Lub ntsiab alloy Cheebtsam ntawm A335 P92 boiler raj yog Cr: 9%, Mo: 1%, thiab lwm yam lub caij, thiab ntxiv ib qho nyiaj ntawm W, uas nce qhov sib npaug molybdenum (Mo+0.5W) ntawm cov khoom los ntawm 1% ntawm P91 steel mus txog 1.5%. Kev kub siab lub zog thiab creep zog yog txhim kho. Qhov no ua rau nws siv tau rau hauv cov chav ultra-supercritical thiab ib puag ncig siab tshaj 600 degrees Celsius.
A335 P92 high-pressure boiler raj yog tsim rau khoov, curling thiab zoo sib xws txheej txheem raws li fusion vuam, thiab xaiv tau raws li tus tsim, ua hauj lwm tej yam kev mob, mechanical zog thiab kub yam ntxwv.
