A517Gr steel phaj nthuav dav qhia
Tag nrho A517Gr series steel daim hlau muaj lub zog siab, zoo toughness thiab tsis tshua muaj tawg rhiab heev.
Lawv feem ntau siv los tsim cov khoom siv lossis cov khoom siv uas xav tau cov khoom siv siab, xws li cov hlab ntsha siab, boilers, offshore platforms, nkoj, thiab lwm yam.
Tshuaj muaj pes tsawg leeg ntawm A517Gr steel phaj:
Cov pa roj carbon (C): 010-0.20%. Cov pa roj carbon monoxide yog lub ntsiab alloying hauv cov hlau thiab muaj qhov cuam tshuam loj rau lub zog thiab hardness ntawm steel. Cov ntsiab lus ntawm cov pa roj carbon zoo tuaj yeem txhim kho lub zog thiab hardness ntawm cov hlau, tab sis siab dhau yuav ua rau kom muaj zog ntawm cov hlau.
Manganese (Mn): 0 60-1 00%. Manganese nyob rau hauv steel raws li deoxidizer thiab desulfurizer, tuaj yeem txhim kho lub zog thiab hardness ntawm hlau, txhim kho kev ua haujlwm txias ntawm cov hlau, thiab pab txhim kho cov hardenability ntawm hlau.
Phosphorus (P): Tsawg dua lossis sib npaug rau 0.035%. Phosphorus feem ntau suav hais tias yog ib qho teeb meem hauv cov hlau vim tias nws txo cov ductility thiab toughness ntawm cov hlau thiab ua rau kom txias brittleness ntawm hlau. Yog li ntawd, nws yog ib qho tsim nyog yuav tsum nruj me ntsis tswj cov ntsiab lus ntawm phosphorus hauv cov txheej txheem ntawm cov hlau.
Sulfur (S): Tsawg dua lossis sib npaug rau 0.035%. Sulfur kuj yog ib qho teeb meem, uas yuav ua rau kub brittleness ntawm hlau thaum kub ua, txo cov neeg kho tshuab zog thiab weldability ntawm hlau.
Silicon (Si): 0 15-0.35%. Silicon feem ntau ua lub luag haujlwm deoxidation hauv steel, uas tuaj yeem txhim kho lub zog thiab hardness ntawm steel, tab sis kuj txo cov yas thiab toughness ntawm hlau.
Mechanical zog ntawm S275J2 steel phaj
A517GrA: Raws li cov chav kawm hauv A517 series, A517GrA steel phaj kuj muaj cov yam ntxwv ntawm lub zog siab, zoo kub kub toughness thiab tsawg tawg rhiab heev. Cov kev ua haujlwm tshwj xeeb thiab thaj chaw siv yuav txawv nyob ntawm qhov tsim thiab siv tiag tiag.
A517GrB: Qib no ntawm steel phaj belongs rau American standard siab lub nkoj quenched + tempered high-strength alloy steel phaj, nrog siab zog thiab toughness, haum rau tej lub sij hawm nrog cov khoom siab kev ua tau zoo.
A517GrH: A517GrH steel phaj yog lub zog siab qis-alloy structural steel raws li American ASTM tus qauv, tseem hu ua "high-strength Cr-Mo steel". Nws muaj cov cuab yeej zoo txhua yam, suav nrog lub zog siab, hnav tsis kam, tsis tshua muaj kub toughness, thiab lwm yam, thiab yog siv dav hauv kev tsim cov khoom tseem ceeb xws li cov hlab ntsha thiab cov boilers.
A517GrQ: Raws li lwm qib ntawm A517 series, A517GrQ steel phaj kuj muaj lub zog siab thiab kev ua tau zoo tag nrho, haum rau ntau hom kev lag luam high-end.
A517GrS: Txawm hais tias tsis muaj cov ntaub ntawv tshwj xeeb txog A517GrS steel phaj, nws tuaj yeem suav tau tias nws kuj yog lub zog siab tempered steel phaj ntawm A517 series, uas muaj cov yam ntxwv zoo ntawm cov phaj hlau no.
A517GrP: Qib no ntawm steel phaj kuj yog ib tug tswv cuab ntawm A517 series, thiab qhov tshwj xeeb kev ua tau zoo thiab daim ntawv thov cov cheeb tsam yuav txawv nyob ntawm seb qhov kev xav tau ntau lawm.
A517GrF: Raws li tau hais los saum no, A517GrF steel phaj muaj cov yam ntxwv ntawm lub zog siab, zoo toughness thiab tsis tshua muaj tawg rhiab heev, thiab yog qib tseem ceeb hauv A517 series.
A517GrE: A517GrE steel phaj yog qhov ua tau zoo alloy steel phaj nrog lub zog tensile siab thiab lub zog tawm los, nrog rau zoo plasticity thiab toughness. Nws yog dav siv hauv kev lag luam petrochemical, dej hiav txwv engineering, choj kev tsim kho, cov tsev siab siab thiab lwm yam haujlwm.
