A312 Seamless steel raj tshuaj siv hluav taws xob:
ASTM A312yog ib qho tsis yog-alleoy qauv hlau hauv qab European tus qauv, sib npaug nrog Suav qauv Q235b. Nws cov tshuaj lom neeg muaj pes tsawg leeg suav nrog cov ntsiab lus carbon (c) ntawm tsawg dua lossis sib npaug ntawm {}. 65%, phosphorus cov ntsiab lus (p) ntawm tsawg dua lossis sib npaug 0. {0 30%, thiab Sulfur Cov Ntsiab Lus (s) ntawm tsawg dua lossis sib npaug rau 0.030%.
ASTM A312 Seamless Steel Tube cov yam ntxwv:
Cov txiaj ntsig lub zog yog ntau dua los yog sib luag rau 235 MPa, thaum lub zog tensile nyob nruab nrab ntawm {}} mpa. Lub elongation loj dua los yog sib npaug rau 18%, ua kom pom kev zoo thiab weldability. Nws tuaj yeem tiv taus ib qho degree ntawm deformation tsis muaj fracturing.
