ʻO ASTM A213 T9, i ʻike ʻia hoʻi ʻo ASME SA213 T9, he mea hana haʻahaʻa-metala ia.paipu kila humuhumuHoʻohana ʻia no nā paila, nā superheaters, a me nā mea hoʻololi wela.
He hui chromium-molybdenum ʻo T9 e loaʻa ana he 8.00–10.00% chromium a me 0.90–1.10% molybdenum. Loaʻa iā ia ka ikaika tensile liʻiliʻi o 415 MPa a me ka ikaika yield liʻiliʻi o 205 MPa. Me kona ikaika wela kiʻekiʻe maikaʻi loa, ke kū'ē'ē'ē'ē'ē, a me ke kū'ē'ē'ē'ē'ē, hana pono ʻo T9 ma lalo o nā kūlana hana wela kiʻekiʻe a me ke kaomi kiʻekiʻe.
Ma ke ʻano he mea hoʻolako paipu kila kila a me ka mea kūʻai nui ma Kina,Botop Steelhiki ke hoʻolako koke i kahi ākea o nā paipu kila T9 no kāu mau papahana, me ka hilinaʻi kūpono a me nā kumukūʻai hoʻokūkū.
Pono ka huahana i hāʻawi ʻia e ASTM A213 e kūlike me nā koi o ka Specification ASTM A1016, me nā koi pākuʻi i hōʻike ʻia ma ke kauoha kūʻai.

Mea Hana a me ke Kūlana
Pono nā paipu kila ASTM A213 T9 e hana ʻia ma ke kaʻina hana humuhumu ʻole a pono e hoʻopau wela ʻia a hoʻopau anu ʻia paha, e like me ka mea i kuhikuhi ʻia.
Ka Lapaʻau Wela
E hoʻomehana hou ʻia nā paipu kila T9 no ka mālama ʻana i ka wela e like me nā ʻano hana ma lalo nei, a e hana ʻia ka mālama wela ma ke kaʻawale a me ka hoʻomehana ʻana no ka hoʻokumu wela ʻana.
