Qhov txawv ntawm NIMONIC 75 Bar thiab NIMONIC 80 Bar yog dab tsi?
Qhov txawv ntawm NIMONIC 75 Bar thiab NIMONIC 80 Bar yog dab tsi?
Qhov sib txawv tseem ceeb ntawm NIMONIC 75 tuav thiab NIMONIC 80A (feem ntau hu ua 80) tuav yog tias NIMONIC 80A yog nag lossis daus hardening alloy tsim los txhim kho lub zog thiab nkag siab ntawm qhov kub thiab txias; thaum NIMONIC 75 yog ib qho kev daws teeb meem ntxiv dag zog rau cov alloy uas optimizes formability thiab muab oxidation zoo heev nyob rau nruab nrab mus rau qhov kub thiab txias.
NIMONIC 75 khoom yog dab tsi?
NIMONIC 75 alloy yog 80/20 npib tsib xee-chromium alloy nrog ntxiv titanium thiab carbon. Cov hlau no yog thawj zaug qhia hauv xyoo 1940 rau kev tsim cov turbine hniav. Nws yog ib qho yooj yim rau tshuab thiab weld, thiab muaj zoo corrosion kuj, mechanical zog, thiab kub kuj.
NIMONIC 75 (Alloy 75, 2.4630 / 2.4951):Ib qho 80/20 npib tsib xee-chromium alloy nrog ntxiv titanium thiab carbon. Nws yog lub npe hu rau nws lub siab - kub lub zog, zoo ductility, thiab zoo heev machinability.
NIMONIC 75 Vs NIMONIC 80A Bar
NIMONIC 80A (Alloy 80A, 2.4952):Cov nag lossis daus -nickel hardening-chromium alloy nrog qhov tseem ceeb ntxiv ntawm titanium thiab txhuas, nthuav tawm lub zog tensile zoo heev thiab nkag mus rau hauv qhov kub thiab txias (txog 815 degree).
