ʻO CF3M a me CF8M ʻelua mau kila kila austenitic pili pili loa i hoʻohana nui ʻia i nā mea paʻi e like me nā valves., flanges, KahawaiOli, Nā'āpana'āpana, a me ka lako hana kemika.

No ka ʻohana ASTM A351 lāua ʻelua, ka mea e uhi ana i ka austenitic a me ka duplex kila hoolele no na apana paʻi a waiho i ka wae hope loa i ka mea kuai ma muli o ke kūlana lawelawe., nā koina mechanical, a me ka hana corrosion.

He wahi koʻikoʻi kēlā: ʻAʻole kēia he hana inoa inoa, akā he hoʻoholo ʻenekinia me nā hopena pololei no ka hilinaʻi, mālama, a me ke ola ola.

Ma kahi kiʻekiʻe, kaʻana like nā papa ʻelua i ka "platform" metallurgical - chromium, nickel, a me ka molybdenum - akā ʻokoʻa ka ʻike kalapona.

ʻO CF3M ka mana haʻahaʻa-carbon, ʻoiai ʻo CF8M e ʻae i ke kaupaku kalapona kiʻekiʻe.

Hoʻololi nui kēlā ʻano hoʻololi i ke ʻano o ka sensitization, weld-zone pōʻino pōʻino, a me ka nui o ka mana kaʻina hana e pono ai e mālama i ka ʻāpana i hilinaʻi ʻia i ka lawelawe koʻikoʻi.

1. Ka wehewehe kumu a me ka hoʻohālikelike: Nā kumu a me ka hoʻonohonoho kumu

ʻO ASTM A351 ka kikoʻī kikoʻī no kēia mau māka i ka hoʻoheheʻe ʻana i ke kaomi.

Ke hiki mai kēlā, lilo ka chromium i ka metala pili ma ka wahi, e hoʻonāwaliwali i ke kiʻiʻoniʻoni passive a hana i kahi ala palupalu no intergranur corrosior.

ʻO kēia ke kumu i manaʻo ʻia ai ʻo CF3M he koho ʻoi aku ka mālama ʻana no nā ʻāpana welded a thermally cycled..

Me ke kalapona i kaupalena 'ia 0.03% kiʻekiʻe, He emi loa ka ikaika o ka CF3M no ka ua carbide.
