GH3039 Alloy Bar

GH3039 yog ib hom austenite cov khoom siv-zog wrought hlau-nickel puag alloy. Cov hlau no yog tsim los ntawm 19% -22% Chromium, Tsawg dua lossis sib npaug ntawm 3.0 hlau, 2.3% molybdenum, sib npaug npib tsib xee, thiab lwm yam khoom. Cov tshuaj lom neeg muaj pes tsawg leeg tso cai rau cov hlau no tuaj yeem pom oxidation tsis kam mus rau qis dua 1000 degree, nruab nrab thermal zog, thiab cov yam ntxwv zoo thermal qaug zog.

Khoom Taw qhia

hwv 3039yog ib-theem austenite-hom khoom tov ntxiv dag zog rau alloys, qis dua 800 degree nrog nruab nrab thermal zog thiab zoo thermal qaug zog zog, 1000 degree hauv qab no zoo oxidation kuj. Kev siv lub sij hawm ntev ntawm cov ntaub so ntswg stability, tab sis kuj muaj qhov txias formability thiab vuam kev ua tau zoo. Haum rau kev siv mus sij hawm ntev ntawm 850 degree hauv qab ntawm aero-engine combustion chamber thiab afterburner qhov chaw. Lub alloy tuaj yeem tsim cov ntawv, tuav, xaim, kav thiab forgings.

Cov txheej txheem kev ua tau zoo:

1. Cov hlau no muaj cov yas zoo kub ua haujlwm thiab kev ua haujlwm zoo deformation. Lub forging cua sov yog 1170 degree, thiab qhov kawg forging kub yog 900 degree.

2. Qhov nruab nrab grain loj ntawm no alloy yog ze ze rau lub degree ntawm deformation ntawm forging thiab qhov kawg forging kub.

3. Alloys tuaj yeem welded siv argon arc vuam, qhov chaw vuam, los yog txoj kev vuam seam, nrog kev vuam zoo heev thiab tsis tshua muaj siab rau cov kab nrib pleb hauv argon arc vuam.

4. Tom qab kev kho cua sov, cov tawv nqaij oxide ntawm cov khoom tuaj yeem raug tshem tawm los ntawm cov xuab zeb tshuab lossis cov kua qaub ntxuav.
