A335 P92 Chrome Moly Alloy Seamless Yeeb Nkab
A335 P92 American standard alloy seamless steel yeeb nkab yog siab -kub, siab -siab alloy seamless steel yeeb nkab tsim raws li American Society for Testing and Materials (ASTM) tus qauv. "A335" nyob rau hauv nws lub npe sawv cev rau cov series ntawm chromium-molybdenum alloy steel kav, thaum "P92" qhia cov khoom qib. Cov yeeb nkab steel no feem ntau yog ua los ntawm cov qib siab - zoo alloy steel, nrog rau cov khoom tseem ceeb xws li chromium, molybdenum, vanadium, niobium, thiab lwm yam. Los ntawm cov txheej txheem smelting thiab kev kho cua sov (xws li quenching thiab tempering), lub microstructure ruaj khov yog tsim, ua rau muaj kev kub siab zoo heev, oxidation tsis kam, thiab creep resistance.

P92 belongs rau 9Cr-1Mo-V-Nb-W series ntawm martensitic thaum tshav kub kub-resistant steels, thiab yog siab- alloy khoom optimized thiab upgraded raws li P91 steel. Nws cov qauv tsim tseem hloov pauv ib feem ntawm molybdenum (Mo) nrog tungsten (W) thiab ntxiv cov lej ntawm boron (B) thiab niobium (Nb) los tsim cov theem ruaj khov nanoscale carbonitride ntxiv dag zog rau theem, txhim kho qhov kub thiab txias creep zog thiab oxidation tsis kam.
P92 seamless steel kav nruj me ntsis ua raws li ASTM A335 / A335M-23 (Specification for Ferritic Alloy Steel Seamless Pipes for High-Temperature Applications), xav tau kev kho cua sov dual ntawm normalizing thiab tempering los xyuas kom meej tias cov lath martensite cov ntsiab lus nyob rau hauv lub microstructure tsis sib npaug ntawm 9% thiab kev sib npaug kuaj xws li ultrasonic tsis pom kev thiab muaj CT imaging. Qee daim ntawv thov kuj yuav tsum ua raws li cov qauv hauv cheeb tsam xws li EN 10216-2 thiab GB / T 5310.
