ASTM A335 P92 Alloy Steel Tubes

A335 P92 alloy yeeb nkab, P92 khoom yog American steel tooj ASTM A335 P92, uas yog martensitic tshav kub-resistant steel. Nws yog feem ntau siv nyob rau hauv thermal fais fab nroj tsuag, feem ntau nyob rau hauv lub ntsiab chav kav thiab reheat chav kav. Lub ntsiab alloy Cheebtsam yog Cr: 9%, Mo: 1%, thiab lwm yam.
P92 Alloy Steel Seamless Yeeb Nkab muaj qhov zoo tshaj plaws kub-kub corrosion thiab oxidation kuj nyob rau hauv ultra-supercritical units thiab high-temperature puag ncig saum 600 degrees Celsius, thiab nws high-temperature zog thiab creep zog kuj tau txhim kho. Yog li ntawd, ASTM A335 P92 seamless steel kav yog dav siv nyob rau hauv cov ntsiab lus tseem ceeb xws li lub ntsiab chav kav thiab reheat chav kav ntawm thermal fais fab nroj tsuag.
Ua raws li tus qauv ASTMA335 / A335M
SA-335 P92 Kev kub siab alloy steel yeeb nkab yog raws li SA-335P91 steel yeeb nkab, tsim nyog txo cov ntsiab lus ntawm Mo, thiab ntxiv ib qho nyiaj ntawm W los hloov molybdenum sib npaug ntawm cov khoom (Mo +0.5W) los ntawm P91 steel. 1% yog nce mus txog 1.5%. Cov hlau kuj ntxiv ib qho kab ntawm boron. Tom qab kev txhim kho alloying saum toj no, piv nrog rau lwm cov khoom siv hluav taws xob-resistant steels nyob rau hauv 9% Cr series, nws cov high-temperature corrosion kuj thiab oxidation kuj zoo sib xws, tab sis kub siab zog thiab creep zog yog zoo dua.
