Q195 steel yog dab tsi?
Q195 yog cov pa roj carbon monoxide zoo tib yam, yog nyob rau hauv qeb qis - carbon steel, thiab ua raws li lub teb chaws tus qauv GB / T 700. "Q" sawv cev rau lub zog tawm los, thiab "195" txhais tau hais tias lub zog tawm los yog ntau dua lossis sib npaug rau 195MPa thaum lub thickness tsawg dua lossis sib npaug li 16 hli.
Dab tsi yog qhov tseem ceeb mechanical zog ntawm Q195?
Yield zog: Ntau dua los yog sib npaug rau 195MPa rau Tsawg dua lossis sib npaug rau 16mm; Ntau tshaj lossis sib npaug ntawm 185MPa rau 16-40mm
Tensile zog: 315-430MPa
Elongation: Ntau dua lossis sib npaug li 33% rau Tsawg dua lossis sib npaug li 16 hli; Ntau tshaj lossis sib npaug li 32% rau 16-40mm
Dab tsi yog cov yam ntxwv ntawm cov tshuaj muaj pes tsawg leeg ntawm Q195?
Cov ntsiab lus carbon tsawg dua lossis sib npaug li 0.12%, muaj cov manganese, silicon, sulfur, thiab phosphorus me me. Nws yog qis-carbon thiab qis- alloy steel, kom ntseeg tau zoo plasticity thiab weldability.
Dab tsi yog qhov txawv ntawm Q195 thiab Q235 thiab Q345? Lub zog nce ntxiv (Q195 < Q235 < Q345). Q195 muaj qhov zoo tshaj plaws plasticity thiab weldability, thiab tus nqi qis tshaj plaws, ua rau nws tsim nyog rau cov ntawv thov tsawg-; Q235/Q345 yog siv rau kev thauj khoom{11}}cov kabmob.
Dab tsi yog cov qhab nia thoob ntiaj teb sib xws rau Q195?
ISO: HR2; ASTM: Gr.B; JIS: SS330; DIN: St33.
