Ububiko butagira ibyumaASTM A335 P91, umuyoboro wicyuma udafite ubudodo ukoreshwa mubituba, ibyuma bihinduranya ubushyuhe nizindi nganda, birashobora gukoreshwa nkumuyoboro wibyuma byubushyuhe bwo hejuru nubushyuhe bwo hejuru mubushyuhe bwo hejuru hamwe nubushyuhe bukabije hamwe nubushyuhe bwurukuta ≤625 ° C, hamwe nurukuta Imitwe yubushyuhe bwo hejuru n'imiyoboro ihumeka hamwe n'ubushyuhe ≤600 ℃ irashobora kandi gukoreshwa nk'ingufu zoguhindura ingufu za kirimbuzi hamwe na peteroli yamashanyarazi.
ASTM A335 P91 nicyuma cyubushyuhe bwo hejuru cyane nicyuma cya chromium-molybdenum.Ikoreshwa cyane mu miyoboro n'ibikoresho munsi yubushyuhe bwinshi hamwe n’umuvuduko ukabije w’ibidukikije, nka peteroli, amashanyarazi, amashanyarazi, ingufu za kirimbuzi n’izindi nzego.Ibice byingenzi bigize ibi bikoresho ni chromium, molybdenum, umuringa, manganese, silikoni, fosifore, sulfure nibindi bintu.Ibiri muri chromium na molybdenum ni byinshi cyane, bishobora kuzamura ubushyuhe bwo hejuru no kurwanya okiside yibikoresho.
ASTM A335 P91 ibikoresho bifite imiterere yubukanishi kandi birashobora gukomeza imbaraga nubukomezi munsi yubushyuhe bwinshi nibidukikije.Ibikoresho kandi birwanya cyane okiside, ishobora kongera ubuzima bwa serivisi yimiyoboro nibikoresho.Mubyongeyeho, ibikoresho nabyo bifite imikorere myiza yo gusudira, bigatuma kubaka no kubungabunga byoroha.
Kuberako ibikoresho bya ASTM A335 P91 bifite iyi mico myiza, ikoreshwa cyane mubushyuhe bwo hejuru hamwe n’umuvuduko mwinshi.Kurugero, mu nganda zikomoka kuri peteroli, imiyoboro nibikoresho bikozwe muri ASTM A335 P91 birashobora guhangana n’isuri y’imiti no kwangirika mu gihe cy’ubushyuhe bwinshi n’umuvuduko, bigatuma ibikoresho bikoreshwa neza.Mu rwego rw'amashanyarazi n'amashanyarazi ya kirimbuzi, imiyoboro n'ibikoresho bikozwe muri ASTM A335 P91 birashobora kwihanganira kwangirika no gutwarwa n'umwuka w'amazi n'amazi hamwe n'ibindi bitangazamakuru mu bushyuhe bwinshi n'umuvuduko, bigatuma imikorere isanzwe ikoreshwa.
