ʻO nā kila kila he mau kila kila kiʻekiʻe.Loaʻa kēia mau kila i nā pūʻulu ʻehā e pili ana i nā kila martensitic, austenitic, ferritic a me ka ua.Hoʻokumu ʻia kēia mau pūʻulu ma muli o ke ʻano crystalline o nā kila kila.
Loaʻa i nā kila kila ka nui o ka chromium i ka hoʻohālikelike ʻia me nā kila ʻē aʻe a no laila ke kūpaʻa maikaʻi i ka corrosion.Loaʻa ka hapa nui o nā kila kila ma kahi o 10% o ka chromium.
ʻO ke kila kila kila 2205 he kila kuhiliʻole duplex nona ka hoʻolālā e hiki ai i ka hoʻohui ʻana i ka hoʻomaikaʻi ʻana i ke kūʻē ʻana i ka lua, ka ikaika kiʻekiʻe, ke koʻikoʻi koʻikoʻi, ka ʻinoʻino a me ka haki.ʻO ka papa 2205 kila kila ke kū'ē i ka ʻinoʻino sulfide a me nā kaiapuni chloride.
Hāʻawi ka ʻikepili ma lalo nei i kahi hiʻohiʻona o ka pae 2205 kila kila.

Waiwai wela
Hāʻawi ʻia nā waiwai wela o ka pae 2205 stainless steel ma ka papa aʻe.
| Waiwai | Metric | Imperial |
| Hiki ke hoʻonui ʻia ka wela (@20-100°C/68-212°F) | 13.7 µm/m°C | 7.60 µin/in°F |
Nā inoa ʻē aʻe
ʻO nā mea like me ke kila kila kila 2205:
- ASTM A182 Papa F51
- ASTM A240
- ASTM A789
- ASTM A790
- DIN 1.4462
Hana a me ka wela
Hoʻopili
Hoʻopili ʻia ke kila kila kila 2205 ma 1020-1070°C (1868-1958°F) a laila kinai ʻia ka wai.
Hana Wela
Hoʻohana wela ka papa 2205 kila kila ma ka pae wela o 954-1149°C (1750-2100°F).Hoʻohana ʻia ka hana wela o kēia ʻano kila kila ma lalo o ka lumi wela i ka wā hiki.
wiliwili
ʻO nā ʻano hana welding i manaʻo ʻia no ka pae 2205 stainless steel me SMAW, MIG, TIG a me nā ʻano electrode uhi lima.I ka wā o ke kaʻina hana hoʻoheheʻe, pono e hoʻomaha ʻia ka mea ma lalo o 149 ° C (300 ° F) ma waena o nā ala a me ka hoʻomehana ʻana o ka ʻāpana weld.Pono e hoʻohana ʻia nā mea hoʻokomo wela haʻahaʻa no ka hoʻoheheʻe ʻana i ke kila kila 2205.
Hoʻokumu
He mea paʻakikī ke hana ʻana i ke kila kila kila 2205 ma muli o kona ikaika kiʻekiʻe a me ka paʻakikī hana.
Mīkini
Hiki ke hoʻohana ʻia ke kila kila kila 2205 me ka carbide a i ʻole nā mea hana kiʻekiʻe.Hoʻemi ʻia ka wikiwiki ma kahi o 20% ke hoʻohana ʻia nā mea hana carbide.
Nā noi
Hoʻohana ʻia ke kila kila kila kila 2205 i nā noi penei:
- Nā kānana kinoea
- Nā pahu kemika
- Nā mea hoʻololi wela
- ʻO nā mea hoʻoheheʻe acetic acid
