Kev piav qhia ntawm S355 N / NL Steel Phaj
S355 N steel phaj thiab S355 NL steel phaj yog weldable zoo grain qauv steel daim hlau, raws li EN 10025-3 tus qauv.
Tshuaj muaj pes tsawg leeg
1.Carbon tuaj yeem txhim kho qhov hardness thiab hnav tsis kam ntawm cov hlau, tab sis cov ntsiab lus ntau dhau yuav ua rau kom muaj zog brittleness thiab txo weldability. Yog li ntawd, cov ntsiab lus carbon nyob rau hauv steel phaj yog feem ntau tswj nyob rau hauv ib tug tsawg theem.
2.Cov khoom siv silicon feem ntau yog siv los ua deoxidizer hauv cov hlau, uas ua lub luag haujlwm ntawm kev tshem cov pa oxygen hauv cov hlau molten thiab txhim kho cov purity thiab zoo ntawm cov hlau.
3. Ntawm ib sab, manganese tuaj yeem txhim kho lub zog, hardness thiab toughness ntawm steel daim hlau. Ntawm qhov tod tes, nws tseem tuaj yeem txhim kho lub hardenability ntawm cov hlau, kom cov hlau phaj tuaj yeem tau txais cov qauv zoo dua thiab kev ua tau zoo tom qab quenching.
4.Cov ntsiab lus ntawm phosphorus thiab sulfur ntsiab yuav tsum tau tswj nruj me ntsis, txwv tsis pub nws yuav cuam tshuam rau steel lub plasticity thiab toughness.
Qhov sib ntxiv ntawm lwm cov hlau alloying tuaj yeem txhim kho corrosion kuj, siab kub lub zog thiab oxidation tsis kam ntawm steel phaj.
Qhov sib txawv ntawm S355N steel thiab S355 NL steel
Qhov sib txawv tseem ceeb ntawm S355N steel phaj thiab S355NL steel phaj yog raws li hauv qab no.
Qhov kub tsis kam ntawm S355NL steel phaj yog qhov zoo dua, thiab nws tuaj yeem tiv taus qhov kub ntawm qhov chaw ua haujlwm ntawm -50 degree, thiab qhov kub qis tshaj plaws uas S355N steel phaj tuaj yeem tiv taus yog -20 degree. Qhov no yog vim hais tias cov ntsiab lus boron thiab tooj liab hauv S355NL steel phaj tuaj yeem txhim kho qhov kub tsis tshua muaj zog thiab txias brittleness tsis kam ntawm steel phaj.
Cov ntsiab lus tooj liab siab ntawm S355NL ua rau muaj kev pheej hmoo ntawm molten hlau oxidation thiab tawg thaum lub vuam txheej txheem. Qhov no tsis yog qhov xwm txheej hauv S355N steel phaj.
S355N steel phaj yog tsim rau kev tsim khoom siv dav dav, kev tsim kho choj, kev tsim vaj tsev mining thiab lwm yam kev lag luam, feem ntau siv hauv kev tsim tsheb thiab cov khoom siv tshuab; S355NL steel phaj yog tsim rau kev tsim khoom siv hauv cov chaw txias, Marine cov qauv, roj av, tshuaj thiab lwm yam kev lag luam, feem ntau siv rau hauv ntug dej hiav txwv drilling platforms, roj tso tsheb hlau luam, cua zog yees thiab lwm yam khoom siv uas yuav tsum tau tiv taus qhov kub thiab txias ib puag ncig.
Xaus
Hauv luv luv, kev xaiv ntawm S355N steel phaj thiab S355NL steel phaj yuav tsum tau txiav txim siab raws li kev siv tshwj xeeb. Raws li tus kws tshaj lij hauv kev lag luam steel qauv, SYNERGIA tuaj yeem tsis tsuas yog muab cov ntawv zoo S355N / NL steel daim hlau tab sis kuj muab kev cob qhia kev cob qhia. Kawm paub cov ncauj lus kom ntxaws ntxiv ntawm S355 steel phaj los ntawm kev tiv tauj peb tam sim no!
