Ua hoʻouna aku mākou i ka pepa kila kila 321 1 * 1220 * 2440 no kā mākou mea kūʻai mai UAE

Nā Waiwai Hemical

ʻO ke kila kila 321 he kila kila austenitic i hoʻopaʻa ʻia e ka titanium (like me 304 akā me ka titanium i hoʻohui ʻia e pale i ka chromium carbide precipitation). Hāʻawi ia i ke kūpaʻa wela kiʻekiʻe a me ke kūpaʻa intergranular corrosion.

ʻO ke ʻano hana kemika maʻamau (%):

ʻElemene Hoʻonohonoho ʻana

Chromium (Cr) 17.0 – 19.0

Nikala (Ni) 9.0 – 12.0

Kalapona (C) ≤0.08

Manganese (Mn) ≤2.0

Silika (Si) ≤1.0

ʻO ka phosphorus (P) ≤0.045

Sulfur (S) ≤0.03

Titanium (Ti) ≥5×C (min. 0.4%)

Hao (Fe) Kaulike

Nā Hiʻohiʻona Koʻikoʻi

✔Paʻa o ka mahana kiʻekiʻe (a hiki i 800-900°C)

✔Kū'ē i ka hoʻopulapula carbide (sensitization) i ka wā o ka hoʻopili ʻana

✔Maikaʻi ke kūpaʻa ʻana i ka oxidation a me ka corrosion (ʻoi aku ka maikaʻi ma mua o 304 ma kekahi mau wahi)

Nā noi

Ma muli o kona kūpaʻa wela a me ka hiki ke hoʻopili ʻia, hoʻohana nui ʻia ke kila kila 321 i:

Nā ʻĀpana Aerospace a me nā ʻenekini mokulele (nā ʻōnaehana hoʻopau, nā keʻena kuni)

Nā Lako Kemika a me Petrochemical (nā mea hoʻololi wela, nā ipu kaomi)

Nā Paipu Wela Kiʻekiʻe a me nā Boilers (paʻa wela)

Nā ʻōnaehana hoʻopau kaʻa (manifolds, catalytic converters)

Nā Lako Hana Meaʻai a me nā Lapaʻau (kahi e pono ai ka hoʻoheheʻe ʻana)

Nā ʻĀpana Lapaʻau Wela a me ka Umu (ma muli o ke kūpaʻa ʻana i ka oxidation)

Nā Kikoʻī a me nā ʻAno

Loaʻa ke kila kila 321 ma:

1. Pā / Pepa

Mānoanoa: 0.1mm–100mm

Laulā: 1000mm, 1219mm, 1500mm (maʻamau)

Nā Hoʻopau ʻIli:

2B (laumania, ʻālohilohi iki)

Helu 4 (palaki ʻia, hoʻopau matte)

BA (ʻālohilohi i hoʻomehana ʻia, e like me ke aniani)

2. Paipu / Tube

ʻAʻohe wili a hoʻopaʻa ʻia

Nā Nui: 1/8″ a 24″ (a i ʻole ke ʻano maʻamau)

Nā Kūlana: ASTM A312, A213

3. Pā / Koʻokoʻo

Poepoe, huinahā, ʻāpana hexagonal

Anawaena: 1mm–500mm

4. Uea a me nā mea hoʻopaʻa

Hoʻohana ʻia i nā ʻōwili wela kiʻekiʻe, nā nati, a me nā pūnāwai

Nā Kūlana Honua

Kūlana Maʻamau Hoʻohanohano like

ASTM A240 (Papa), A312 (Paipu), A276 (ʻAu)

EN (EU) 1.4541 (X6CrNiTi18-10)

JIS (Iapana) SUS321

GB (Kina) 0Cr18Ni10Ti

No ke aha e koho ai i ke kila kila 321?

✅Hana maikaʻi loa i ka mahana kiʻekiʻe (vs. 304/316)

✅Hoʻemi ʻia ka pilikia o ka pala intergranular ma hope o ka hoʻopili ʻana

✅Hoʻohana nui ʻia i nā ʻoihana aerospace, automotive, a me nā kemika
