Qhov txawv ntawm Q235B welded yeeb nkab thiab Q235A welded yeeb nkab
- Hauv kev lag luam ntawm cov ntaub ntawv hlau, Q235 yog cov khoom siv dav dav siv cov pa roj carbon zoo tib yam, tseem hu ua qib qub ntawm A3 steel. Yuav kom nkag siab txog qib Q235, peb yuav tsum xub qhia meej tias Q sawv cev rau lub zog tawm los, thaum 235 qhia nws lub zog ntawm 235 MPa. Txawm li cas los xij, thaum peb hla cov ntsiab lus zoo li Q235A thiab Q235B, peb txhais li cas?
- Cov ntsiab lus carbon ntawm Q235A thiab Q235 txawv me ntsis, nrog Q235A muaj nyob nruab nrab ntawm 0.14% thiab 0.22%, thiab Q235 muaj nruab nrab ntawm 0.12% thiab {{10} }.20% Qhov sib txawv ntawm qhov tseem ceeb ntawm A thiab B yog qhov tseeb ntawm qhov sib txawv ntawm cov qib ntawm cov khoom siv yeeb nkab steel, uas yog qhov tseem ceeb ntawm cov kev xav tau sib txawv ntawm qhov kub thiab txias. Tshwj xeeb, Q235A tsis raug kuaj xyuas, thaum Q235B yuav tsum muaj kev cuam tshuam los ntawm 20 degrees ambient kub.
- Hais txog cov khoom siv kho tshuab, Q235B steel yeeb nkab kev ua tau zoo yog qhov zoo dua li Q235A steel yeeb nkab. Piv txwv li, nyob rau hauv cov khoom steel xws li cov ces kaum, raws, I-beams, H-beams, thiab lwm yam., lub zog thiab toughness ntawm Q235B steel yog zoo heev. Yog li ntawd, thaum yuav cov kav hlau steel, cov neeg siv khoom yuav tsum xaiv cov khoom tsim nyog raws li cov ntawv thov tshwj xeeb thiab cov kev xav tau ntawm kev cuam tshuam.
- , Q235 belongs rau qeb ntawm cov pa roj carbon tsawg thiab yog cua sov kho. Txawm li cas los xij, vim nws cov ntsiab lus tsis tshua muaj carbon, kev kho cua sov tuaj yeem txhim kho qhov hardness txwv, cov nyhuv tsis tseem ceeb. Nyob rau tib lub sijhawm, kev saib xyuas yuav tsum tau them nyiaj rau kev tiv thaiv steel deformation thiab tawg thaum lub sijhawm kho cua sov.
