304 / 304L Umuyoboro w'icyuma

ASTM A312 ASTM A269 ASME SA 213 / ASTM A213 TP304, EN 10216-5 1.4301 ibyuma bitagira umuyonga ni itandukaniro rya chromium 18% - 8% nikel austeniticstainless ibyuma, ibyuma bizwi cyane kandi bikoreshwa cyane mumuryango wibyuma bitagira umwanda.Icyuma kitagira umwanda gifatwa nkuburyo butandukanye bwo gukoresha muburyo bwiza bwo kurwanya ruswa, koroshya guhimba, guhinduka neza, nimbaraga nyinshi hamwe nuburemere buke.
304 Ibyuma bitagira umuyonga nicyuma gisanzwe "18/8";ni byinshi kandi bikoreshwa cyane mubyuma bidafite ingese, biboneka muburyo bwagutse bwibicuruzwa, imiterere kandi birangira kurusha ibindi.Ifite uburyo bwiza bwo gukora no gusudira.Imiterere iringaniye ya austenitis yo mu cyiciro cya 304 ituma ishobora gushushanywa cyane nta guhuza hagati, ibyo bikaba byaratumye iki cyiciro cyiganje mu gukora ibyuma bishushanyije bidafite ingese nka sink, hollow-ware na sasipani.Kuri iyi porogaramu birasanzwe gukoresha ibintu byihariye “304DDQ” (Ubushushanyo bwimbitse).
Icyiciro cya 304 byoroshye feri cyangwa umuzingo byakozwe mubice bitandukanye byo gukoreshwa mubikorwa byinganda, ubwubatsi, nubwikorezi.Icyiciro cya 304 nacyo gifite ubuhanga bwo gusudira.Annealing ya nyuma yo gusudira ntabwo isabwa mugihe cyo gusudira ibice bito.
Icyiciro cya 304L, verisiyo ya karubone yo hasi ya 304, ntisaba annealing nyuma ya weld bityo rero ikoreshwa cyane mubice biremereye (hejuru ya 6mm).Icyiciro cya 304H hamwe nibirimo byinshi bya karubone isanga ikoreshwa mubushyuhe bwo hejuru.Imiterere ya austenitis nayo itanga aya manota gukomera cyane, ndetse no kuri cryogenictemperature.
