ERNiCrMo-3 Hlau

 

ERNiCrMo-3 yog npib tsib xee-chromium-molybdenum (Ni-Cr-Mo) alloy vuam cov khoom ua raws li American Welding Society (AWS) A5.14 tus qauv, feem ntau muab los ua cov xaim xaim.

Nws kuj yog dav paub tias yog Inconel 625 vuam cov khoom vim nws cov khoom siv hlau tso rau hauv zoo ib yam li lub qhov dej zoo -paub INCONEL 625 (UNS N06625) alloy. Cov khoom siv no muaj cov ntawv thov tseem ceeb hauv ntau qhov kev lag luam vim nws qhov zoo tshaj plaws corrosion kuj, superior siab - kub lub zog, thiab zoo weldability.

 

 

ERNiCrMo-3 yog ib qho alloy nrog npib tsib xee (Ni) ua lub hauv paus hlau thiab ntxiv cov ntsiab lus xws li chromium (Cr), molybdenum (Mo), thiab niobium (Nb). Cov ntsiab lus tshwj xeeb sib txawv me ntsis thoob plaws ntau qhov chaw, tab sis qhov ntau ntawm cov ntsiab lus tseem ceeb tseem nyob ib puag ncig.

Cov lus hauv qab no qhia txog cov tshuaj muaj pes tsawg leeg:

Element	Kev sib xyaw (%)
Nickel (Ni)	5 8,0mn
Chromium (Cr)	20.0 - 23.0
Molybdenum (hli)	8.0 - 10.0
Niobium (Nb)	3.15 - 4.15
Hlau (Fe)	5.0 max
Manganese (Mn)	0.50 max
Silicon (Si)	0.50 max
Cov pa roj carbon (C)	0.10 max
Phosphorus (P)	0.015 max
Sulfur (S)	0.015 max
Aluminium (Al)	0.40 max
Titanium (Ti)	0.40 max
Cobalt (zeeg)	1.0 max

• Lub cev muaj zog: Qhov ceev yog kwv yees li 8.4 g / cm³, melting point range yog 1290-1350 degree.
• Mechanical Properties: Cov hlau weld feem ntau pom muaj zog thiab zoo ductility. Lub zog tensile feem ntau tsis tsawg dua 760 MPa, thiab elongation tsis tsawg dua 30%. Ib txoj kev tshawb fawb 2024 tau suav cov ciam teb ntxiv dag zog rau kev sib txawv ntawm cov vuam hlau siv Hall-Petch formula, nrog rau qhov muaj nuj nqis ntawm 316.62 txog 356.96 MPa.
• Corrosion Resistance thiab High Temperature Resistance: Cov alloy no nthuav tawm zoo heev corrosion kuj nyob rau hauv ob qho tib si oxidizing thiab txo ib puag ncig, tshwj xeeb tshaj yog tiv taus pitting corrosion, crevice corrosion, thiab kev nyuaj siab corrosion cracking, ua rau nws haum rau hnyav ib puag ncig uas muaj chlorides. Nws qhov kev ua haujlwm siab - qhov kub thiab txias yog qhov ruaj khov, nrog rau qhov dav siv qhov kub thiab txias, los ntawm qis- qhov kub thiab txias ib puag ncig mus rau qhov kub siab ntawm kwv yees li 540℃txog 1000℃F (kwv yees li 538℃).

 

 

ERNiCrMo-3 vuam hlau muaj ntau yam kev siv, feem ntau suav nrog:

• Vuam ntawm cov alloys tshwj xeeb: Tsim tshwj xeeb rau vuam nickel{0}}chromium- molybdenum alloys xws li INCONEL 625, INCONEL 825, INCOLOY 825, thiab Alloy 20.
• Vuam ntawm cov khoom sib txawv: Tsim nyog rau vuam cov khoom sib txawv xws li npib tsib xee-raws li alloys nrog stainless hlau, thiab ultra- siab- lub zog hlau nrog npib tsib xee alloys.
• Npog (cladding): Siv rau overlaying corrosion-resistant nickel-chromium-molybdenum alloy hlau rau ntawm cov hlau.
• Kev lag luam kev lag luam: Siv dav hauv petrochemical, marine engineering, aerospace, nuclear fais fab, hluav taws xob fais fab (xws li cov kav dej thiab cov khoom siv reactor), kev tswj cov pa phem, thiab kev tsim cov tshuab hnyav.

 

 

Cov ntaub ntawv khoom: Cov khoom sib txuas vuam hlau muaj rau ntau yam txheej txheem vuam xws li MIG / GMAW (Gas Shielded Hlau Arc Vuam), TIG / GTAW (Tungsten Inert Gas Vuam), thiab SAW (Submerged Arc Vuam). Cov kab uas muaj xws li 0.8, 1.0, 1.2, 1.6, 2.4, thiab 3.2 mm. Qee cov neeg muag khoom kuj tseem muab cov kab uas hla zoo tshaj plaws xws li 0.025 mm rau cov ntawv tshwj xeeb.

Standards: Feem ntau ua raws li cov qauv AWS A5.14.
