A537CL1 siab lub nkoj steel phajCov lus qhia ntxaws
A537CL1 steel phaj yog ib hom kev ua tau zoo alloy steel phaj, uas yog tsuas yog siv nyob rau hauv kev tsim cov khoom siv lub nkoj siab hauv roj av, tshuaj lom neeg kev lag luam, chaw nres tsheb fais fab, boiler thiab lwm yam lag luam.
A537CL1 steel phajmuaj siab mechanical zog
Yield zog: Qhov tsawg kawg nkaus tus nqi yog 345 MPa (qhov tsis kam rau cov yas deformation ntawm cov khoom pib thaum lub sij hawm ncab).
Lub zog tensile: Qhov tsawg kawg nkaus tus nqi yog 485-620 MPa (qhov siab tshaj plaws bearing muaj peev xwm ntawm cov khoom thaum lub sij hawm tensile txheej txheem).
Elongation: Qhov tsawg kawg nkaus tus nqi yog 22% (qhov degree ntawm tensile deformation ntawm cov khoom ua ntej tawg).
Impact toughness: Ntawm -46 degree C, qhov tsawg kawg nkaus qhov nruab nrab absorbed zog yog 27 J (raws li tus qauv xeem tej yam kev mob).
Qhov chaw zoo ntawm A537CL1 steel phaj yuav tsum ua tau raws li cov qauv tsim nyog, feem ntau suav nrog cov hauv qab no
Nto tiav: qhov saum npoo ntawm cov hlau phaj yuav tsum du thiab tiaj tus, tsis muaj qhov tsis sib xws, khawb, pitting thiab lwm yam tsis xws luag.
Cov kab nrib pleb: qhov saum npoo ntawm cov hlau phaj yuav tsum tsis txhob muaj cov kab nrib pleb, nti, folding thiab lwm yam tsis xws luag, cov kev tsis xws luag no yuav cuam tshuam rau cov khoom siv kho tshuab thiab corrosion kuj ntawm steel phaj.
Deg corrosion: saum npoo ntawm cov hlau phaj yuav tsum tsis muaj xeb, oxide thiab lwm yam kuab paug, uas yuav cuam tshuam rau qhov zoo ntawm qhov chaw thiab kev ua haujlwm tom qab ntawm cov hlau phaj.
Kev huv ntawm qhov chaw: Qhov saum npoo ntawm cov hlau phaj yuav tsum huv si, tsis muaj roj, dej thiab lwm yam impurities, los xyuas kom meej qhov ruaj khov thiab kev ntseeg siab ntawm cov phaj hlau hauv kev ua haujlwm tom qab thiab siv cov txheej txheem.
