Q235 ua haujlwm li cas hauv kev tsim cov khoom siv kho mob?
Weldability zoo heev. Nws qhov sib npaug ntawm cov pa roj carbon tsawg yuav txo qhov kev pheej hmoo ntawm kev tawg thaum lub sij hawm vuam, ua rau nws haum rau vuam thiab sib sau cov cuab yeej kho mob thiab kev txhawb nqa. Qib B thiab siab dua yog qhov tsim nyog rau cov qauv kho mob welded.
Qhov zoo li cas Q235's plasticity muab rau kev kho khoom siv?
Nrog rau qhov elongation ntawm kev tawg Ntau dua lossis sib npaug li 26%, nws tuaj yeem ua kom txias - khoov thiab stamped los tsim cov txheej txheem nyuaj rau cov khoom siv kho mob (xws li trolley thav duab thiab cov khoom siv plhaub), txo cov txheej txheem nyuaj.
Q235 puas ua tau raws li cov qauv kev tiv thaiv corrosion hauv cov chaw kho mob?
General corrosion kuj. Kev kho mob ib puag ncig (nrog rau cov tshuaj tua kab mob thiab cov dej noo) yog qhov ua rau xeb, yuav tsum tau kho deg (galvanizing, painting, passivation) ua ntej siv.
Puas muaj cov kev xav tau qib zoo rau Q235 siv hauv cov khoom siv kho mob?
Yog, Qib B thiab siab dua yog nyiam; Qib D (ua tau raws li cov qauv kev tiv thaiv toughness ntawm -20℃) raug xaiv rau qhov chaw kub qis (xws li cov khoom siv kho mob khaub thuas txias); Qib A yog txwv tsis pub rau cov qauv welded.
Puas yog qhov nyuaj ntawm Q235 haum rau cov khoom siv kho mob cov qauv? Nrog lub hardness ntawm 120-160 HBW, nws yog nruab nrab, ua kom muaj zog ntawm cov txheej txheem thaum pab txhawb kev ua haujlwm theem nrab xws li drilling, txiav, thiab sib tsoo, ua rau nws tsim nyog rau kev tsim cov khoom siv kho mob.
