    ASTM A335 P.9 ni icyuma kivanze kitagira ferritic yubushyuhe bwo hejuru bwa Amerika. Alloy tube ni ubwoko bwicyuma kitagira icyuma, imikorere yacyo irarenze cyane icyuma rusange kitagira icyuma, kubera ko ubu bwoko bwicyuma burimo C nyinshi, imikorere ntabwo iri munsi yicyuma gisanzwe kidafite icyuma, bityo umuyoboro wa alloy ukoreshwa cyane muri peteroli, ikirere, icyogajuru, amashanyarazi, amashyiga, igisirikare nizindi nganda.

    A335 P9ni ubushyuhe bwo hejuru bwa chromium-molybdenum alloy ibyuma birwanya ubushyuhe bikozwe ukurikije igipimo cyabanyamerika. Kubera imbaraga za okiside nziza cyane, imbaraga zubushyuhe bwo hejuru hamwe na sulfide irwanya ruswa, ikoreshwa cyane mubushyuhe bwo hejuru hamwe numuvuduko mwinshi utwika kandi uturika wibiti bitunganya ibikomoka kuri peteroli, cyane cyane umuyoboro wubushyuhe utaziguye w’itanura, ubushyuhe bwo hagati burashobora kugera kuri 550 ~ 600 ℃ .
