Nā Waiwai Kemika

ʻO ka papa kila kila 304 he kila kila austenitic i haku ʻia me 18% chromium (Cr) a me 8% nickel (Ni), e hāʻawi ana i ke kūpaʻa maikaʻi loa i ka pala, ka hiki ke hoʻokumu ʻia, a me ka hiki ke hoʻopili ʻia. ʻO kāna ʻano kemika maʻamau:

ʻElemene Hoʻonohonoho ʻana (%)

Chromium (Cr) 18.0 – 20.0

Nikala (Ni) 8.0 – 10.5

Kalapona (C) ≤0.08

Manganese (Mn) ≤2.0

Silika (Si) ≤1.0

ʻO ka phosphorus (P) ≤0.045

Sulfur (S) ≤0.03

Hao (Fe) Kaulike

Nā noi

Ma muli o kona kūpaʻa a me ke kū'ē'ē'ana i ka oxidation, ho'ohana nui'ia ka papa kila kila 304 i:

 ʻOihana Meaʻai a me Mea Inu (nā pahu hana, nā kāʻei hoʻoili)

 Nā Lako Kemika a me nā Lapaʻau (nā pahu mālama, nā reactors)

 Kuhikuhipuʻuone a me ke kūkulu ʻana (nā panela elevator, cladding)

 Nā Lako Lapaʻau a me nā Lako Keʻena Hoʻokolohua (nā pā sterilization, nā mea hana ʻoki kino)

 Nā kaʻa a me nā mokulele (nā ʻāpana kūkulu, nā ʻōnaehana hoʻopau)

 Nā lako hale a me nā lako kuke (nā papa hana, nā poho holoi)

 Nā kikoʻī

Loaʻa nā papa kila kila 304 i nā nui like ʻole, nā mānoanoa, a me nā hoʻopau ʻili:

 Pae Mānoanoa: 0.1mm a 100mm (mānoanoa ʻoihana maʻamau: 0.5mm - 50mm)

 Ka laulā: 1000mm, 1219mm, 1500mm (maʻamau), a i ʻole nā ​​​​nui maʻamau

 Lōʻihi: 2000mm, 2438mm, 3000mm, a i ʻole nā ​​lōʻihi maʻamau

 Nā Hoʻopau ʻIli:

 2B: Laumania, ʻālohilohi iki (ʻo ka mea maʻamau)

 BA (Bright Annealed): ʻIke nui ʻia, e like me ke aniani

 Helu 4 (Palaki ʻia): Hoʻopau matte me nā laina palaoa i ʻike ʻia

 Helu 8 (Akaʻaka): Hoʻopili ʻia i kahi ʻōlinolino kiʻekiʻe

 Nā Kūlana Maʻamau:

ASTM A240 (Kuhikuhi maʻamau no ka papa kila kila chromium a me chromium-nickel)

 EN 1.4301 (like ʻEulopa me 304)

 JIS SUS304 (kūlana Kepanī)

 GB/T 3280 (maʻamau Kina)

 Makemake nui ʻia ka papa kila kila 304 no kona kūpono i ke kumukūʻai, ke kūpaʻa i ka pala, a me ka maʻalahi i nā noi ʻoihana a me nā ʻoihana.
