Mea waiwai

1.4112 (S46990, S44003, sus440b, X90CrMoV18)

haku mele

C: 0.85～0.95%; Si: ≤1.0%; Mn: ≤1.0%; P: ≤0.04%; S: ≤0.015%; Cr: 17～19%; Mo: 0.9～1.3%; V: 0.07～0.12 %; Fe: kaulike

waiwai waiwai

Māmā: 7.7g/cm³; ikaika tensile: 590MPa; ikaika hua: 245MPa; elongation: 15%; paakiki HBW: 269; ke kinai a me ka paʻakikī paʻakikī: 55HRC.

Hana mīkini

1.4112 he kila kila martensitic kiʻekiʻe. ʻO kona mau mea mechanical ka nui o ka ikaika, ka paʻakikī, ka paʻakikī, a me nā mea'ē aʻe. I ka manawa like, ma muli o kona paʻakikī maikaʻi, ʻaʻole maʻalahi kēia ʻano kila i ka embrittle a hiki ke hoʻohana ʻia i nā wahi paʻakikī. Kūleʻa i ka ʻino mai ka lewa mālie, ka mahu wai hou, ka amonia, ka nui o nā huahana petroleum a me nā mea kūlohelohe, a me nā ʻano kaiapuni palupalu nāwaliwali. He haʻahaʻa loa ka mahana annealing, a he kiʻekiʻe ka paʻakikī ma hope o ke kinai ʻana. Hiki i ka paʻakikī ke hiki i ka HRC56-58. Loaʻa iā ia ka pale corrosion maikaʻi (magnetic) a me ka paʻakikī ikaika.

Nā wahi noi

No ka mea he 1.4112 stainless steel ka maikaʻi o ka corrosion resistance a me ka mechanical properties, ua hoʻohana nui ʻia ia i ka ʻaila, ʻoihana kemika, ʻenekinia moana, nā kaʻa, nā meaʻai a me nā māla ʻē aʻe. I ka ʻoihana ʻaila a me nā kemika, ma muli o kona kūpaʻa maikaʻi ʻana i ka corrosion, hoʻohana ʻia ia e hana i nā reactors, pipelines a me nā mea hana ʻē aʻe. Ma ke kahua o ka ʻenekinia moana, hoʻohana ʻia ia e hana i nā ʻāpana koʻikoʻi o nā moku a me nā kahua o waho. Ma ke kahua kaʻa, hoʻohana ʻia ia e hana i nā ʻāpana e like me nā ʻōnaehana exhaust a me nā mea paʻa. Ma ke kahua meaʻai, hoʻohana ʻia ia e hana i nā lako kīhini a me nā mea hana meaʻai ma muli o kāna mau waiwai maʻemaʻe maikaʻi.

Hana hana

ʻO nā waiwai kaʻina hana o 1.4112 stainless steel ka nui o ka welding, ka mālama wela a me ka hoʻoili waiwai. ʻO kēia ʻano kila he hana wili maikaʻi a hiki ke hoʻohana ʻia me ka hoʻohana ʻana i nā ʻano hana wili. Hiki i ka mālama wela ke hoʻomaikaʻi i kona mau waiwai mechanical a me ka pale ʻana i ka corrosion, akā pono e mālama i ka pale ʻana i ka haki ʻana a i ʻole ka deformation ma muli o ka wela a i ʻole overcooling. Loaʻa iā ia ka hana hoʻoponopono maikaʻi a hiki ke hoʻohana ʻia no ka huli ʻana, wili, wili, paʻi a me nā hana hana ʻē aʻe. ʻO kona mau pōʻino ʻo ia ka paʻa a me ka wela wikiwiki, akā ʻoi aku ka maʻalahi o ke one ma mua o nā kila kalapona a ʻoi aku ka maʻalahi o ka ʻoki ʻana me ka ʻike lima.

Nā koi hoʻoponopono ʻāpana
