Q355 yog lub siab-zog qes qis-alloy (hsla) cov hlau qauv uas muaj phosphorus, leej faj, xws li microolys, thiab lwm yam ntawm cov vanadium, thiab lwm tus. Nws zoo ib yam li Q345 nyob rau hauv cov nqe lus ntawm cov tshuaj muaj kuab lom tab sis muaj zog loj dua, thiab muaj hwj chim.
Q355 steel muaj lub zog tensile ntawm 490-630 mpa mpa cia ntawm 20%, ua rau nws siv ntau yam qauv xws li txuas hniav, vaj tse, thiab tshuab.
Qee cov yam ntxwv tseem ceeb thiab cov khoom ntawm Q355 hlau muaj xws li:
Superior zog: Q355 lub zog muaj zog dua thiab tawm lub zog ntau dua Q345 lub zog rau kev siv hauv cov kev siv ntxhov siab qib siab.
Zoo weldability: Q355 steel muaj zoo weldability, uas ua rau nws yooj yim rau fabricate thiab tsim.
Kev nyuaj heev: Q355 cov khoom ua pov thawj zoo heev tau yooj yim heev, tso cai rau nws tiv thaiv cuam tshuam kev cuam tshuam thiab tiv thaiv tsis zoo.
Corrosion Kuj: Q355 steel muaj zoo corrosion tsis kam, ua rau nws tsim nyog rau kev siv nyob rau hauv ib puag ncig sab nraum zoov thiab marrine sab nraum zoov.
Nqis: Txawm tias muaj cov khoom lag luam zoo tshaj, Q355 steel nyob rau cov kev xaiv hlau pheej yig rau cov qauv hlau.
Nyob rau hauv cov ntsiab lus, Q355 yog ib tug high-strength low-alloy structural steel nrog superior zog, zoo weldability, zoo heev toughness, thiab corrosion kuj. Nws cov khoom sib xyaw ua ke ua rau nws zoo tagnrho rau kev siv ntau yam kev siv cov qauv uas muaj zog thiab kav ntev yog qhov tseem ceeb.
Q355 Cov ntaub ntawv sib npaug
Q355 tuaj yeem hloov nrog cov ntaub ntawv sib npaug, suav nrog A572 Qib 50 Tebchaws ATA ASTM, Q355 Tuam Tshoj GB / T, thiab Spfc 590 Jis.
Cov yam ntxwv ntawm Q355
Q355 steel yog cov qauv hlau nrog lub zog tawm ntawm 345 MPa thiab tensile zog ntawm 450 MPa. Nws muaj kev ua tau zoo heev thiab lub zog compressive, uas tuaj yeem siv los tsim cov pa roj siab siab uas muaj tsawg dua 500 litres. Q355 kuj muaj cov txheej txheem tiv thaiv xeb.
Ntxiv rau qhov ua tau zoo, Q355 muaj cov ntsiab lus tshwj xeeb uas tiv thaiv atmospheric corrosion. Vim nws yog cov hlau me me, nws muaj cov ntsiab lus qis carbon. Yog tias cov pa roj carbon ntau ntxiv rau cov hlau, nws yuav raug muab faib ua cov hlau cam khwb cia.
