NV A500 steel phaj ntawm cov thicknesses sib txawv muaj qhov sib txawv hauv qab no hauv kev ua haujlwm:

Mechanical Properties

 

Yield zog: Qhov tsawg kawg nkaus yield zog ntawm NV A500 steel daim hlau ntawm txawv thicknesses yog 500MPa. Txawm li cas los xij, nyob rau hauv qhov tseeb ntau lawm, raws li lub thickness nce, lub zog tawm los yuav hloov me ntsis vim yog yam xws li cov txheej txheem dov. Tab sis feem ntau, nws yuav tsum ua kom tau raws li qhov yuav tsum tau ua kom tsawg dua 500MPa.

Tensile zog: Lub zog tensile feem ntau yog li ntawm 610MPa txog 770MPa. Qhov kev hloov ntawm thickness muaj me ntsis cuam tshuam rau ntau yam ntawm tensile lub zog. Txawm li cas los xij, thaum lub sij hawm dov txheej txheem ntawm cov hlau phaj tuab, yam xws li cov kev ntxhov siab sab hauv tuaj yeem ua rau lub zog tensile tiag tiag kom ze rau qhov qis dua.

Elongation: Qhov tsawg kawg nkaus elongation yog 16%. Feem ntau, thinner steel daim hlau yog yooj yim dua mus cuag los yog tshaj qhov elongation Performance index. Thicker steel daim hlau yuav muaj qhov elongation qis dua vim muaj teeb meem xws li cov qauv sab hauv, tab sis lawv kuj yuav tsum tau ua kom tau raws li qhov yuav tsum tau muaj tsawg kawg yog 16%.

 

Vuam Performance

 

Thaum welding thinner NV A500 steel daim hlau, kev hloov hluav taws xob yog ceev ceev, thiab qhov cua txias ntawm qhov sib koom ua ke kuj tseem ceev, uas yooj yim ua rau kev tsim cov qauv nyuaj thiab txo qhov toughness ntawm welded sib koom. Yog li ntawd, nyob rau hauv cov txheej txheem vuam, tsis xws li ib tug me me vuam tam sim no thiab ib tug ceev vuam ceev yuav tsum tau los tswj lub tshav kub input thiab txo qhov kev cuam tshuam ntawm kev ua tau zoo ntawm cov welded sib koom.

Thaum welding thicker steel daim hlau, vim hais tias lawv dissipate tshav kub kuj maj mam, muaj kev ntxhov siab ntau dua thaum lub vuam txheej txheem, thiab vuam deformation thiab vuam tawg thiab lwm yam tsis xws luag yuav tshwm sim. Txhawm rau ua kom cov vuam zoo, cov txheej txheem vuam nruj dua yuav tsum tau ua, xws li cov txheej txheem vuam tsim nyog, kev kho ua ntej deformation, tom qab - vuam kev kho cua sov, thiab lwm yam., txhawm rau txo vuam kev ntxhov siab thiab tiv thaiv qhov tshwm sim ntawm vuam tsis xws luag.

Corrosion Resistance

 

Feem ntau hais lus, lub thickness nws tus kheej tsis muaj kev cuam tshuam ncaj qha rau corrosion kuj ntawm NV A500 steel daim hlau. Txawm li cas los xij, thaum siv cov phaj tuab tuab, vim lawv cov ntoo ntoo loj dua - ntu, hauv tib qhov chaw corrosive, qhov nruab nrab corrosive yuav siv sij hawm ntev dua kom ncav cuag sab hauv ntawm cov hlau phaj, uas yuav ua rau muaj kev pheej hmoo ntawm corrosion.

Nyob rau hauv cov ntaub ntawv siv tau, rau thicker NV A500 steel daim hlau, yuav xav tau kev tiv thaiv corrosion zoo dua, xws li nce lub thickness ntawm cov tshuaj tiv thaiv corrosion thiab siv ntau dua corrosion-resistant cov ntaub ntawv, los txhim kho lawv cov corrosion kuj thiab ntev lawv cov kev pab cuam. lub neej.

Machineability

 

Thinner NV A500 steel daim hlau yog softer thiab yooj yim rau kev ua thiab tsim. Lawv tuaj yeem ua rau ntau yam - zoo li cov khoom los ntawm txias - dabtsi yog khoov, stamping, thiab lwm yam, thiab qhov tseeb qhov tseeb thiab qhov chaw zoo tom qab ua haujlwm zoo dua. Txawm li cas los xij, thaum lub sij hawm ua, kev saib xyuas kuj yuav tsum tau them nyiaj rau kev tiv thaiv khawb thiab deformations ntawm cov hlau phaj nto.

Thicker steel phaj yog qhov nyuaj thiab nyuaj rau kev ua haujlwm. Lub zog sab nraud loj dua yog xav tau thaum lub caij txias - ua haujlwm, thiab kev ua haujlwm - hardening tshwm sim yuav tshwm sim, uas ua rau txo qis ntawm cov hlau daim hlau. Yog li ntawd, rau cov phaj tuab tuab, kub - kev ua haujlwm xws li kub - dabtsi yog khoov thiab kub - stamping feem ntau yog siv. Txawm li cas los xij, thaum lub sijhawm ua haujlwm kub, qhov kub thiab txias thiab tuav lub sijhawm yuav tsum tau tswj kom nruj kom tsis txhob overheating ntawm steel phaj qauv thiab cuam tshuam rau nws cov kev ua tau zoo.
