A: Qhov tsawg kawg nkaus yield zog ntawm Q235 phaj yog 235 MPa (rau cov phaj nrog thickness tsawg dua los yog sib npaug rau 16 hli).
Q: Lub zog tensile ntau ntawm Q235 phaj yog dab tsi?
A: Lub zog tensile ntawm Q235 phaj yog 375 ~ 500 MPa.
Q: Qhov tsawg kawg nkaus elongation tus nqi ntawm Q235 phaj yog dab tsi?
A: Rau daim hlau nrog thickness Tsawg dua los yog sib npaug rau 16 hli, qhov tsawg kawg nkaus elongation tus nqi yog 26%. Nrog rau qhov nce ntawm phaj thickness, elongation tus nqi yuav tsum tau txo kom tsim nyog.
Q: Puas yog Q235 phaj yuav tsum xeem dhau qhov kev sim?
A: - Q235A: Tsis muaj qhov yuav tsum tau kuaj xyuas.
Q235B: Kev sim cuam tshuam ntawm 20 degree, yam tsawg kawg nkaus lub zog 27J.
Q235C: Kev sim cuam tshuam ntawm 0 degree, yam tsawg kawg nkaus lub zog 27J.
Q235D: Kev sim cuam tshuam ntawm -20 degree, yam tsawg kawg nkaus lub zog 27J.
Q: Dab tsi yog qhov hardness ntau ntawm Q235 phaj?
A: Lub Brinell hardness (HB) ntawm Q235 phaj feem ntau yog nyob nruab nrab ntawm 120 ~ 160, uas yog ib tug kuj mos hlau phaj.
Q: Ua li cas lub thickness ntawm Q235 phaj cuam tshuam rau nws lub zog tawm los?
A: Nrog rau qhov nce ntawm phaj thickness, lub zog tawm los ntawm Q235 phaj yuav txo qis. Piv txwv li, lub zog tawm los ntawm daim hlau nrog thickness 16 ~ 40mm yog 225 MPa, thiab cov phaj thickness 40 ~ 60mm yog 215 MPa.
