Iyi mhuri yemapurisa yakaberekwa kunze kwekuda kuchengetedza nickel
Iro 200 mutsara ikirasi rekusimudzira (kunyanya kusagadzikana-kusinga) mashizha asina tsvina ayo anozivikanwa nekutora nickel zvakagadzikana. Izvi zvinonziwo se chrome-manganese (CrMn) simbi isina chinhu .
Austenitic steels, iyo inosanganisira zvose mazana maviri nemakumi matatu emasero asina zvisikwa, zvinotsanangurwa nevakatarisana nekakomic. Iko ndiko kuti, kiristiki yakarongeka ine atomu imwe pakona imwe neimwe ye cube uye imwe iri pakati pechiso chimwe nechimwe.
Izvi zvinopesana nemiti inonzi ferritic, iyo inoratidzirwa ne-body-centered cubic structure.
Kugadzirwa kwe 200 Series Stainless Steels
Nickel ndiyo inonyanya kushandiswa kuti ibudise chimiro chekristini, asi mushure mekunge-Hondo Yenyika II nickel kushayikwa kwakatungamirira kuisa nzvimbo ye nitrojeni nickel mukugadzirwa kwezvimwe zvipfeko zvisingadziviriri zvinopisa. Mazana mazana maviri emashizha asina mashizha akaberekwa.
Kunyange zvazvo nitrogen yakashandiswa musimbi inogadzirawo maziso ekugadzirisa mashizha, inoita kuti ine nitride inokonzera chromium uye inowedzera gas porosity. Kuwedzerwa kwema manganese kunobvumira mamwe nitrojeni kuti awedzere akachengetedzwa, asi nickel haigoni kubviswa zvachose kubva kune alloy. Iro 200 mhete dzisina zvisikwa zvisina mavara, naizvozvo, dzinoratidzwa ne nitrogen uye manganese.
Kugadzirwa uye kudiwa kwemajasi asina kuvharidzira asina tsvina akaputika muma1980 sezvo nickel mitengo yakasimuka uye zvakare, kuedza kwakaitwa kuderedza kushandiswa kwesimbi.
Izvi zvakakonzera kukura kwekukura kukuru kwekugadzira muIndia. Asiya iye zvino ndiyo inonyanya kukosha, uye mutengi we, iyi mhuri yemapurisa.
Mifananidzo ye 200 Series Stainless Steels
Kunyange zvazvo kurwisa kusina simba, iyo nyaya 200 ine simba rakadzika kupfuura mazana matatu ekudzivirira kurwisana nepitting corrosion, iyo inowanikwa mumamiriro ezvinhu ane hunyoro huzhinji uye chlorine zviri mukati, pamwe chete nehutu hwekuguma, izvo zvinoguma mumvura yakasviba uye yakakwirira ye-acid.
Izvi ndechokuti, kuitira kuti kuderedza nickel yehuwandu, zvigadzirwa zve chromium zvinofanirawo kuderedzwa, nokudaro kuderedza kusagadzikana kwehurosi.
Shanduro 200 dzisina utinha dzakagadzirisa zvakakosha kusagadzikana uye kuoma, kunyange muzasi (kunyange che cryogenic) kutonhorera. Inowanzova yakaoma uye ine simba kudarika mazana matatu ezvinyorwa, zvikurukuru zvichienderana nehuwandu hwavo hwepamusoro we nitrogen, iyo inoita sekusimbisa. Nemhaka yokuti iyo inoshandiswa, zvose mazana maviri nemakumi mana eine mashizha asina tsvina haana magnetic.
Kunyange zvazvo vashandi vekudzivirira vachikwira kudhura kupfuura avo vanobatana nawo, mazana 200 akadhura kuti atange kudhura kupfuura mazana matatu emahofisi nekuda kwezvinyorwa zvadzo zvepasi.
Izvo zvakasanganiswa 200, zvisinei, zvinokonzerwa nekugadzikana kwakadzika ( ductility ) kupfuura 300 series grade, kunyange izvi zvingagadziridzwa nekuwedzera kwemhangura .
Zvinyorwa zve 200 Series Stainless Steels
Pamusana pekudzivirira kwaro kwakadzika, huwandu hwekushandiswa kwemasanganisi mazana maviri easina zvisingasviki hupfupi kupfuura mazana matatu ehupfumi. Hazvikurudzirwi kuti zvishandiswe mumamiriro emakemikari asi yakawana nzira yayo mune zvinhu zvakawanda zveimba.
Mamwe mapurogiramu e200 series inosimbiswa nesimbi isina kusanganisira anosanganisira:
- Dishwashers uye kushambwa kwemichina
- Cutlery uye cookware
- In-house matanki emvura
- Indoor and noncritical architecture panorama
- Zvokudya uye zvinwiwa zvigadzirwa
- Motokari (maitiro)
- Motokari (inoshongedza)
