ASTM A387 Qib 11 Chav Kawm 2 Hlau Phaj yog dab tsi?
ASTM A387 Qib 11 Chav Kawm 2yog chromium-molybdenum (Cr-Mo) alloy steel phaj tsim rau siab -kub siab cov hlab ntsha. Ua raws li ASTM A387 / A387M cov qauv, cov hlau no muaj 1.00-1.50% chromium thiab 0.45-0.65% molybdenum, muab kev nkag tau zoo heev, tiv thaiv corrosion, thiab kav ntev.
Muab xa mus rau hauv lub xeev zoo li qub thiab tempered nrog qhov kub thiab txias ntawm 620 degree, A387 Gr 11 Cl.2 daim hlau muaj:
- Tensile zog: Ntau dua los yog sib npaug rau 440 MPa
- Yield zog: Ntau dua los yog sib npaug rau 295 MPa
- Lub zog cuam tshuam: Ntau dua lossis sib npaug rau 94 J
Piv nrog rau Chav Kawm 1 daim hlau, Chav Kawm 2 ua tiav lub zog ntau dua los ntawm cov txheej txheem kev kho cua sov, ua rau nws zoo tagnrho rau cov tshuab hluav taws xob, cov khoom siv hluav taws xob, thiab lwm yam khoom siv tseem ceeb.
