ASTM A335 P92 ni iki?

ASTM A335 P92 (ASME SA335 P92) ni umuyoboro w'icyuma udafite umugozi ugenewe gukoreshwa mu bushyuhe bwinshi.Icyiciro cya UNS ni K92460.

P92 ni icyuma cya alloy gifite chromium martensitic nyinshi kandi kidashyuha kirimo chromium 8.50–9.50% kandi gikozwemo Mo, W, V, na Nb, gitanga imbaraga nziza zo gukurura ubushyuhe bwinshi, kirwanya oxidation, kandi kirwanya umunaniro w'ubushyuhe.

Ikoreshwa cyane mu miyoboro minini y’umwuka, mu miyoboro ishyushya umwuka, mu miyoboro ishyushya cyane n’ishyushya ya boilers z’amashanyarazi zikomeye cyane kandi zikomeye cyane, ndetse no mu miyoboro ishyushya cyane kandi ifite umuvuduko mwinshi ndetse n’ibice by’ingenzi bibungabunga umuvuduko mu nganda zitunganya peteroli n’izitunganya.

Ku bijyanye natwe

Botop Steel ni umucuruzi w’umwuga kandi wizewe w’imiyoboro y’ibyuma bya alloy mu Bushinwa, ushobora guha imishinga yawe vuba imiyoboro y’ibyuma by’ubwoko butandukanye, harimoP5 (K41545), P9 (K90941), P11 (K11597), P12 (K11562), P22 (K21590), naP91 (K90901).

Ibicuruzwa byacu bifite ubuziranenge bwizewe, igiciro cyabyo kiri mu irushanwa, kandi bishyigikira igenzura ry’abandi.

Imiterere ya mekanike

Imiterere yo Gufata

Icyiciro	Imiterere yo Gufata
Icyiciro	Imbaraga zo Gufata	Imbaraga z'umusaruro	Kurekura
ASTM A335 P92	90 ksi [620 MPa] min	iminota 64 ksi [440 MPa]	Iminota 20% (Uburebure)

ASTM A335 igaragaza agaciro k’uburebure bw’inyongera kabazwe kuri P92 kuri buri gabanuka rya 1/32 in. [0.8 mm] ry’ubugari bw’urukuta.

Ubunini bw'urukuta		Uburebure bwa P92 muri santimetero 2 cyangwa 50
in	mm	Indashyikirwa
0.312	8	Iminota 20%
0.281	7.2	Iminota 19%
0.250	6.4	Iminota 18%
0.219	5.6	Iminota 17%

0.062	1.6	Iminota 12%

Iyo ubugari bw'urukuta buri hagati y'agaciro kabiri kavuzwe haruguru, agaciro gato k'uburebure gagenwa n'uburyo bukurikira:

E = 32t + 10.00 [E = 1.25t + 10.00]

Aho:

E = uburebure muri mm 2 cyangwa 50, %, na

t = ubunini nyabwo bw'ibipimo, muri. [mm].

Ibisabwa ku bukomere

Icyiciro	Brinell	Vickers	Rockwell
ASTM A335 P92	250 HBW ntarengwa	265 HV ntarengwa	25 HRC ntarengwa

Ku miyoboro ifite ubugari bw'inkuta bwa santimetero 5.1 cyangwa zirenga, hagomba gukoreshwa ikizamini cyo gukomera cya Brinell cyangwa Rockwell.

Ikizamini cy'ubukana bwa Vickers kigomba gukorwa hakurikijwe Uburyo bwo Gupima E92.

Ikizamini cyo Kugorora

Ibizamini bigomba gukorwa ku bipimo byafashwe ku mpera imwe y'umuyoboro hakurikijwe ibisabwa n'Ingingo ya 20 ya ASTM A999.

Ikizamini cyo Kunama

Ku muyoboro ufite umurambararo urenze NPS 25 kandi ufite umurambararo ugereranyije n'ubugari bw'urukuta ari 7.0 cyangwa munsi yawo, ugomba gukorerwa isuzuma ry'uko ugonga aho gukora isuzuma ryo gufunga.

Ingero z'ibizamini byo kugonda zigomba kunama ku bushyuhe bw'icyumba kugeza kuri dogere 180 nta gucika inyuma y'igice cyagondamye.

Gukora no Gutunganya Ubushyuhe

Uruganda n'imiterere yarwo

imiyoboro y'icyuma ya ASTM A335 P92 igomba gukorwa nainzira idahindagurikakandi bigomba kuba bishyushye cyangwa bikonje, nk'uko byavuzwe.

Umuyoboro udafite imigozi ni umuyoboro udafite imigozi. Mu bidukikije birimo ubushyuhe bwinshi n'umuvuduko mwinshi, imiyoboro idafite imigozi ishobora kwihanganira umuvuduko mwinshi w'imbere n'ubushyuhe, igatanga imiterere myiza y'imiterere n'imiterere ya mekanike, kandi ikirinda inenge zishobora kubaho ku migozi y'imigozi.

Uburyo bwo kuvura ubushyuhe

Umuyoboro wa P92 ugomba kongera gushyushywa kugira ngo ushyushye kandi utunganywe hakurikijwe ibisabwa.

Icyiciro	ASTM A335 P92

Ubushyuhe bupima	1350 ~ 1470 ℉ [730 ~ 800 ℃]

Ibyuma bimwe na bimwe bya ferritic bikubiye muri ubu buryo bizakomera iyo bikonjeshejwe vuba bivuye hejuru y'ubushyuhe bwabyo bukomeye. Bimwe bizakomera mu mwuka, ni ukuvuga ko bizakomera ku rugero rudakwiye iyo bikonjeshejwe mu mwuka bivuye ku bushyuhe bwinshi.

Kubwibyo, ibikorwa birimo gushyushya ibyuma nk'ibyo hejuru y'ubushyuhe bwabyo bukomeye, nko gusudira, gukurura no gushyushya, bigomba gukurikirwa no gutunganya ubushyuhe bukwiye.
