ASTM A213 T9, tseem hu ua ASME SA213 T9, yog cov hlau tsis tshua muaj hlauseamless hlau rajsiv rau boilers, superheaters, thiab cov cua sov sib hloov.
T9 yog ib qho hlau chromium-molybdenum uas muaj 8.00–10.00% chromium thiab 0.90–1.10% molybdenum. Nws muaj lub zog tensile tsawg kawg nkaus ntawm 415 MPa thiab lub zog yield tsawg kawg nkaus ntawm 205 MPa. Nrog nws lub zog zoo heev thaum kub siab, tiv taus oxidation, thiab tiv taus creep, T9 ua haujlwm tau zoo nyob rau hauv qhov kub siab thiab siab siab ua haujlwm.
