Qib Q355 steel
Q355steel khoom Taw qhia
Q355 steel yog qib high-strength steel qauv uas feem ntau siv nyob rau hauv ntau yam lag luam thiab kev siv. Txawm li cas los xij, nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias tsis muaj "qib" ntawm Q355 steel vim nws tsis raug cais los ntawm cov qauv qib ib txwm muaj xws li Q235 lossis Q345. Hloov chaw, Q355 feem ntau yog categorized raws li nws cov tshuaj muaj pes tsawg leeg thiab cov khoom siv tshuab.
Muaj ntau qhov sib txawv lossis hom Q355 steel, xws li Q355B, Q355C, Q355D, thiab Q355E, txhua tus muaj nws tus kheej tshwj xeeb muaj pes tsawg leeg thiab cov khoom. Cov kev hloov pauv no txawv ntawm yam xws li cov ntsiab lus carbon, ntxiv cov ntsiab lus alloying, thiab cov txheej txheem kho cua sov tshwj xeeb.
Q355B
Hom Q355 steel no yog tus cwj pwm los ntawm cov ntsiab lus carbon ntau dua, feem ntau yog li ntawm 0.20% mus rau 0.25%. Nws muaj qhov zoo weldability thiab formability, ua rau nws haum rau cov qauv siv uas yuav tsum tau muaj zog thiab toughness. Q355B feem ntau yog siv rau hauv kev tsim vaj tsev, txuas hniav, thiab tshuab.
Q355C
Q355C steel muaj cov pa roj carbon ntau ntxiv, feem ntau yog li ntawm 0.18% mus rau 0.22%. Qhov no variant muab kev txhim kho lub zog thiab hardness piv rau Q355B. Q355C feem ntau yog siv rau hauv cov ntawv thov uas yuav tsum tau muaj peev xwm thauj khoom ntau dua, xws li cov tshuab hnyav, cranes, thiab cov qauv sab nrauv.
Q355D
Q355D steel yog hom Q355 nrog cov khoom siv kho kom zoo. Nws feem ntau muaj cov ntsiab lus carbon ntau dua thiab cov ntsiab lus alloying ntxiv xws li niobium, vanadium, lossis titanium. Q355D muaj lub zog zoo, toughness, thiab cuam tshuam tsis kam, ua rau nws tsim nyog rau kev thov cov qauv siv. Nws yog feem ntau ua hauj lwm nyob rau hauv kev tsim kho ntawm cov choj, cov tsev high-sawv, thiab cov yam ntxwv ntawm lub dynamic loads.
Q355E
Q355E steel yog lwm qhov sib txawv ntawm Q355 uas yog tsim los kom muaj cov khoom zoo dua qub. Nws nquag koom nrog cov hlau alloying xws li niobium, vanadium, lossis titanium kom nws lub zog thiab hardness. Q355E feem ntau yog siv rau hauv cov ntawv thov uas xav tau lub zog siab thiab ua haujlwm rau ib puag ncig, xws li offshore platforms, lub zog xa hluav taws xob, thiab cov khoom siv hnyav.
