DUPLEX Stainless STEEL TYPE giredhi UYE STANDARD

•Lean Duplex SS – nickel yakaderera uye isina molybdenum – 2101, 2102, 2202, 2304
•Duplex SS – nickel yepamusoro uye molybdenum – 2205, 2003, 2404
•Super Duplex – 25Chromium uye nickel yepamusoro uye molybdenum “plus” – 2507, 255 uye Z100
•Hyper Duplex – More Cr, Ni, Mo neN – 2707

Mechanical Properties:
•Duplex Stainless Steels dzine simba rakapetwa kaviri regoho reimwe yadzo austenitic mamakisi.
•Izvi zvinobvumira vagadziri vemidziyo kushandisa thinner gauge zvinhu pakuvaka ngarava!

Duplex Stainless simbi mukana:
1. Kuenzaniswa ne austenitic Stainless simbi
1) Simba regoho rinopfuura zvakapetwa kaviri kupfuura yeyakajairika austenitic simbi isina tsvina, uye ine kukwana kwepurasitiki kuoma kunodiwa pakuumbwa.Ukobvu hwetangi kana dhishi ngarava yakagadzirwa ne duplex simbi isina tsvina i30-50% yakaderera pane iyo inowanzo shandiswa austenitic simbi isina tsvina, iyo inobatsira kuderedza mutengo.
2) Iyo ine yakanakisa kupikisa kushushikana nekupwanya kwecorrosion, kunyanya munzvimbo ine chloride ion, kunyangwe iyo duplex alloy ine yakaderera alloy yemukati ine yakanyanya kupikisa kushushikana nekupwanya kwekupwanya pane austenitic simbi isina tsvina.Stress corrosion idambudziko rakakurumbira iro rakajairwa austenitic simbi isina tsvina yakaoma kugadzirisa.
3) Iyo inonyanyozivikanwa 2205 duplex simbi isina tsvina inoshandiswa mune dzakawanda midhiya ine zvirinani kusagadzika pane yakajairwa 316L austenitic simbi isina tsvina, nepo super duplex simbi isina simbi ine yakakwira corrosion resistance.Mune mamwe ma media, akadai seacetic acid uye formic acid.Inogona kutsiva yakakwirira-alloy austenitic simbi isina tsvina uye kunyange corrosion-resistant alloys.
4) Iine kupikisa kwakanaka kune corrosion yemunharaunda.Kuenzaniswa neaustenitic Stainless simbi ine yakafanana alloy content, ine zvirinani kupfeka kuramba uye corrosion kuneta kuramba pane austenitic Stainless simbi.
5) Iyo austenitic simbi isina tsvina ine yakaderera coefficient ye linear kuwedzera uye iri pedyo nekabhoni simbi.Inokodzera kubatanidzwa nekabhoni simbi uye ine yakakosha kukosha kweinjiniya, sekugadzira mahwendefa emubatanidzwa kana linings.

2. Kuenzaniswa neferritic Stainless simbi, zvakanakira duplex Stainless simbi ndezvizvi:
1) Iwo akazara mechanicha zvivakwa akakwira kupfuura ayo eferritic Stainless simbi, kunyanya kuoma kwepurasitiki.Kwete sekunzwa kune brittleness se ferritic Stainless simbi.
2) Pamusoro pekusimbisa corrosion resistance, kumwe kupikisa kwekugara kwekugara kwakakwirira kune ferritic simbi isina tsvina.
3) Cold working process performance uye kutonhora kuumba kuita kuri nani pane ferritic stainless simbi.
4) Iyo welding performance iri nani pane iyo ferritic Stainless simbi.Kazhinji, hapana kurapwa kwekupisa kunodiwa mushure mekutanga kupisa pasina welding.
5) Rudzi rwemashandisirwo rwakakura kupfuura iyo yeferritic Stainless simbi.

ApplicationNekuda kwesimba rakawanda resimbi ye duplex, inoita kuchengetedza zvinhu, sekudzikisa kukora kwemadziro epombi.Kushandiswa kweSAF2205 uye SAF2507W semuenzaniso.SAF2205 inokodzera kushandiswa munzvimbo dzine chlorine uye inokodzera kushandiswa mukunatsa kana imwe nzira midhiya yakasanganiswa nechloride.SAF 2205 inonyanya kukodzera kushandiswa mumagetsi ekupisa ane aqueous chlorine kana brackish mvura semhepo inotonhorera.Izvo zvinhu zvakare zvakakodzerwa nekudzikisa sulfuric acid mhinduro uye yakachena organic acids uye musanganiswa wayo.Zvakadai se: mapaipi emafuta muindasitiri yemafuta uye gasi: kubviswa kwemafuta asina kuchena mune zvekunatsa, kucheneswa kwemagasi ane sulfur, midziyo yekuchenesa mvura;masisitimu ekutonhodza achishandisa mvura ine brackish kana chlorine-containing solutions.
