Mechanical zog (t Tsawg dua los yog sib npaug rau 16mm)?
Yield zog ** Ntau dua lossis sib npaug rau 345MPa **; Tensile zog 470-630MPa; Elongation ** Ntau dua lossis sib npaug li 21% **; Dhau 180℃txias dabtsi yog khoov kuaj.
Puas muaj zog hloov nrog tuab?
Yog lawm. Qhov ntau dua qhov tuab, qhov qis dua lub zog tawm los:
16-35mm: Ntau dua lossis sib npaug rau 335MPa
35-50mm: Ntau dua lossis sib npaug rau 325MPa
50-100mm: Ntau dua lossis sib npaug rau 295MPa
Qhov txawv ntawm Q345 thiab Q235?
Lub zog: Q345 tawm lub zog yog li 50% siab dua.
Muaj pes tsawg leeg: Q345 muaj Mn (1.0–1.6%), Q235 yog tsawg hauv manganese.
Daim ntaub ntawv: Q345 yog siv rau hnyav- lub luag haujlwm / dynamic loads (bridges, crane nqaj); Q235 yog siv rau cov qauv dav dav.
Kev sib raug zoo ntawm Q345 thiab Q355?
Q355 yog qhov hloov kho tshiab rau Q345 (muaj txiaj ntsig los ntawm Lub Ob Hlis 1, 2019). Qhov sib txawv tseem ceeb:
Q355 yield zog ** Ntau dua lossis sib npaug rau 355MPa **
S thiab P tswj tau nruj dua, ua rau muaj qhov zoo dua -kub toughness.
Puas yog 16Mn zoo ib yam li Q345?
Yog. 16Mn (qib qub)=Q345 (qib tshiab), nrog rau qhov tseem ceeb tib yam muaj pes tsawg leeg thiab cov khoom.
