tau raws li qhov tshwj xeeb xav tau ntawm welded gas cylinders
HP235 welded lub tog raj kheej stee
Raws li lub ntiaj teb ua lag luam steel saw hlau pab pawg nrog 18+ xyoo dhau los, GNEE (Tianjin) Supply Chain Group Co., Ltd. tau mob siab rau muab siab -zoo kub- dov steel phaj rau welded gas cylinders txij thaum 2008. Nrog ntau tshaj 600 tuam txhab uas muag nyob rau hauv 100+ lub teb chaws, peb specializes du welded 2 welded steel 5 HP. Ua raws li GB / T 6653 tus qauv.
Cov laj thawj tseem ceeb rau xaiv HP235 welded lub tog raj kheej steel
Optimized rau Formability thiab Manufacture
Zoo heev Ductility: HP235 muaj qhov zoo tshaj plaws ductility piv rau nws qhov siab dua - zog counterparts. Nwselongation tom qab tawgtuaj yeem siab npaum li29%(rau cov khoom siv 3 hli tuab lossis ntau dua), uas yog qhov zoo dua li 26% ntawm HP295 lossis 22% ntawm HP325 . Qhov siab ductility no tso cai rau cov hlau txuas mus rau hauv cov duab nyuaj yam tsis muaj kua muag.
Tsawg Yield Ratio: Cov hlau yield ratio (yield zog faib los ntawm tensile lub zog) yog nruj me ntsis tswj los uaTsawg dua lossis sib npaug li 0.80. Ib qho piv txwv qis qhia tau hais tias cov khoom siv muaj peev xwm ua kom deform plastically ua ntej nws mus txog qhov kawg ntawm qhov tawg. Qhov no yog ib qho tseem ceeb thaum lub sij hawm tsim cov txheej txheem, raws li nws muab ib tug dav kev nyab xeeb margin thiab tiv thaiv tsis ua hauj lwm tam sim ntawd thaum lub sij hawm stamping.
Superior Weldability
Tsawg Carbon sib npaug: Cov tshuaj lom neeg muaj pes tsawg leeg ntawm HP235 nta cov ntsiab lus carbon tsawg tshaj plaws ntawm0.16%. Cov pa roj carbon tsawg tsawg no txo qis qhov kev pheej hmoo ntawm qhov txias txias hauv tshav kub- thaj tsam cuam tshuam (HAZ) ntawm cov vuam, tso cai rau cov welds muaj zog, zoo ib yam yam tsis tas yuav tsum muaj cov txheej txheem ua ntej thiab raug nqi.
Tswj impurities: Nws kuj muaj qhov txwv tsawg kawg nkaus rau leej faj (tsawg dua lossis sib npaug li 0.012%) thiab phosphorus (tsawg dua lossis sib npaug li 0.025%), uas yog impurities uas tuaj yeem ua rau kub tawg thaum lub sijhawm vuam. Qhov purity no ua kom muaj kev ncaj ncees ntawm kev sib koom ua ke.
Guaranteed Safety thiab Toughness
Impact Toughness: HP235 yuav tsum tau nqus qhov tsawg kawg nkauscuam tshuam lub zog ntawm 27 Joulesnyob rau hauv tus qauv Charpy V- ntsuas ntsuas ntawm chav tsev kub . Qhov no tau lees tias cov hlau yuav tsis tawg hauv qhov nkig yog tias raug cuam tshuam tam sim ntawd.
Tsawg-Kev Ua Haujlwm Kub: Rau cov thooj voos kheej kheej siv nyob rau hauv cov huab cua txias, cov khoom siv tuaj yeem raug teev kom ua tau raws li qhov zoo tshaj plaws qis -kub toughness. Cov txheej txheem tsim khoom niaj hnub rau chav kawm ntawm cov hlau no tuaj yeem ua tiav-20℃cuam tshuam toughness qhov tseem ceeb tshaj 50 Joules, deb tshaj tus qauv yuav tsum tau, kom muaj kev ruaj ntseg txawm nyob rau hauv freezing tej yam kev mob.
Kev xaiv nyiaj txiag zoo
HP235 tsis yog tsuas yog technically haum tab sis kuj muaj txiaj ntsig zoo.
Tus nqi -Kev ua tau zoo: Nws siv cov qauv sib npaug nrog cov nqi qis ntawm cov nqi kim micro-alloying ntsiab xws li niobium (Nb) thiab vanadium (V) piv rau qib siab dua - zog . Qhov no ua rau cov khoom siv raw khoom pheej yig dua.
Txheej txheem Efficiency: Nws zoo heev formability thiab weldability txhais kom tsawg raug tsis lees paub thiab ntau lawm throughput, ntxiv txo tus nqi tag nrho ntawm lub tog raj kheej ntau lawm.
Kev Xa Khoom
Kev Xa Khoom
- Kub-cov khoom dov: Xa hauv qhov kub- dov, tswj- dov, lossis cua sov- kho mob.
- Txias-cov khoom dov: Xa hauv qhov mob annealed.
- Pickled condition: Raws li kev pom zoo ntawm tus neeg muag khoom thiab tus neeg yuav khoom, kev xa khoom tuaj yeem ua rau kub - dov thiab pickled mob.
Quality Assurance thiab Txais
GNEE yuav tsum muab Daim Ntawv Pov Thawj Zoo ua raws li GB / T 6653-2017 tus qauv, uas muaj yam tsawg kawg nkaus cov ntaub ntawv hauv qab no:

Dab tsi yog qhov txias khoov zog ntawm HP235?
HP235 yuav tsum muaj peev xwm tiv taus 180℃txias dabtsi yog khoov kuaj. Lub bending mandrel txoj kab uas hla yuav tsum yog d=1.5a (qhov twg 'a' yog qhov tuab ntawm cov qauv kuaj), thiab tsis muaj cov kab nrib pleb yuav tsum tshwm rau sab nrauv ntawm cov qauv tom qab khoov. Qhov yuav tsum tau ua kom ntseeg tau tias cov khoom tsis tawg thaum lub sij hawm stamping thiab tsim cov roj lub tog raj kheej taub hau.
Dab tsi yog qhov vuam zog ntawm HP235? Puas yuav tsum tau preheating?
HP235 muaj cov khoom siv vuam zoo heev. Nws cov qauv tsim qis carbon sib npaug ua rau tsis muaj kev cuam tshuam rau qhov txias txias, thaum nws cov ntsiab lus tsis tshua muaj leej faj thiab phosphorus txo cov nyiam kub tawg. Nyob rau hauv ib txwm kub ambient kub thiab nrog nyias daim hlau, cov txheej txheem welding feem ntau -xws li roj-shielded vuam thiab submerged arc vuam- tuaj yeem ua yam tsis muaj preheating. Rau cov phaj tuab lossis qis - qhov kub thiab txias, cov txheej txheem vuam yuav tsum tau ua raws li qhov tsim nyog Vuam Txheej Txheem Specification (WPS).
Yuav ua li cas yog grain loj yuav tsum tau rau HP235?
Cov nplej loj ntawm HP235 yuav tsum tsis muaj coarser tshaj Qib 6, thiab qhov sib txawv ntawm cov nplej loj yuav tsum txwv tsis pub dhau peb qib sib law liag. Ib qho zoo -grained microstructure ua lub hauv paus rau kev ua tiav qhov zoo sib npaug ntawm lub zog thiab tawv, nrog rau cov khoom ruaj khov.
Puas yog HP235 haum rau kev kos duab sib sib zog nqus?
Yog, nws yog. Qhov yuav tsum tau elongation rau HP235 (qhov tsawg kawg nkaus ntawm Ntau dua lossis sib npaug li 29%) yog qhov siab tshaj qhov siab dua - qib zog xws li HP295 thiab HP325. Tsis tas li ntawd, nws muaj cov txiaj ntsig qis dua - rau - tensile lub zog piv thiab kev ua haujlwm nruab nrab - muaj peev xwm hardening, ua rau nws tsim nyog rau kev sib sib zog nqus - cov khoom sib sib zog nqus, xws li roj lub tog raj kheej taub hau.
