Pāpā kila kila

E like me ke ʻano hana, ʻelua ʻano o ka ʻōwili wela a me ka ʻōwili anu, me ka 0.5-4 mm mānoanoa pepa a me 4.5-35 mm mānoanoa pā.

E like me nā hiʻohiʻona o ke kila, hiki ke hoʻokaʻawale ʻia i ʻelima mau ʻano: austenite, austenitic-ferrite, ferrite, martensite a me ka paʻakikī paʻakikī.

E hoʻohana i ke kaiapuni: lawe i ka corrosion o ka oxalic acid, sulfate-ferric sulfate, nitric acid, nitric acid-hydrofluoric acid, sulfate-copper sulfate, phosphoric acid, formic acid, acetic acid a me nā mea ʻē aʻe.

Hoʻohana: hoʻohana ʻia i ka kemika, ka meaʻai, ka lāʻau lapaʻau, ka pepa, ka aila, ka ikehu atomic a me nā ʻoihana ʻē aʻe, a me nā ʻāpana like ʻole a me nā ʻāpana o nā hale, nā lako kīhini, nā papa ʻaina, nā kaʻa a me nā mea pono hale.I mea e hōʻoia ai i ka hoʻokō ʻana o ka ikaika hua, ka ikaika tensile, ka elongation, ka paʻakikī a me nā ʻano mechanical ʻē aʻe o nā papa kila stainless i nā koi, pono nā papa kila e hana i ka annealing, ka hoʻonā hopena, ka mālama ʻana i ka wā kahiko a me nā lāʻau wela ʻē aʻe ma mua o ka lawe ʻana.

ʻO nā koi maikaʻi: ʻo ka pā kila kila he ʻili maʻemaʻe, ka plasticity kiʻekiʻe, ka paʻakikī a me ka ikaika mechanical, a kūpaʻa i ka corrosion o ka waika, alkaline gas, solution a me nā media ʻē aʻe.He kila kila ʻaʻole maʻalahi i ka ʻōpala, akā ʻaʻole ia he ʻeleʻele loa.ʻO ke kūpaʻa ʻino o ke kila kila ma muli o kāna ʻano huila (chromium, nickel, titanium, silicon, aluminika, etc.) a me ka hale o loko.ʻO ka hana nui he chromium.Loaʻa i ka Chromium ke kūpaʻa kemika kiʻekiʻe, hiki ke hana i kahi kiʻiʻoniʻoni passivation ma ka ʻili kila, hoʻokaʻawale i ka metala mai waho, pale i ka pā kila mai ka oxidation, a hoʻonui i ke kūpaʻa corrosion o ka pā kila.Ma hope o ka luku ʻia ʻana o ka kiʻiʻoniʻoni passivation, e hoʻemi ke kūpaʻa corrosion.
