ASTM A312 UNS S30815 253MA Urupapuro rwubuhanga rwa tekinoroji

Intangiriro

UwitekaASTM A312 UNS S30815 253MA Umuyoboro wibyumani imikorere-yimikorere ya austenitike idafite ibyuma bizwiho kurwanya imbaraga zo kurwanya ubushyuhe bwo hejuru, kwangirika, hamwe nubukanishi buhebuje mubushyuhe bwo hejuru.253MAyateguwe byumwihariko kuri serivisi mubisabwa bisaba ubushyuhe bwo hejuru cyane cyane mu ziko n’inganda zitunganya ubushyuhe. Kurwanya kwinshi kwinshi, kwangiza, hamwe na okiside rusange bituma iba ibikoresho byizewe kubidukikije bikabije.

Uru rwego rwibyuma bitagira umwanda bikoreshwa cyane mubikorwa byubushyuhe bwo hejuru kandi nibyiza kubisabwa aho imbaraga nyinshi hamwe na okiside irwanya imbaraga.

Ibigize imiti(% kuburemere)

Ibigize imiti ya253MA (UNS S30815)yashizweho kugirango itange imbaraga nziza zo kurwanya okiside hamwe nubushyuhe bwo hejuru. Ibigize bisanzwe ni ibi bikurikira:

Ikintu

Ibigize (%)
Chromium (Cr) 20.00 - 23.00%
Nickel (Ni) 24.00 - 26.00%
Silicon (Si) 1.50 - 2,50%
Manganese (Mn) 1.00 - 2.00%
Carbone (C) ≤ 0.08%
Fosifore (P) ≤ 0.045%
Amazi (S) ≤ 0.030%
Azote (N) 0.10 - 0,30%
Icyuma (Fe) Kuringaniza

Ibintu Byiza: Ibiranga Ibyingenzi

253MA(UNS S30815) ikomatanya imbaraga nziza zubushyuhe bwo hejuru hamwe no kurwanya okiside. Ibi bituma biba byiza mubisabwa mubidukikije bikabije, nk'itanura no guhanahana ubushyuhe. Ibikoresho bifite chromium nyinshi na nikel, bitanga imbaraga nziza zo kurwanya okiside ku bushyuhe bugera kuri 1150 ° C (2100 ° F).

Ibintu bifatika

  • Ubucucike: 7.8 g / cm³
  • Ingingo yo gushonga: 1390 ° C (2540 ° F)
  • Amashanyarazi: 15.5 W / m · K kuri 100 ° C.
  • Ubushyuhe bwihariye: 0,50 J / g · K kuri 100 ° C.
  • Kurwanya amashanyarazi: 0,73 μΩ · m kuri 20 ° C.
  • Imbaraga: 570 MPa (ntarengwa)
  • Gutanga Imbaraga: 240 MPa (ntarengwa)
  • Kurambura: 40% (byibuze)
  • Gukomera (Rockwell B): HRB 90 (ntarengwa)
  • Modulus ya Elastique: 200 GPa
  • Ikigereranyo cya Poisson: 0.30
  • Kurwanya bihebuje ubushyuhe bwo hejuru bwa okiside, gupima, na karburizasi.
  • Igumana imbaraga kandi ikora ituze ku bushyuhe burenga 1000 ° C (1832 ° F).
  • Kurwanya birenze urugero aside irike na alkaline.
  • Kurwanya sulfure na chloride iterwa no guhangayika.
  • Irashobora kwihanganira ibidukikije bikaze, bigatuma biba byiza gukoreshwa mugutunganya imiti hamwe nubushyuhe bwo hejuru bwinganda.

Inzira yumusaruro: Ubukorikori bwa Precision

Gukora253MA Imiyoboro idafite ibyumagukurikiza uburyo bugezweho bwo gukora kugirango hamenyekane ubuziranenge kandi burambye:

  1. Gukora imiyoboro idahwitse: Yakozwe hifashishijwe gusohora, gutobora kuzunguruka, no kurambura inzira kugirango habeho imiyoboro idafite uburinganire hamwe nubunini bwurukuta rumwe.
  2. Inzira y'ubukonje: Igishushanyo gikonje cyangwa uburyo bwo gutembera bikoreshwa kugirango ugere ku bipimo nyabyo kandi bigaragara neza.
  3. Kuvura Ubushuhe: Imiyoboro ikorerwa ubushyuhe mubushyuhe bwihariye kugirango yongere imiterere yubukorikori hamwe nubushyuhe bwo hejuru.
  4. Gutoranya & Passivation: Imiyoboro iratoragurwa kugirango ikureho ibipimo bya firime na oxyde kandi bigahita byoroha kugirango birusheho kwangirika.

Kwipimisha no Kugenzura: Ubwishingizi Bwiza

Womic Steel ikurikiza protocole igerageza kugirango ireme neza253MA Imiyoboro idafite ibyuma:

  • Isesengura ryibigize imiti: Kugenzurwa ukoresheje tekinoroji ya spekitroscopique kugirango wemeze ko ibivanze byujuje ibihimbano byihariye.
  • Ikizamini cya mashini: Guhangayika, gukomera, no kugerageza ingaruka kugirango ugenzure imikorere yibintu mubushyuhe butandukanye.
  • Ikizamini cya Hydrostatike: Imiyoboro irageragezwa kugirango irambe kugirango ireme neza.
  • Ikizamini kidasenya (NDT): Harimo ultrasonic, eddy iriho, hamwe no gusiga irangi ryinjira kugirango umenye inenge iyo ari yo yose imbere cyangwa hejuru.
  • Kugenzura & Kugereranya: Buri muyoboro urasuzumwa neza kugirango urangire hejuru, kandi uburinganire buringaniye bugenzurwa nibisobanuro.

Kubindi bisobanuro cyangwa amagambo yihariye, hamagara Womic Steel uyumunsi!
