Hauv kev lag luam muaj kev pheej hmoo siab - xws li aerospace, nuclear fais fab, thiab kev sib sib zog nqus- cov roj hauv hiav txwv, qhov kev sib tw loj rau cov engineers yog siab - lub voj voog qaug zog tsis ua haujlwm. Feem ntau, cov neeg ua txhaum cai tsis yog cov ntsiab lus tseem ceeb (nickel, chromium, niobium), tab sis tsis muaj kev tswj xyuas cov kab tsis huv xws li phosphorus (P), sulfur (S), thiab lead (Pb).
Txawm hais tias nyob rau hauv GB lossis ASTM cov qauv, "kev lag luam qib" GH4169 tuaj yeem muaj cov kab ke uas tuaj yeem txav mus rau cov ciam teb hauv qab kev ntxhov siab, ua rau cov qoob loo embrittlement.
Ntawm Gnee Steel, peb tshem tawm qhov kev pheej hmoo no los ntawm kev tswj hwm purity zoo dua. Peb nkag siab tias rau lub cav turbine discs los yog siab -siab fasteners, tshuaj muaj pes tsawg leeg yog qhov tseem ceeb rau kev ncaj ncees ntawm cov qauv.

Cov ntsiab lus tshuaj muaj pes tsawg leeg ntawm GH4169 Nickel Alloy
GH4169 yog nag lossis daus-nickel hardening{2}}chromium- hlau-raws li superalloy (sib npaug rau Inconel 718) tsim los rau siab zog, qaug zog, thiab corrosion kuj ntawm qhov kub txog li 650℃. Nws cov khoom tseem ceeb suav nrog kwv yees li 50-55% npib tsib xee, 17-21% chromium, kwv yees li 5% niobium thiab tantalum, thiab ib qho tseem ceeb ntawm cov hlau, thiab nws yog tsim rau aerospace thiab nuclear kev siv.
Puas yog Inconel 718 yog npib tsib xee-raws li superalloy?
Inconel 718 yog npib tsib xee-raws li superalloy, zoo tagnrho rau cov ntawv thov uas xav tau lub zog siab kom tswj tau qhov kub thiab txias ntawm qhov kub qis mus rau 1400℃F (760℃).

FAQ
Q1: Vim li cas Boron (B) ntxiv rau hauv qhov nqaim (0.003-0.006%)?
A: Boron yog "ob- ntaj ntug." Hauv kev tswj hwm, nws ntxiv dag zog rau cov ciam teb, txhim kho creep- tawg lub neej. Boron ntau dhau, txawm li cas los xij, ua rau muaj teeb meem vuam. Peb cov txheej txheem VIM ua kom Boron khaws cia rau hauv "Golden Range" rau kev ua haujlwm zoo.
Q2: Tsawg Sulfur (S) cuam tshuam cov khoom siv li cas?
A: Tsawg Sulfur (tsawg dua lossis sib npaug li 0.005%) yog qhov tseem ceeb rau kev ua haujlwm kub thiab kev ncaj ncees ntawm qhov chaw. Nws tiv thaiv kev tsim ntawm qis- melting-point sulfides uas tuaj yeem ua rau "Kub Shortness" thaum lub sij hawm forging los yog vuam.
Q3: Puas yog koj GH4169 sib npaug rau Nimonic 90 lossis Inconel 718?
A: GH4169 yog qhov sib npaug ncaj qha ntawmInconel 718 (UNS N07718) Cov.. Nws yog qhov sib txawv metallurgical system dua li Nimonic 90.
Q4: Koj puas muab ntawv pov thawj rau cov ntawv thov cryogenic?
A: Yog. GH4169 yog qhov zoo heev rau kev pabcuam ua kua hydrogen. Peb tuaj yeem muab cov kev ntsuas cuam tshuam ntxiv ntawm Charpy ntawm -196℃txhawm rau txheeb xyuas cov khoom siv tawv rau cov haujlwm cryogenic.
