ALLOY 600, UNSN06600

ALLOY 600, UNSN06600

Aloyi 600 (UNS N06600)
Chidule Aloyi ya nickel-chromium yokhala ndi kukana kwa okosijeni wabwino pa kutentha kwambiri komanso kukana kusweka kwa chloride-ion stress-corrosion, dzimbiri ndi madzi oyera kwambiri, komanso dzimbiri la caustic. Amagwiritsidwa ntchito pazigawo za ng'anjo, popanga mankhwala ndi chakudya, mu engineering ya nyukiliya, komanso poyaka ma elekitirodi.

Microstructure

Aloyi 600 ili ndi mawonekedwe a cubic omwe ali pakati pa nkhope ndipo ndi aloyi yokhazikika, austenitic solid-solution alloy.
Makhalidwe

Kukana kwa dzimbiri kwabwino kwa media pakuchepetsa, makutidwe ndi okosijeni ndi nitridation;

Chitetezo chokwanira ku chloride-ion stress-corrosion cracking ngakhale pa kutentha kwakukulu;

Kukana kwabwino kwambiri ndi kutentha kwapamwamba kwambiri mu drychlorine ndi hydrogen chloride.
Kukaniza kwa Corrosion

Mapangidwe a Alloy 600 amamuthandiza kukana zowononga zosiyanasiyana. Zomwe zili mu chromium zomwe zili mu alloy zimapangitsa kuti zikhale zapamwamba kuposa faifi tambala yoyera pansi pa oxidizing, ndipo kuchuluka kwake kwa nickel kumathandizira kuti ikhalebe yolimba pakuchepetsa. Zinthu za nickel zimaperekanso kukana kwabwino kwa mayankho amchere.

The aloyi ali ndi kukana chilungamo kwambiri oxidizing asidi njira. Komabe, oxidizing zotsatira za kusungunuka mpweya wokha sikokwanira kutsimikizira passivity wathunthu ndi kumasuka ku kuukira ndi mpweya-saturated mchere zidulo ndi zina moyikira organic zidulo.
Mapulogalamu

1. Chubu cha jenereta chamadzi opanikizidwa ndi madzi;

2. Osinthanitsa kutentha kwa sodium hydroxide;

3. Chigawo chomwe chimagwiritsidwa ntchito popanga zithunzi ndi kukonza mafilimu;

4. Oxychlorinator internals mu kupanga vinyl kolorayidi;

5. Mzere wa zojambulira ndege.
