309 Umuyoboro w'icyuma

Andika 309 ibyuma bitagira umuyonga ni mesh irwanya ubushyuhe ifite akamaro mubushyuhe bugera kuri 1700 ° F. Iyo ubushyuhe bwo hejuru bukenewe busabwa, nikel yo hejuru ya nikel (nukuvuga reba SS310, SS330, Inconel® 600, Incoloy® 800) ikoreshwa mumwanya wubwoko 309 butagira umuyonga. Urebye chromium nyinshi (~ 23%) hamwe na nikel (~ 12%), T-309 ibyuma bitagira umwanda birwanya ruswa cyane, birwanya cyane okiside, bifite ubushyuhe budasanzwe, kandi bitanga imbaraga nziza mubyumba ndetse nubushyuhe bwo hejuru.
Amakuru y'ibicuruzwa
Icyuma Cyuma Icyiciro cya 309 na 309S ni austenitis chromium-nikel ibyuma bitagira umuyonga bikoreshwa kenshi mubushyuhe bwo hejuru. Kubera chromium nyinshi hamwe na nikel, Alloys 309 na 309S irwanya ruswa cyane, irwanya cyane okiside, hamwe nubushyuhe buhebuje mugihe itanga imico myiza mubyumba n'ubushyuhe bwinshi. Itandukaniro riri hagati yicyuma 309 na 309S nibirimo karubone. Alloy 309S ifite imyuka mike ya karubone igabanya imvura ya karbide kandi igateza imbere gusudira. Ibiranga
  • Ubushyuhe ntarengwa bwa 1000 ° C muri serivisi mu kirere
