ʻO ke kila kila kila papa 3CR12 kahi papa haʻahaʻa ke kumukūʻai o ke kila kila chromium i hana ʻia ma ka hoʻololi ʻana i nā waiwai o ke kila papa 409. Kūʻē ia i ka pala iki a me ka ʻaʻahu pulu. Ua hoʻomohala mua ʻia e Columbus Stainless Company ma lalo o ka hōʻailona kālepa i hoʻopaʻa inoa ʻia ʻo "3CR12". ʻO nā inoa ʻē aʻe no kēia papa ʻo UNS S40977/S41003 a me 1.4003.
ʻO nā inoa ʻē aʻe e like me nā māka 3CR12 e komo pū ana me nā māka ASME SA240, nā māka ASTM A240/A240M, a me EN 10088.2. Eia nō naʻe, uhi pū ʻo EN 10028.7 i ka papa 1.4003, ʻo ia hoʻi ke kila kila no nā kumu kaomi.
E hāʻawi nā ʻāpana ma lalo nei i nā waiwai koʻikoʻi o ke koʻi kila kila kila 3CR12, ka pepa a me ka pā e like me Euronorm S41003, S40977, ASTM A240/A240M a me EN 10088.2 1.4003.
He mau hoʻohālikelike wale nō nā mea i luna. Ua manaʻo ʻia kēia papa e hāʻawi i kahi hoʻohālikelike o nā mea like me ka hana, a ʻaʻole kū kānāwai nā kikoʻī. Hiki ke hōʻoia ʻia nā kikoʻī kumu inā pono nā mea like pololei.
Hiki ke hoʻohana ʻia ke kila kila papa 3CR12 i nā hana kahi e hāʻawi ai ke kila alumini, galvanized a i ʻole ke kila kalapona i nā hopena maikaʻi ʻole ma muli o kona kūpaʻa ʻana i nā waikawa ikaika a me nā kumu, a me ka haki ʻana i hoʻokumu ʻia e ka palaho koʻikoʻi chloride. Eia naʻe, ʻaʻole e like me ka Papa 304, ʻo ka Papa 3CR12 ka mea haʻahaʻa loa i ke kūpaʻa ʻana i ka crevice a me ka pitting corrosion i ke alo o nā chlorides.
Ma lalo o nā kūlana ambient, ua hoʻomaikaʻi ka papa 3CR12 i ka hoʻomanawanui i ka wai a me nā chlorides, ʻoiai ua hōʻemi ʻia ka corrosiveness o ka chloride content e nā nitrate a me nā sulfate ions. ʻO kekahi o nā hemahema nui o ka papa 3CR12 ʻo ia ka ʻili o ka mea i ka wā e hōʻike ʻia ai i kekahi ʻano kaiapuni. No kēia kumu i kaupalena ʻia ai ka mea i nā noi hoʻonaninani.
Hōʻike ke kila kila kila 3CR12 i ke kūpaʻa haumia ma waena o 600 a me 750°C i ke alo o ka ea a ma waena o 450 a me 600°C i kahi ʻano kaomi. Lilo ka mea i palupalu me ka hoʻolōʻihi ʻana i nā mahana ma waena o 450 a me 550°C. Eia naʻe, ʻaʻole e nalowale ke kūpaʻa o ka mea i ka hopena i kēia pae mahana.
Hoʻomehana ʻia ke kila kila papa 3CR12 ma 700 a 750°C, māhele ʻia i 25mm mau ʻāpana, hoʻomoʻa ʻia kēlā me kēia ʻāpana no 1.5 mau hola. A laila e hoʻomaʻalili i ka mea. Pono e mālama pono e pale aku i ka paʻakikī ʻana i ka wā o ka mālama wela. Hoʻopilikia ʻia nā waiwai mechanical a me ke kūpaʻa ʻana i ka pala o kēia papa e ka mālama ʻana i ka quenching.
Hiki ke hoʻopili ʻia nā ʻano hana kuʻihao i hoʻohana ʻia no nā kila kila austenitic i nā kila kila papa 3CR12. E noʻonoʻo i nā ʻenehana hoʻokomo wela haʻahaʻa e like me GMAW (MIG) a me GTAW (TIG). I ka kuʻihao ʻana, makemake ʻia ka uea hoʻopihapiha papa 309 i hōʻoia mua ʻia i AS 1554.6. Eia nō naʻe, hoʻohana ʻia nā papa 308L, 316L, 309Mo a me 309L o ka uea i nā hihia he nui. Hiki ke wehe ʻia kekahi discoloration i loko o ka huahana soldered me ka hoʻohana ʻana i ke kinoea kākoʻo a i ʻole nā ​​​​ʻano hana e like me ka hoʻomaʻemaʻe a me ka pickling.
ʻO ka hiki ke hana ʻia o ke kila kila kila 3CR12 ma kahi o 60% o ke kila palupalu. ʻOi aku ka haʻahaʻa o kā lākou wikiwiki paʻakikī ma mua o nā kila austenitic, no laila ʻaʻohe pono o nā ʻano hana hana kūikawā.
Loaʻa nā pepa kila kila papa 3CR12 i kahi hoʻopau Hot Rolled Annealed and Pickled (HRAP) maʻamau, a loaʻa nā wili i kahi hoʻopau 2B a i ʻole 2D. Hiki ke hana ʻia nā ʻano ʻeleʻele mai ka mea i ʻōwili wela ʻia, e waiho ana i kahi ʻili ʻeleʻele i hoʻopau ʻia ma ke kila. Loaʻa i ka hoʻopau ʻeleʻele papa 3CR12 ke kūpaʻa maikaʻi i ka pala a me ka haʻalulu haʻahaʻa, no laila kūpono ia no nā noi ʻaʻahu like ʻole.
Aloha kakahiaka Richard, hauʻoli wau e hāʻawi iā ʻoe i kekahi nui o 3Cr12. Hāʻawi mākou i nā mea ma lalo o ka hōʻailona Cromgard C12. E ʻoluʻolu e kelepona mai iaʻu ma 719-597-2423. Jane Robinson.

Ma ka Advanced Materials i Iune 2022, ua kamaʻilio ʻo AZoM me Ben Melrose o International Syalons e pili ana i ka mākeke mea holomua, ka ʻoihana 4.0, a me ka hoʻoikaika ʻana i ka ʻupena zero.
Ma Advanced Materials, ua kamaʻilio ʻo AZoM me Vig Sherrill o General Graphene e pili ana i ka wā e hiki mai ana o graphene a pehea e hōʻemi ai kā lākou ʻenehana hana hou i nā kumukūʻai e wehe i kahi honua hou o nā noi i ka wā e hiki mai ana.
Ma kēia hālāwai ninaninau, kamaʻilio ʻo AZoM me ka Pelekikena o Levicron ʻo Kauka Ralf Dupont e pili ana i ka hiki o ka spindle motika (U)ASD-H25 hou no ka ʻoihana semiconductor.
E ʻike i ka OTT Parsivel², kahi mika neʻe laser hiki ke hoʻohana ʻia e ana i nā ʻano ua āpau. Hiki iā ia ke hōʻiliʻili i ka ʻikepili ma ka nui a me ka wikiwiki o nā ʻāpana e hāʻule ana.
