ASTM A213 T12 yeeb nkab yog tsim los ntawm carbon, manganese, phosphorus, sulfur, silicon, yam tsawg kawg yog 0.8% chromium thiab 0.44% molybdenum nrog qhov tsawg kawg nkaus yield zog ntawm 205MPa thiab lub zog tensile yam tsawg kawg nkaus. ntawm 415 MPa.
Ntawm lawv, ASTM A213 T12 alloy steel seamless yeeb nkab yog siv ntau tshaj vim nws qhov ntev. Cov yeeb nkab loj yuav txawv raws li ASTM, ASME, thiab API cov qauv.
Phab ntsa thicknesses li ntawm 1 hli mus rau 200 hli, ntev mus txog 2500 hli, thiab sab nraud diameters los ntawm 1/2 nti mus rau 5 nti.
ASTM A213 Qib T12 yeeb nkab tuaj yeem kho cua sov siv tag nrho lossis isothermal annealing lossis normalizing thiab tempering txoj kev. Cov txheej txheem vuam tsoos tsis tas yuav tsum tau preheating, tab sis thaum siv oxyacetylene vuam lossis submerged arc vuam, cov khoom yuav tsum tau preheated thiab tom qab vuam kub kho.
