S355JR Channel Steel yog dab tsi?
S355JR Channel Steel yog cov qauv steel profile ua raws li EN 10025-2 nrog lub zog tawm los tsawg kawg ntawm 355 MPa. Qhov kev xaiv "JR" qhia tias nws raug kuaj ntawm 20 degree, ua rau nws tsim nyog rau kev siv cov qauv siv nyob rau hauv nruab nrab-kub ib puag ncig. Channel steel yog dav siv nyob rau hauv lub tsev lub moj khaum, industrial sheds, txuas hniav, thiab hnyav machinery Cheebtsam.
Dab tsi yog cov yam ntxwv ntawm S355JR Channel Steel?
S355JR Channel Steel muab qhov tsawg kawg nkaus tawm lub zog ntawm 355 MPa thiab lub zog tensile xws li 470 txog 630 MPa, nyob ntawm seb seem thiab thickness. Nws muaj qhov zoo ductility, tso cai rau nws nqus cov kev ntxhov siab yam tsis muaj qhov tsis ua haujlwm tam sim ntawd, thiab nthuav tawm kev txhim kho toughness haum rau welded thiab fabricated lug.
S355JR Channel Steel ua li cas hauv qab vuam?
Vim nws qhov sib npaug qis, S355JR Channel Steel yog yooj yim weldable siv cov txheej txheem vuam xws li SMAW, GMAW, lossis FCAW. Txawm li cas los xij, rau cov ntu tuab lossis cov pob qij txha uas muaj zog heev, tswj cov khoom siv hluav taws xob thiab ua raws li cov txheej txheem vuam kom zoo yog pom zoo kom tiv thaiv kom tsis txhob muaj kev ntxhov siab los yog softening nyob rau hauv tshav kub- cuam tshuam cheeb tsam (HAZ).
Vim li cas qhov cuam tshuam toughness tseem ceeb rau S355JR Channel Steel?
Impact toughness tiv thaiv brittle puas nyob rau hauv dynamic los yog cia li loads. S355JR tau raug sim ntawm 20℃kom ntseeg tau tias nws tuaj yeem tiv taus kev ua haujlwm zoo li qub. Rau cov haujlwm hauv cov huab cua txias, lwm qib xws li S355J0 lossis S355J2 tuaj yeem raug xaiv rau qis dua - qhov yuav tsum tau muaj qhov kub thiab txias.
S355JR Channel Steel piv nrog lwm cov qauv steel li cas?
Piv nrog S275JR, S355JR muaj lub zog muaj zog ntau dua, tso cai rau cov ntu sib dua thiab txo cov khoom siv thaum tswj kev ua haujlwm zoo. Piv nrog rau siab -lub zog quenched-thiab- tempered steels xws li S690, S355JR yog yooj yim rau fabricate thiab weld, txawm hais tias nws muaj qis tshaj lub zog, ua rau nws nqi ntau dua - siv tau rau kev siv dav siv.
Dab tsi yog cov ntawv thov ntawm S355JR Channel Steel?
S355JR Channel Steel feem ntau yog siv rau hauv lub tsev thav duab, txuas hniav, cov cuab yeej siv, tshuab hauv paus, thiab kev tsim kho vaj tse. Nws kev sib xyaw ua ke ntawm lub zog, weldability, thiab toughness ua kom muaj kev nyab xeeb thiab ruaj khov nyob rau hauv ntau hom kev siv thiab engineering.
