Dab tsi yog cov khoom xyaw tseem ceeb (%) ntawm Q195?
C≤0.12, Mn≤0.50, Si≤0.30, P≤0.035, S≤0.040, nrog rau qhov seem yog Fe.
Vim li cas cov ntsiab lus carbon ntawm Q195 tswj tau ≤0.12%?
Cov ntsiab lus carbon tsawg ua kom cov yas zoo heev, ua haujlwm txias, thiab weldability, tsis txhob weld tawg thiab ua haujlwm hnyav heev.
Dab tsi yog qhov txwv sab sauv rau leej faj thiab phosphorus impurities hauv Q195?
P≤0.035%, S≤0.040%. Tsawg impurities txhim kho toughness thiab ua stability.
Q195 puas muaj cov ntsiab lus alloying?
Tsis yog, nws tsis muaj kev txhob txwm ntxiv cov ntsiab lus alloying. Nws yog cov pa roj carbon zoo tib yam nrog tus nqi qis.
Cov tshuaj muaj pes tsawg leeg hloov pauv ntawm Q195 cuam tshuam rau nws qhov kev ua tau zoo li cas?
Cov ntsiab lus carbon siab nce lub zog tab sis txo cov yas; Cov ntsiab lus sulfur thiab phosphorus ntau dhau tau yooj yim ua rau cov kab mob khaub thuas bending thiab vuam tsis xws luag.
