2. Dab tsi yog cov kev siv ntau ntawm cov nickel alloy kav thiab cov kav dej?
Teb: Cov kav dej no yog siv rau hauv kev lag luam uas xav tau kev tiv thaiv corrosion thiab siab - qhov kub thiab txias:
Cov nroj tsuag tshuaj thiab petrochemical
Marine thiab offshore engineering
Cov khoom siv hluav taws xob tsim hluav taws xob (boilers, heat exchangers)
Aerospace Cheebtsam
Nuclear kev lag luam
3. Cov khoom siv dab tsi tuaj yeem xav tau los ntawm cov hlau no?
Teb: Tej yam khoom (tej zaum yuav txawv los ntawm kev kho cua sov):
Inconel 718: Tensile zog 124 ksi (855 MPa), yield zog 103 ksi (710 MPa), elongation 12-20%.
C276: Tensile zog 80-120 ksi, yield zog 35-75 ksi, elongation 30-40%.
Inconel 800H: Tensile zog 70 ksi (480 MPa), yield zog 30 ksi (205 MPa), elongation 40%.
4. Cov kav dej no ua raws li cov qauv thiab cov ntawv pov thawj dab tsi?
Teb: Lawv feem ntau ntsib:
ASTM B564 (Inconel 718) / ASTM B622 (C276) / ASTM B409 (800H)
ASME B31.3 rau cov kav dej siab
ISO 9001 ntawv pov thawj kev tsim khoom
Material Test Certificate (MTC) raws li EN 10204 3.1
5. Yuav ua li cas yog corrosion kuj ntawm cov nickel alloys?
Teb:
Inconel 718: Kev tiv thaiv zoo heev rau oxidation thiab siab -kub corrosion, zoo rau nruab nrab aggressive tshuaj ib puag ncig.
C276: Zoo heev tiv thaiv kom muaj zog oxidizing thiab txo cov neeg ua haujlwm, suav nrog hydrochloric thiab sulfuric acids.
Inconel 800H: Zoo tiv taus siab -kub oxidation thiab carburization; haum rau cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob.
