Hiki ke kū'ē i ka papa 347/347H
Hāʻawi kēia mau māka i ka nui o ka pale ʻana i ka corrosion e like me nā māka chromium paʻa.Loaʻa iā ia ka hiki ke kū'ē i ka corrosion āpau āpau.ʻO ka mea maʻamau, he papa SS i hoʻopaʻa ʻia e hāʻawi i ke kūpaʻa maikaʻi loa i ka corrosion intergranular i ka ʻike ʻana i nā wela kiʻekiʻe.He mea kū'ē i ka chromium carbide laula o ka ua ( sensitization ) i ka mahana 427 a i 816 degere C. Ua hoʻopaʻa kūʻē i ka hana chromium carbide.
Hiki i ka Alloy 347/347H ke pilikia i ka pohā ʻino (SSC) i nā kaiapuni halides.ʻO kēia ma muli o kona ʻano nickel.Loaʻa iā ia nā mea hoʻohuihui e hiki ai ke hoʻohana i loko o ka lua a me ka crevice corrosion environment.Hōʻike ia i ka pale ʻana i ka oxidation i hoʻohālikelike ʻia i nā māka maʻamau.Loaʻa nā waiwai kino i makemake ʻia mai ke kaʻina hana wela.ʻO ka mea maʻamau, ʻo ka alloy 347, ʻaʻole ia he magnetik ma ke ʻano i hoʻopili ʻia, akā naʻe, lilo iki ia i ka magnetic ke ʻike ʻia i nā hana hana anu.
Hoʻokumu i nā kikoʻī
Loaʻa iā ia ka nui o ka paʻakikī hana anu.ʻO ka wela wela o ka huila he 2100-2250 degere F a ua ʻōlelo ʻia no ka hana ʻana.Hoʻopiʻi koke ʻia a hoʻopaʻa ʻia paha e mālama i nā waiwai mechanical kiʻekiʻe.He maikai weldability, machinability, formability, a fabricability hiʻona.
Nānā huahana
I ka manawa o ka hana ʻana, nui ka manawa o nā huahana hewa i hana ʻia.No ka wehe ʻana iā lākou, nānā ʻia lākou ma kā mākou hale hoʻāʻo.ʻO nā hoʻāʻo i hoʻolalelale ʻia e mākou he mau ho'āʻo kūpaʻa kaila kūlohelohe, hoʻāʻo PMI, hoʻāʻo paʻakikī, hoʻokolohua Thermal performance, a me ka hoʻāʻo kemika.ʻO nā hoʻāʻo ʻē aʻe he hoʻokolohua mechanical, hoʻāʻo luku, hoʻāʻo macro, hoʻāʻo IGC, hoʻāʻo corrosion pitting, hoʻāʻo hoʻoemi, hoʻāʻo leakage, a me ka hoʻāʻo ultrasonic.
