304H Umuyoboro w'icyuma

GUSOBANURIRA

304H nicyuma cya austenitis kitagira ibyuma, gifite chromium 18-19% na nikel 8-11% hamwe na karubone ntarengwa 0.08%. 304H imiyoboro idafite ibyuma ni imiyoboro inyuranye kandi ikoreshwa cyane mumuryango wibyuma. Bagaragaza imbaraga zo kurwanya ruswa, imbaraga zidasanzwe, ubworoherane bwo guhimba, hamwe nuburyo bugaragara. Kubwibyo, bikoreshwa muburyo butandukanye bwurugo nubucuruzi bukoreshwa. 304H ibyuma bidafite ingese bifite karubone igenzurwa ya 0.04 kugeza 0.10. Ibi bitanga imbaraga zubushyuhe bwo hejuru, ndetse hejuru ya 800o F. Ugereranije na 304L, 304H imiyoboro idafite ibyuma ifite imbaraga zigihe gito nigihe kirekire. Na none, barwanya ubukangurambaga kuruta 304L.

304H UMUTUNGO W'INGINGO ZIKURIKIRA

Hano havuzwe hano haribintu byingenzi biranga 304H imiyoboro idafite ibyuma itangwa na Arch City Steel & Alloy:

Kurwanya Ubushyuhe:

  • Birakwiriye kubushyuhe bwo hejuru, kuko butanga imbaraga nyinshi mubushyuhe buri hejuru ya 500 ° C na 800 ° C.

  • Icyiciro cya 304H gitanga imbaraga nziza zo kurwanya okiside muri serivisi zigihe gito kugeza kuri 870 ° C no muri serivisi zihoraho kuri 920 ° C.

  • Ahinduka ubukangurambaga mu bushyuhe bwa 425-860 ° C; kubwibyo ntibisabwa niba amazi arwanya ruswa.

Kurwanya ruswa:

  • Kurwanya ruswa mu bidukikije bya okiside, hamwe na acide kama kama ikabije bitewe na chromium na nikel.

  • Ikora kimwe mubice byinshi byangirika

  • Urashobora kwerekana igipimo cyo kwangirika ugereranije na karubone yo hejuru 304.

Gusudira:

  • Byoroshye gusudira nibikorwa bisanzwe.

  • Birashobora gusabwa gushira nyuma yo gusudira

  • Annealing ifasha mukugarura ruswa yatakaye no gukangurira.

Gutunganya:

  • Basabwe gukora ubushyuhe bwa 1652-2102 ° F.
  • Imiyoboro cyangwa imiyoboro igomba gufatirwa kuri 1900 ° F.
  • Ibikoresho bigomba kuzimya amazi cyangwa gukonjeshwa vuba
  • Icyiciro cya 304H kirahinduka kandi kirahinduka byoroshye
  • Gukonja bifasha kongera imbaraga nubukomezi bwicyiciro 304H
  • Gukonjesha birashobora gutuma amavuta akoreshwa na magnetique

Imashini:

  • Ibisubizo byiza bigerwaho kumuvuduko gahoro, gusiga neza, ibiryo biremereye, hamwe nibikoresho bikarishye

  • Ukurikije akazi gakomeye hamwe no kumena chip mugihe cyo guhindura ibintu.

Gusaba Icyiciro cya 304H Imiyoboro idafite ibyuma

Ingero zimwe za porogaramu urwego 304H rusanzwe rukoreshwa harimo:

  • Uruganda rutunganya peteroli
  • Amashanyarazi
  • Imiyoboro
  • Guhindura ubushyuhe
  • Umuyoboro
  • Imyuka irambuye
  • Iminara ikonje
  • Amashanyarazi
  • Rimwe na rimwe bikoreshwa mu ifumbire no mu bimera
