ʻO ke kila kila kila 317L he ʻano kalapona haʻahaʻa o ke kila kila kila 317.Loaʻa iā ia ka ikaika kiʻekiʻe a me ke kūpaʻa corrosion e like me ke kila 317 akā hiki ke hana i nā welds ikaika ma muli o ka haʻahaʻa o ke kalapona.
Hāʻawi ka ʻikepili ma lalo nei i kahi hiʻohiʻona o ke kila kila kila 317L.
ʻO ke kila kila kila 317L (UNS S31703) hoʻohui kemika
Hoʻohui Kimia
Hōʻike ʻia ka haku mele mele 317L ma ka papa ma lalo nei.
| ʻElemu | Maʻiʻo (%) |
|---|---|
| Hao, Fe | Kaulike |
| Chromium, Cr | 18-20 |
| Nikela, Ni | 11-15 |
| Molybdenum, Mo | 3-4 |
| Manganese, Mn | 2 |
| Silika, Si | 1 |
| Phosphorous, P | 0.045 |
| Kalapona, C | 0.03 |
| Sulfur, S | 0.03 |
Na Waiwai Mechanical
ʻO ke kila kila kila 317L (UNS S31703) hoʻohui kemika
Hōʻike ʻia nā waiwai mechanical o ka pae 317L stainless steel ma ka papa aʻe.
| Waiwai | Metric | Imperial |
|---|---|---|
| Ka ikaika tensile | 595 MPa | 86300 psi |
| Hua ikaika | 260 MPa | 37700 psi |
| Modulus o ka elasticity | 200 GPa | 29000 ksi |
| Lakiō o Poisson | 0.27-0.30 | 0.27-0.30 |
| Elongation ma ka haʻihaʻi (i loko o 50 mm) | 55% | 55% |
| ʻO Hardness, Rockwell B | 85 | 85 |
Nā inoa ʻē aʻe
ʻO ke kila kila kila 317L (UNS S31703) hoʻohui kemika
Hāʻawi ʻia nā mea like me ka pae 317L stainless steel ma lalo nei.
| AISI 317L | ASTM A167 | ASTM A182 | ASTM A213 | ASTM A240 |
| ASTM A249 | ASTM A312 | ASTM A774 | ASTM A778 | ASTM A813 |
| ASTM A814 | DIN 1.4438 | QQ S763 | ASME SA240 | SAE 30317L |
Pono ka hana ʻana i ke kila kila kila 317L i nā māmā haʻahaʻa a me nā hānai mau e hōʻemi i kona makemake e hana paʻakikī.ʻOi aku ka paʻakikī o kēia kila ma mua o ke kila kila kila 304 me kahi puʻupuʻu kaula lōʻihi;akā naʻe, ʻōlelo ʻia ka hoʻohana ʻana i nā mea wāwahi chip.Hiki ke hana ʻia ka welding me ka hoʻohana ʻana i ka hapa nui o ka fusion maʻamau a me nā ala kū'ē.Pono e ʻalo ʻia ke kuʻi ʻana o Oxyacetylene.Manaʻo ʻia ʻo AWS E/ER 317L filler metal.
Hiki ke hana i nā hana hana wela maʻamau.Pono e hoʻomehanaʻia ka mea i 1149-1260 ° C (2100-2300 ° F);akā naʻe, ʻaʻole pono e wela ma lalo o 927°C (1700°F).No ka hoʻonui ʻana i ka pale ʻana i ka corrosion, ʻōlelo ʻia kahi annealing ma hope o ka hana.
Hiki ke ʻako ʻia, ke kaha ʻana, ke poʻo a me ke kaha kiʻi ʻana me ke kila kila kila 317L, a ʻōlelo ʻia ka hoʻopili ʻana ma hope o ka hana e hoʻopau i nā koʻikoʻi o loko.Hana ʻia ka Annealing ma 1010-1121°C (1850-2050°F), pono e ukali ʻia me ka hoʻolili wikiwiki.
ʻAʻole pane ka papa 317L kila kila i ka mālama wela.
Nā noi
Hoʻohana nui ʻia ke kila kila kila 317L i nā noi penei:
- Condensers i loko o ka mōʻalihaku
- Ka hana ʻana i ka pulp a me ka pepa
- Nā kahua hoʻoheheʻe mana i hoʻohana ʻia i ka nuklea
- Nā lako hana kemika a me ka petrochemical.
