ASTM A515 Qib 60
Lub zog: qis qis tensile thiab tawm lub zog.
Mechanical Properties: Tensile zog ~ 415-550 MPa (60-80 ksi), Yam tsawg kawg nkaus tawm ~ 207 MPa (30 ksi).
Ductility: Siab elongation (ntau dua ductile).
Qhov zoo tshaj plaws rau: Cov ntawv thov tsawg dua uas xav tau ntau dua ductility.
ASTM A515 Qib 65
Lub zog: siab dua tensile thiab tawm lub zog.
Mechanical Properties: Tensile zog ~ 450-590 MPa (65-85 ksi), Yam tsawg kawg nkaus tawm ~ 241 MPa (35 ksi).
Ductility: Tsawg elongation me ntsis (tsawg dua ductile dua Gr. 60).
Qhov Zoo Tshaj Plaws Rau: Nruab Nrab -kev pabcuam kub thiab siab dua- cov ntawv thov kev ntxhov siab uas xav tau lub zog sib npaug.
