ASTM A633 HSLA hlau
Cov khoom no yog tshwj xeeb tshaj yog haum rau cov kev pab cuam nyob rau hauv qis ambient kub ntawm -50oF [-45oC] thiab siab dua qhov twg notch toughness zoo tshaj qhov xav tau nyob rau hauv as-rolled khoom ntawm ib tug sib piv lub zog yog xav tau.
Plaub qib, xaiv Qib A, C, D, thiab E (qhov tseem ceeb yav dhau los Specification A633 yam tsis muaj kev xaiv qib) yog them los ntawm cov lus qhia no.
Qib A muab qhov ntsuas qhov tsawg kawg nkaus ntawm 42 ksi [290 MPa] hauv thicknesses txog 4 in. [100 mm], suav nrog.
Qib C thiab D muab qhov ntsuas qhov tsawg kawg nkaus ntawm 50 ksi [345 MPa] hauv thicknesses txog 2.50 in. [65 mm], suav nrog thiab 46.0 ksi [315 MPa] hauv thicknesses tshaj 2.50 in. to 4.0 in. [65 mus rau 100 mm], suav nrog.
Qib E muab qhov ntsuas qhov tsawg kawg nkaus ntawm 60 ksi [415 MPa] hauv thicknesses txog 4.0 in. [100 mm], suav nrog thiab 55 ksi [380 MPa] hauv thicknesses tshaj 4 in. mus rau 6 in. [100 mus rau 150 mm], suav nrog.
ASTM A633 Qib A yog dab tsi?
290 MPa rau
A633 Qib A muaj qhov tsawg kawg nkaus tawm lub zog ntawm 42 ksi [290 MPa]
