GNEE Steel yog ib lub tuam txhab tsim thiab muab khoom lag luam uas tshwj xeeb hauv ASTM P22 seamless yeeb nkab, ntawm lwm yam khoom. Peb tab tom sim tsim cov khoom siv steel ntau yam uas muaj nqi thiab siv tau ntev. Peb muab cov khoom lag luam ntawm cov nqi sib tw rau qib P22, uas feem ntau yog siv thoob boiler raj thiab ntau lwm yam kev siv.
ASTM P22 yog ferric alloy steel ua rau qhov kub thiab txias ib puag ncig thiab muab kev tiv thaiv corrosion zoo nyob rau hauv qhov chaw zoo. Qib P22 muaj ntau yam ntaub ntawv uas tau ua tiav thiab muab rau peb cov neeg siv khoom, thiab cov no yog cov kav dej, cov raj, square kav, coiled raj, hydraulic raj, thiab lwm yam. Qib P22 yog chromium-molybdenum alloy zoo corrosion kuj tiv thaiv acidic tej yam kev mob thiab kuj muaj lub zog tensile siab ntawm qhov kub thiab txias. Feem ntau, cov kav hlau alloy muaj qhov sib npaug ntau dua li lwm cov qauv carbon steel nrog cov ntsiab lus alloying feem ntau yog molybdenum, chromium thiab npib tsib xee, thiab lwm yam. ASTM nthuav tawm cov hlau tsis tshua muaj hlau. Txawm li cas los xij, qhov sib ntxiv ntawm ntau dua ntawm cov ntsiab lus alloying (nickel thiab chromium) rov qab cov hlau rau hauv cov hlau alloy siab dua, tib yam li lwm cov hlau qib siab xws li Hastelloy, monel, thiab Inconel. Cov tshuaj muaj pes tsawg leeg hauv P22 seamless kav yog carbon 0.05-0.15%, manganese los ntawm 0.30-0.60%, silicon txog 1%, chromium mus txog 2.6%, thiab molybdenum thiab silicon zoo li lwm yam me me rau cov tshuaj sib npaug. 'Qhov sib ntxiv ntawm molybdenum ua rau kom muaj zog thiab yoog raws, thiab tseem txhim kho cov hlau tiv thaiv kev hnav thiab txhim kho nws cov khoom. Peb tsim seamless steel kav thiab raj los ntawm cov ntaub ntawv zoo raw khoom, thiab tag nrho peb cov khoom raug kuaj txaus ua ntej xa. Txhawm rau kom ntseeg tau tias peb cov neeg tau txais kev txaus siab, peb ua cov tshuaj ntsuam xyuas ib ntus ntawm cov kav hlau tsis muaj seamless thiab cov kav dej.
