Dec 05, 2025
ASTM A213 T11 Seamless alloy tubes piav qhia
T11 Alloy Tubesyog cov tshwj xeeb siab -alloy steel kav cais raws limartensitic tshav kub-resistant steel, feem ntau yog siv nyob rau hauv siab - qhov kub thiab txias ib puag ncig xws li cov cua kub exchangers thiab boiler piping.
Tshuaj muaj pes tsawg leegmuaj xws li carbon (C), silicon (Si), manganese (Mn), phosphorus (P), sulfur (S), thiab alloying ntsiab xws li chromium (Cr), molybdenum (Mo), thiab vanadium (V). Cov ntsiab lus siab Cr/Mo txhim kho corrosion kuj, siab - kub stability, thiab txhua yam khoom, thaum V txhim kho toughness.
Mechanical Properties:
Siab zog / hardness nrog zoo toughness
Tshaj tawm -cov nqi kho cua sov:
Tensile zog:Ntau dua lossis sib npaug li 450 MPa
-Yield zog:Ntau dua lossis sib npaug li 300 MPa
-Hardness:Ntau dua lossis sib npaug li 200 HB
Zoo heev qaug zog thiab corrosion kuj
Kev kho cua sov:
Quenching: ~ 900℃(tuav 2h) → cua txias
Tempering: ~ 650℃(tuav 2h) → cua txias
Qhov tshwm sim microstructure:Tempered martensitexa balanced mechanical zog.
