ASTM A335 P22 yeeb nkab yog seamless ferritic alloy steel yeeb nkab rau kev pabcuam kub. Cov yeeb nkab xaj raws li qhov tshwj xeeb no yuav tsum tsim nyog rau kev khoov, flanged (vanstoning) thiab kev ua haujlwm zoo sib xws, thiab rau fusion vuam. Qee lub sij hawm hu ua "P Qib", chome moly tubing yog nrov hauv qib P5, P9, P11, P22 thiab P91. Kev siv ntau tshaj ntawm qib P11, P22 thiab P91 yog nyob rau hauv kev lag luam fais fab thiab cov nroj tsuag petrochemical, qib P5 thiab P9 feem ntau yog siv rau hauv refineries.
A335 feem ntau hu ua chrome moly tubing, vim cov tshuaj muaj pes tsawg leeg ntawm molybdenum (Mo) thiab chromium (Cr). Molybdenum nce lub zog ntawm cov hlau, nrog rau cov khoom muaj zog, hnav tsis kam, cuam tshuam zoo, thiab hardenability. Moly tsub kom tsis txhob softening, txwv tsis pub cov nplej loj hlob, thiab ua rau chrome hlau tsis tshua muaj embrittlement. Moly yog ib qho khoom siv zoo tshaj plaws uas ua rau kom nkag siab tsis kam ntawm qhov kub thiab txias. Nws kuj txhim kho corrosion kuj ntawm steel thiab inhibits pitting. Chromium (los yog chromium) yog qhov tseem ceeb ntawm cov hlau tsis muaj steel. Cov hlau uas muaj 12 feem pua lossis ntau dua chromium yog suav tias yog stainless. Chromium yog zoo irreplaceable nyob rau hauv tiv thaiv oxidation ntawm siab kub. Chromium nce traction, kev ua tau zoo thiab toughness ntawm chav tsev kub. Cov muaj pes tsawg leeg ntawm milled chromium alloy steel yeeb nkab ua rau nws zoo tagnrho rau siv nyob rau hauv fais fab nroj tsuag, refineries, petrochemical nroj tsuag thiab roj teb cov kev pab cuam qhov twg cov kua thiab gases yog thauj ntawm tsis tshua muaj kub thiab siab.
