ʻO kaʻO ASTM A312 UNS S30815 253MA Paipu Kinohi PilikinoʻO ke kila kila austenitic kiʻekiʻe i ʻike ʻia no kona kūpaʻa kiʻekiʻe i ka oxidation wela kiʻekiʻe, ka ʻino, a me nā waiwai mechanical maikaʻi loa i nā wahi wela kiʻekiʻe.253MAua hoʻolālā kūikawā ʻia no ka lawelawe ʻana i nā noi e koi ana i ke kūpaʻa wela kiʻekiʻe, ʻoi aku hoʻi i ka umu a me nā ʻoihana mālama wela. ʻO kona kūpaʻa kūʻokoʻa i ka scaling, carburization, a me ka oxidation maʻamau e lilo ia i mea hilinaʻi no nā kaiapuni koʻikoʻi.
Hoʻohana nui ʻia kēia ʻano o ke kila kila i nā noi ʻoihana kiʻekiʻe a he kūpono ia no nā noi kahi i koʻikoʻi ai ka ikaika kiʻekiʻe a me ke kūpaʻa oxidation.
Nā Kūlana a me nā kiko'ī
ʻO kaʻO ASTM A312 UNS S30815 253MA Paipu Kinohi Pilikinohana ʻia e like me nā kūlana aʻe:
- ASTM A312: Hōʻike maʻamau no nā paipu hao hao ʻole ʻole, welded, a me ke anuanu.
- UNS S30815: ʻO ka Unified Numbering System for Materials e hōʻike ana i kēia ma ke ʻano he kila kila kila kiʻekiʻe.
- EN 10088-2: European Standard for Stainless Steel, e uhi ana i na koi no ka haku ana o keia mea, na waiwai mechanical, a me ka hoao ana.
Hoʻohui Kimia(% ma ke kaumaha)
ʻO ka hui kemika o253MA (UNS S30815)ua hoʻolālā ʻia e hāʻawi i ke kūpaʻa maikaʻi loa i ka oxidation a me ka ikaika wela kiʻekiʻe. ʻO ka haku mele maʻamau penei:
| ʻElemu | Huina (%) |
| Chromium (Cr) | 20.00 - 23.00% |
| Nikela (Ni) | 24.00 - 26.00% |
| Silika (Si) | 1.50 - 2.50% |
| Manganese (Mn) | 1.00 - 2.00% |
| Kalapona (C) | ≤ 0.08% |
| ʻOka (P) | ≤ 0.045% |
| Sulfur (S) | ≤ 0.030% |
| Nitrogen (N) | 0.10 - 0.30% |
| Hao (Fe) | Kaulike |
Mea Pono: Nā ʻano nui
253MA(UNS S30815) hoʻohui maikaʻi maikaʻi-kiʻekiʻe-mehana ikaika me ka oxidation kū'ē. He mea kūpono kēia no nā noi i nā kaiapuni koʻikoʻi, e like me nā kapuahi a me nā mea hoʻololi wela. He kiʻekiʻe ka chromium a me ka nickel ka mea, e hāʻawi ana i ke kū'ē maikaʻi loa i ka oxidation ma nā mahana a hiki i 1150 ° C (2100 ° F).

ʻO ka hana ʻana o253MA mau paipu kila kilahahai i nā ʻenehana hana hou e hōʻoia i ka kiʻekiʻe a me ka lōʻihi:
- Hana ʻia ʻo Pipe Seamless: Hana ʻia ma o ka extrusion, rotary piercing, a me nā kaʻina hana elongation e hana i nā paipu seamless me ka mānoanoa pā like ʻole.
- Kaʻina Hana anu: Hoʻohana ʻia nā kaʻina hana kiʻi anuanu a i ʻole ka hele ʻana no ka loaʻa ʻana o nā ana kūpono a me nā ʻili laulima.
- Hoʻomaʻamaʻa Wela: Hoʻomaʻamaʻa ʻia nā paipu ma nā wela kikoʻī e hoʻomaikaʻi i ko lākou mau ʻano mechanical a me ka hana wela kiʻekiʻe.
- Pickling & Passivation: Hoʻopili ʻia nā paipu e hoʻoneʻe i nā kiʻi ʻoniʻoni a me ka oxide a hoʻopaʻa ʻia e hōʻoia i ke kūʻē ʻana i ka corrosion.
ʻO ka hoʻāʻo a me ka nānā ʻana: hōʻoia maikaʻi
Ke hahai nei ʻo Womic Steel i kahi protocol hoʻāʻo koʻikoʻi e hōʻoia i ka maikaʻi kiʻekiʻe loa no253MA mau paipu kila kila:
- ʻIkepili Kimia: Hoʻopaʻa ʻia me ka hoʻohana ʻana i nā ʻenehana spectroscopic e hōʻoia i ka hui ʻana o ka huila i nā haku mele.
