Nerjaveèi asye fabrikasyon
Nerjaveèi asye fabrikasyon se pwosesis la nan koupe ak koube metal la nan yon fòm vle, ak soude souvan obligatwa ansanm ak fabwikasyon fè yon pwodwi fini asye pur. Netwayaj, detartraj, marinated ak pasivasyon yo mande apre pwosesis fabrikasyon an, ak tretman sa a pral jenere yon fim pasif sou sifas la asye ki pral bay pwoteksyon korozyon.
| Ki sa ki asye pur? |
Stainless steel is an alloy of iron with a minimum of 10.5 percent chromium which automatically and instantaneously react with oxygen to form a chromium-rich oxide film, and this film will naturally self-passivate and maintain the corrosion resisting passive surface condition. Due to this character, stainless steel has self-repairing corrosion protection capability. Nerjaveèi dwe gen pa mwens pase 10.5 pousan nan kontni CHROMIUM ak maksimòm 1.2 pousan kabòn dapre EN10088-1. Nerjaveèi asye a nòmalman gen lòt eleman alyaj tankou nikèl, molybdène, nitwojèn ak Titàn pou amelyore kapasite rezistans korozyon, epi li anpil ogmante karaktè mekanik li yo ki kouvri fòmabilite, fòs ak rezistans chalè.
| Avantaj nan asye pur |
√ Resikle
√ Netwaye Sifas
√ Segondè fòs
√ Ki pa-mayetik
√ Durability nan yon pri ki ba
√ Segondè korozyon reziste
√ Segondè rezistans korozyon
√ Segondè Low -Rezistans Tanperati
√ Fasil yo dwe fabrike an tèm de koube ak D
√ Pifò klas nan fanmi austenitic yo soude, men degre nan efikasite depann sou klas la.
| Erè komen pandan fabrikasyon asye pur |
√ Surface damage, defects and contamination during fabrication are potentially harmful to the oxide film that protects stainless steel .
√ Scratches and mechanical damage, this kind of damage causes crevices on the steel surface which provides ideal kote pou reyaktif oswa kontaminan.
√ Dust and grime arising during fabrication
√ Oil, grease, fingerprints, crayon and paint marks may also cause crevices for corrosion.
√ Residual adhesives from tape which will cause crevice corrosion.
√ Fabrication process mixed with carbon steel, and loose iron particles which rapidly rust and initiate corrosion.
√ Previously used steel wire brushes or grinding tool for carbon steel is now used for stainless steel fabrication.
√ Spatter, slag and stray arc strikes are potential sites for crevice corrosion.
√ Welding cracks due to contaminated material and incomplete penetration.
√ Heat tint and scale

| How to Make Fabricated Pati asye pur Have Honger Lifespan? |
Actually, the lifespan of a fabricated stainless-steel parts is decided by two factors, application condition and surface treatment after the fabrication. Here let's take a close look at the surface treatment process, and this is vital for delivering high quality products to our clients.
1. Netwayaj, retire grès oswa lwil oliv dwe toujou anvan lave asid, ak rezidyèl nan lwil oliv oswa kontaminan inòganik pa ka anpeche kouch pasif fòme byen.
2. Detartraj, retire echèl oksid vizib ki anjeneral gri fonse
3. Pickling, remove unwanted metal by mixture of nitric and hydrofluoric acids, it's quite a common solution for remove weld heat tinted layers. There are few different way of pickling.
3.1 Tank immersion marinated
3.2 Flite marinated
3.3 Sikilasyon marinated
Li enpòtan pou travayè a konplètman okouran de klas espesifik nan asye ke yo te marinated ak korozyon ka rive si tan kontak asid pa byen kontwole.
4. Rense, rezidyèl nan marinated ak kontaminasyon yo dwe konplètman rense pou reyalize yon sifas ki konplètman rezistan tach korozyon.
5. Pasivasyon, asid nitrique lajman itilize pou fòme fim nan kwòm -rich oksid pasif,ak pwosesis sa a retire kontaminan ak pèmèt pou yon fim pasif yo dwe fòme sou yon sifas ki fre.
| Aplikasyon nan fabrikasyon asye pur |
Nerjaveèi yo itilize nan yon varyete aplikasyon ki enplike segondè fyab estriktirèl ak rezistans. Anplis de sa ke yo fasil pou netwaye epi kenbe ijyenik, yo souvan chwazi asye pur paske li reziste domaj chalè epi li fasil pou kenbe, asire lonjevite machin li itilize pous. Lè l sèvi avèk ekipman avanse nou an, Fabmann ka bay divès kalite kouvèti solisyon fabwikasyon. koupe lazè, pwensonaj, fòme metal, woule, ak soude, kidonk nou ka toujou rekòmande solisyon an fabwikasyon optimize pou ou. Fabrikasyon koutim nou an apwopriye pou endistri sa yo:
Fabmann itilize sitou 304 ak 316 materyèl asye pur pou pwodui pati koutim tankou parantèz, estrikti ak pwofil pou endistri manje ak machin akòz avantaj materyèl nan prèv korozyon -. Ansyen an, melanje ak 18 pousan chromium ak 8 pousan nikèl, yo chwazi pou durability li yo, ansanm ak gwo rezistans li nan tou de korozyon ak oksidasyon. Pou lèt la, melanje ak 16 pousan chromium, 10 pousan nikèl ak 2 pousan molybdène, se pi plis rezistan chalè ak rezistans korozyon souvan itilize nan endistri gaz lwil oliv kòm yon rezilta.
Enjenyè pwodiksyon nou an gen anpil konesans sou fason pou evite erè komen ki gen rapò ak fabwikasyon asye pur, ak ekip pwodiksyon nou an ap fè pi byen yo pou evite ak minimize potansyèl korozyon ki asosye ak pwosesis fabrikasyon an.
