ASTM A335 / ASME SA335 yog cov qauv kev qhia tshwj xeeb rau seamless ferritic alloy steel raj uas siv rau hauv kev pabcuam kub (540 - 750 ° C) thiab hauv kev lag luam boiler. Cov yeeb nkab yuav tsum tsim nyog rau kev khoov, flanging (flipping), thiab kev ua haujlwm zoo sib xws, thiab rau fusion vuam.
Gnee Steel yog cov chaw tsim khoom, xa tawm thiab cov chaw muag khoom ntawm ASTM A335 P22 Alloy Steel Tubes. Qhov zoo ntawm Alloy Steel P22 Seamless Pipes suav nrog nws txoj kev nruj, kev ua haujlwm zoo, tsis kam ua rau qaug zog, ua haujlwm ntev thiab hnav tsis kam. ASME Alloy Steel Yeeb Nkab yog siv rau cov ntawv thov kev pabcuam kub. Alloy steel seamless yeeb nkab ua raws li ASME SA 335 Qib P22 yog rov ua dua thiab muab tso rau hauv kev ncua qeeb, isothermally tempered, lossis cov qauv tempered.
ASME SA335 P22 Alloy Steel Seamless Pipes yog carbon steel kav, A335 feem ntau hu ua chrome moly yeeb vim yog cov tshuaj muaj pes tsawg leeg ntawm molybdenum (Mo) thiab chromium (Cr). Molybdenum nce lub zog ntawm cov hlau, nrog rau kev tawm dag zog, hnav tsis kam, cuam tshuam zoo, thiab hardenability. Moly tsub kom tsis kam mus rau softening, txwv tsis pub cov qoob loo loj hlob, thiab ua rau chrome hlau tsis tshua muaj embrittlement. Moly yog ib qho zoo tshaj plaws additive uas ua rau kom kub siab creep kuj.
