Iqhia:
Hauv kev tsim cov hlau, ob qib sawv tawm-S275JR thiab S355JR. Ob leeg koom nrog EN10025-2 tus qauv thiab tau siv dav hauv ntau yam lag luam. Txawm hais tias lawv cov npe zoo sib xws, cov qib no muaj cov khoom tshwj xeeb uas ua rau lawv sib nrug. Hauv blog no, peb'yuav delve rau hauv lawv lub ntsiab sib txawv thiab zoo sib xws, tshuaj xyuas lawv cov tshuaj muaj pes tsawg leeg, mechanical zog, thiab cov ntaub ntawv cov khoom.
Qhov sib txawv ntawm cov tshuaj muaj pes tsawg leeg:
Ua ntej, cia's hais txog qhov sib txawv ntawm cov tshuaj muaj pes tsawg leeg. S275JR yog carbon hlau, thaum S355JR yog cov hlau tsis tshua muaj hlau. Qhov sib txawv no nyob hauv lawv cov ntsiab lus tseem ceeb. Cov pa roj carbon steel muaj cov hlau thiab cov pa roj carbon ntau, nrog rau cov khoom me me ntawm lwm cov ntsiab lus. Ntawm qhov tod tes, cov hlau tsis tshua muaj hlau, xws li S355JR, muaj cov alloying ntxiv xws li manganese, silicon, thiab phosphorus, uas txhim kho lawv cov khoom.
Mechanical cwj pwm:
Hais txog cov khoom siv kho tshuab, S275JR thiab S355JR qhia qhov sib txawv tseem ceeb. Qhov tsawg kawg nkaus tawm lub zog ntawm S275JR yog 275MPa, thaum lub S355JR yog 355MPa. Qhov sib txawv ntawm lub zog no ua rau S355JR zoo tagnrho rau cov qauv siv uas xav tau lub zog ntau dua los tiv thaiv cov khoom hnyav. Txawm li cas los xij, nws yuav tsum raug sau tseg tias lub zog tensile ntawm S355JR tsawg dua li ntawm S275JR.
Khoom siv:
Los ntawm kev xav ntawm daim ntawv khoom, S275JR zoo ib yam li S355JR. Ob qib yog siv nyob rau hauv kev tsim cov khoom tiaj tus thiab ntev ntev xws li steel phaj thiab steel kav. Cov khoom no yog tsim los rau ntau yam kev siv hauv kev lag luam xws li kev tsim kho mus rau kev siv tshuab. Tsis tas li ntawd, cov khoom semi-tiav ua los ntawm kub dov tsis-alloy high-zoo hlau tuaj yeem ua tiav rau hauv ntau yam khoom tiav.
EN10025-2 tus qauv:
Txhawm rau muab cov ntsiab lus dav dav, peb tham txog EN10025-2 tus qauv uas siv rau S275JR thiab S355JR. Qhov European Standard no qhia txog cov txheej txheem kev xa khoom rau cov khoom tiaj tus thiab ntev, nrog rau cov phaj thiab cov raj. Nws kuj suav nrog cov khoom lag luam semi-tiav uas tau ua tiav ntxiv. Cov qauv no ua kom zoo ib yam ntawm cov qib sib txawv thiab cov khoom zoo ntawm cov hlau tsis muaj hlau.
Dab tsi S275JR thiab S355JR muaj sib xws:
Txawm hais tias lawv qhov sib txawv, S275JR thiab S355JR muaj qee yam sib xws. Ob qib ua raws li EN10025-2 cov qauv, ua kom pom tias lawv ua raws li kev tswj hwm nruj. Tsis tas li ntawd, lawv muaj ntau yam kev siv hauv ntau qhov kev lag luam vim lawv cov khoom zoo, nrog rau cov weldability zoo thiab kev ua haujlwm zoo. Tsis tas li ntawd, ob qib yog cov kev xaiv nrov rau cov qauv hlau thiab tuaj yeem muab lawv tus kheej zoo nyob ntawm cov kev xav tau tshwj xeeb.
Hauv cov ntsiab lus:
Los xaus, S275JR thiab S355JR tej zaum yuav muaj cov npe zoo sib xws, tab sis lawv yog cov qib sib txawv ntawm cov hlau nrog cov khoom tshwj xeeb.. S275JR yog carbon hlau, thaum S355JR yog cov hlau tsis tshua muaj hlau nrog cov khoom siv sib txawv thiab tshuaj lom neeg. Txawm li cas los xij, lawv txhua tus ua raws tib tus qauv EN10025-2, ua kom zoo thiab ua raws li cov txheej txheem xa khoom. Kev nkag siab txog qhov sib txawv thiab qhov sib xws yog qhov tseem ceeb rau kev xaiv cov qib zoo rau cov ntawv thov tshwj xeeb thiab cov kev xav tau. Xaiv cov qib raug yog ib qho tseem ceeb los xyuas kom meej qhov ua tau zoo ntawm koj qhov project. Ua haujlwm nrog kev tshaj lij cov neeg muab khoomntawm S275JR, S355JR cov ntaub ntawvxws li Shandong Jinbaicheng Hlau Khoom Co., Ltd. lav cov khoom zoo raws li koj cov kev xav tau tshwj xeeb.
