A335 / SA335 Qib P22 Alloy Steel Seamless Pipes yog Carbon steel kav nrog ntxiv ntawm chromium, molybdenum, thiab qee zaum vanadium. Chromium, los yog chrome, txhim kho qhov kub thiab txias zog, nce oxidation tsis kam thiab nce lub tensile, tawm los thiab hardness ntawm chav tsev kub. Molybdenum nce lub zog, elastic txwv, tsis kam hnav, cuam tshuam zoo thiab hardenability. Nws tsub kom qhov tsis kam mus softening, txwv kev loj hlob grain thiab ua rau chromium hlau tsis tshua muaj embrittlement. Moly kuj yog qhov zoo tshaj plaws additive rau kev kub siab creep zog, los yog creep kuj, thiab nws kuj txhim khu cov corrosion kuj ntawm hlau thiab inhibits pitting. Qib P22 yog siv rau cov ntawv thov kev pabcuam kub thiab ua siab ntev rau kev hloov pauv hauv nws cov microstructure.
