Zvimiro zveMakemikoro

Purati yesimbi isina ngura ye304 isimbi isina ngura inogadzirwa ne18% chromium (Cr) uye 8% nickel (Ni), inopa simba rakanaka rekudzivirira ngura, kuumbwa, uye kuchinjika. Makemikoro ayo anowanzo sanganisira:

Chinhu Kuumbwa (%)

Chromium (Cr) 18.0 – 20.0

Nickel (Ni) 8.0 – 10.5

Kabhoni (C) ≤0.08

Manganese (Mn) ≤2.0

Silikoni (Si) ≤1.0

Phosphorus (P) ≤0.045

Sarufa (S) ≤0.03

Simbi (Fe) Kuenzana

Mashandisirwo

Nekuda kwekugara kwayo kwenguva refu uye kuramba kwayo kuoxidation, 304 stainless steel plate inoshandiswa zvakanyanya mu:

 Indasitiri yezvekudya nezvinonwiwa (matangi ekugadzirisa, mabhandi ekutakura zvinhu)

 Midziyo yemakemikari nemishonga (matangi ekuchengetera, ma reactors)

 Magadzirirwo ezvivakwa & Kuvaka (mapaneru erifti, machira emadziro)

 Midziyo yekurapa neyemurabhoritari (matireyi ekuuraya utachiona, zvishandiso zvekuvhiya)

 Mota & Ndege (zvikamu zvemuumbirwo, masisitimu eutsi)

 Midziyo yemumba neyekicheni (makaunda, masinki)

 Magadzirirwo

Maplate esimbi asina ngura 304 anowanikwa muhukuru hwakasiyana-siyana, ukobvu, uye kupedzisa pamusoro:

 Hukobvu: 0.1mm kusvika 100mm (hukobvu hwemaindasitiri hwakajairika: 0.5mm - 50mm)

 Upamhi: 1000mm, 1219mm, 1500mm (yakajairwa), kana saizi dzakagadzirwa

 Kureba: 2000mm, 2438mm, 3000mm, kana urefu hwakagadzirwa

 Kupera Kwepamusoro:

 2B: Yakapfava, inopenya zvishoma (inonyanya kuoneka)

 BA (Bright Annealed): Inonyatsoratidza, yakaita segirazi

 Nhamba 4 (Yakakweshwa): Kupedzisa kusina kusimba nemitsara yetsanga inooneka

 Nhamba 8 (Girazi): Rakakweshwa kusvika rapenya zvakanyanya

 Mitemo Yakafanana:

ASTM A240 (Zviratidzo zvakajairwa zve chromium uye chromium-nickel simbi isina tsvina)

 EN 1.4301 (yakaenzana ne304 muEurope)

 JIS SUS304 (muyero wechiJapan)

 GB/T 3280 (muyero wechiChinese)

 Purati yesimbi isingatsvi 304 inonyanya kufarirwa nekuda kwekushanda kwayo zvakanaka, kuramba ngura, uye kushandiswa kwayo kwakasiyana-siyana mumaindasitiri nemabhizinesi.
