He mau kila kila kiʻekiʻe nā kila kila. Loaʻa kēia mau kila i ʻehā mau pūʻulu e komo pū ana me nā kila martensitic, austenitic, ferritic a me nā kila precipitation-hardened. Hoʻokumu ʻia kēia mau pūʻulu ma muli o ke ʻano crystalline o nā kila kila.
ʻOi aku ka nui o ka chromium i loko o nā kila kila kila i ka hoʻohālikelike ʻia me nā kila ʻē aʻe a no laila he kūpaʻa maikaʻi ko lākou i ka pala. ʻO ka hapa nui o nā kila kila kila he 10% o ka chromium.
ʻO ke kila kila kila papa 2205 he kila kila kila duplex nona ka hoʻolālā e hiki ai ke hoʻohui i ke kūpaʻa i hoʻomaikaʻi ʻia i ka pitting, ka ikaika kiʻekiʻe, ka pala koʻikoʻi, ka pala crevice a me ka nahā. Kūʻē ke kila kila papa 2205 i ka pala koʻikoʻi sulfide a me nā wahi chloride.
Hāʻawi ka pepa ʻikepili ma lalo nei i kahi ʻike holoʻokoʻa o ke kila kila kila 2205.

Nā Waiwai Wela
Hāʻawi ʻia nā waiwai wela o ke kila kila 2205 ma ka papa ma lalo nei.
| Nā Waiwai | Metrika | ʻEmepela |
| Hoʻonui like ʻana o ka hoʻonui wela (@20-100°C/68-212°F) | 13.7 µm/m°C | 7.60 µin/in°F |
Nā Hoʻohanohano ʻē aʻe
ʻO nā mea like me ke kila kila 2205:
- Papa ASTM A182 F51
- ASTM A240
- ASTM A789
- ASTM A790
- DIN 1.4462
Hana ʻana a me ka mālama wela
Hoʻoheheʻe ʻana
Hoʻomehana ʻia ke kila kila papa 2205 ma 1020-1070°C (1868-1958°F) a laila hoʻopau ʻia me ka wai.
Hana Wela
Hana wela ʻia ke kila kila papa 2205 ma ka pae mahana o 954-1149°C (1750-2100°F). Paipai ʻia ka hana wela ʻana o kēia kila kila papa ma lalo o ka mahana o ka lumi i nā manawa hiki.
Kuʻihao
ʻO nā ʻano hana kuʻi i ʻōlelo ʻia no ke kila kila kila papa 2205 e komo pū me SMAW, MIG, TIG a me nā ʻano hana electrode i uhi ʻia e ka lima. I ka wā o ke kaʻina hana kuʻi, pono e hoʻomaʻalili ʻia ka mea ma lalo o 149°C (300°F) ma waena o nā hele ʻana a pono e pale ʻia ka hoʻomehana mua ʻana o ka ʻāpana kuʻi. Pono e hoʻohana ʻia nā mea hoʻokomo wela haʻahaʻa no ka kuʻi kila kila kila papa 2205.
Ke hoʻokumu nei
He paʻakikī ke hana ʻia ke kila kila papa 2205 ma muli o kona ikaika kiʻekiʻe a me ka wikiwiki o ka paʻakikī ʻana.
Ka hiki ke hana mīkini
Hiki ke hana ʻia ke kila kila papa 2205 me ka carbide a i ʻole ka mea hana wikiwiki. Hoʻemi ʻia ka wikiwiki ma kahi o 20% ke hoʻohana ʻia ka mea hana carbide.
Nā noi
Hoʻohana ʻia ke kila kila papa 2205 i nā noi aʻe:
- Nā kānana kinoea flue
- Nā pahu kemika
- Nā mea hoʻololi wela
- Nā ʻāpana hoʻoheheʻe waikawa acetic
