Q235 steel yog dab tsi?
Q235 yog carbon steel qauv. "Q" sawv cev rau lub zog tawm los, thiab "235" qhia tias lub zog tawm los ≥ 235 MPa. Nws ua raws li lub teb chaws tus qauv GB / T 700-2006 thiab muaj nyob rau hauv plaub qib zoo: A, B, C, thiab D.
Dab tsi yog cov khoom tseem ceeb ntawm Q235?
Carbon (C: 0.12%-0.20%), Silicon (Si: ≤0.30%), Manganese (Mn: 0.30% -0.70%), Sulfur (S: ≤0.045%), Phosphorus (P: ≤0.045%). Nws cov qauv tsim qis-carbon ua kom zoo plasticity thiab weldability.
Dab tsi yog cov khoom tseem ceeb ntawm Q235?
Yield zog ≥235MPa, tensile zog 375-500MPa, elongation tom qab tawg ≥26%, Brinell hardness 120-160HBW, Class D - 20℃cuam tshuam lub zog ≥27J.
Vim li cas kev lag luam kho mob xaiv Q235?
Nws muaj tus nqi siab -kev ua tau zoo, kev ua tau zoo, weldability zoo heev, thiab lub zog uas ua tau raws li cov qauv kev xav tau ntawm cov khoom siv kho mob uas tsis yog-implantable, ua rau nws tsim nyog rau kev tsim khoom siv kho mob thav duab, stents, thiab tsis yog - tiv tauj cov khoom.
Dab tsi yog daim ntawv thov ciam teb ntawm Q235 hauv kev lag luam kho mob?
Nws yog nruj me ntsis txwv tsis pub siv rau hauv tib neeg implantation, kev sib cuag ncaj qha nrog cov tshuaj tsis muaj menyuam / ntshav, los yog ib puag ncig kev kho mob corrosive heev. Nws tsuas yog tsim nyog rau cov qauv ntawm cov khoom siv kho mob uas tsis cuam tshuam ncaj qha rau tib neeg lub cev.
