Taganizirani izi: Mumazembera mphete yonyezimira yachitsulo chosapanga dzimbiri ndipo mukudzitamandira kwa anzanu kuti, “Taonani chitsulo chosachita dzimbiri!” Patapita mphindi zisanu—"O! Chala changa chikuwoneka ngati Mini-Jurassic Park!" Ndiye… ndi ngwazi ya dermatology yachitsulo chosapanga dzimbiri kapena adani ake akulu? Tiyeni tilowe mkati ndi lilime-m'masaya ndikuwona ngati aloyi yonyezimirayi ili ndi chinsinsi cha "kuyabwa". ndolo zachitsulo zosapanga dzimbiri_副本

Chifukwa Chiyani Zitsulo Zimapangitsa Khungu Lanu Kukhala Lopanduka?

Ingoganizirani chitetezo chanu cha mthupi ngati chowombera pagulu la VIP. Nthawi yomwe ma nickel ions amayesa kuwononga phwando, imakuwa, "Osati pa wotchi yanga!" Onani kuphulika kwa chipwirikiti chofiyira, choyabwa chomwe chikuyenera kumaliza nyengo ya sopo. Nickel ndi mndandanda wa A-list allergen mu dziko lazitsulo-mkuntho chabe wa ayoni ake, ndipo khungu lanu limapanga zionetsero.

Kumanani ndi Banja la Stainless-Steel Family

Chitsulo chosapanga dzimbiri kwenikweni ndi Avengers of zitsulo: chitsulo, chromium, faifi tambala—ndi ma sidekick ochepa—ogwirizana kuti apange mphamvu zolimbana ndi dzimbiri. Koma malingana ndi kuchuluka kwa nickel paulendo wanu, khungu lanu likhoza kugwedeza moyimirira kapena kugwedeza pansi. Tikumane ndi omwe akupikisana nawo:
1. 1. Mtundu wa 304
  - Imani pamzere: ~ 18-20% chromium + 8-10.5% nickel
  - Mphamvu Zapamwamba: Stellar dzimbiri kukana ndi formability
  - Kryptonite: Peresenti ya faifiyi imatha kutuluka thukuta ndikuyambitsa kuwukira kofiira pa dzanja lanu.
2. Mtengo wa 316L (msuweni wocheperako, wofatsa kwambiri)
  - Imani pamzere: ~16–18% chromium + 10–14% nickel + 2–3% molybdenum
  - Mphamvu Zapamwamba: Molybdenum imatseka kutulutsidwa kwa nickel ngati Fort Knox - ngakhale utsi wam'madzi sungathe kuyimitsa
  - Mkhalidwe wa Ngwazi: Kutamandidwa m'malo opangira opaleshoni komanso m'malo oboola thupi - khungu lomvera nickel limapangitsa kuti anthu azisangalala

Kodi Pali “Sewero la Zero-Sewero” la Chitsulo Chopanda banga?

Tikhale enieni—palibe chitsulo chosapanga dzimbiri chomwe chilibe nickel 100%. Koma ngati mukufuna kuletsa kuyabwa, nayi pepala lanu lachinyengo:

Ditch 304, Kukumbatira 316L
Ngati khungu lanu likuyaka mwachangu kuposa kandulo mumphepo, dumphani phwando la 304 ndi RSVP kupita ku 316L soirée.
Gwirizanani ndi Chophimba
PVD kapena rhodium plating ili ngati zida za tuxedo za zodzikongoletsera zanu—maoni a nickel sakhala ndi mwayi.
Perekani Khungu Lanu "Me-Time"
Ngakhale zitsulo zotsekemera zimafuna kusweka. Sinthani zodzikongoletsera zanu, makamaka mukamatuluka thukuta kapena kusambira, ndipo khungu lanu lipume.

316L vs. 316: Kusiyana kwake ndi chiyani?

316L ndi 316 zitsulo zosapanga dzimbiri ndizofanana kwambiri ndi mankhwala - onse ndi aloyi austenitic okhala ndi chromium, nickel, ndi molybdenum. Kusiyana kwakukulu ndi zinthu za carbon:

Mpweya: 316L ili ndi ≤0.03% carbon, pamene 316 ikhoza kukhala ndi 0.08%. Mpweya wochepa uwu umachepetsa kwambiri mwayi wopanga chromium carbide panthawi yowotcherera.
Weldability: 316L kuchepa kwa carbide kumatanthawuza kuti palibe kukhudzidwa pambuyo pa kuwotcherera, kotero madera owotcherera amakhalabe osachita dzimbiri. Mosiyana ndi izi, welded 316 imatha kukhala "kuwola kwa weld" popanda chithandizo choyenera cha kutentha.
Kulimbana ndi Corrosion: Zitsulo zonse ziwiri zimakana dzimbiri bwino, koma 316L ndi yapamwamba kwambiri m'malo a chloride komanso pambuyo pakuwotcherera. Welded 316 amakonda dzimbiri m'madera omwe amakhudzidwa ndi kutentha.
Mphamvu: Chifukwa cha kaboni wowonjezera, 316 nthawi zina imakhala ndi mphamvu zochulukirapo / zokolola kuposa 316L. Pochita kusiyana uku ndi kochepa. M'magwiritsidwe ambiri (kuphatikiza zopangira zolemetsa ndi zomangira), mphamvu za 316L ndizokwanira.
Kagwiritsidwe Ntchito Kanthawi: Nthawi zambiri, 316L imasankhidwa m'madzi, mankhwala, ndi mankhwala ntchito pamene pazipita dzimbiri kukana ndi weldability chofunika. Standard 316 imagwiritsidwa ntchito nthawi zambiri mafakitale, kukonza chakudya, ndi zomangamanga wamba komwe kuwotcherera sikumakhala kocheperako kapena kuwononga kwambiri sizomwe zimayambitsa.

Malangizo a Shrewd Shopper

Chandamale 316L (makamaka mtundu wochepa wa carbon): Khulupirirani maopaleshoni omwewo omwe amagwiritsa ntchito - ngati kuli kokwanira kwa OR, ndikwabwino kwa khutu lanu.

Jambulani zilembo za "Hypoallergenic": Yang'anani "nickel-safe" kapena "dermatologist tested" ndikumwetulira mozama.

Ganizirani Zodzitetezera: Mukufuna mtendere wowonjezera wamalingaliro? Chotchinga chotchinga chimapangitsa kuti ma ion a nickel akhale okhazikika.

Tembenukirani ndi Kupumula: Samalani zodzikongoletsera zanu ngati mndandanda wamasewera - sakanizani zinthu kuti khungu lanu lisamangolumikizana.

Chomaliza:

Ngakhale kulibe chidwi chofuna chitsulo chosapanga dzimbiri chosindikizidwa bwino ndi faifi tambala, 316L (makamaka mtundu wake wa kaboni wotsika) watsimikizira kuti ndi ngwazi yapakhungu. Pokhala ndi kalozera wanzeru uyu, muyenda panjira ya zodzikongoletsera ngati katswiri: "Kodi imeneyo ndi 316L?" mudzafunsa. "Inde? Palibe kuyabwa!"

Tulukani, owalani bwino, ndipo khungu lanu lipume mosavuta—mawonekedwe achitsulo chosapanga dzimbiri.
