GH3030 round bars (tseem hu ua NiCr20Ti, XH78T, los yog 2.4806) yog npib tsib xee -chromium raws li cov khoom siv ntxiv dag zog rau superalloy tuav nrog zoo heev - kub cov khoom, tsim tshwj xeeb rau kev siv nyob rau hauv oxidizing ib puag ncig mus txog 800℃-1100 degree. Round bars ua los ntawm cov alloy no tshwj xeeb tshaj yog haum rau siab - qhov kub thiab txias structural Cheebtsam.
GH3030 khoom yog dab tsi?
GH3030 yog lub siab -kub npib tsib xee-raws li superalloy feem ntau siv rau hauv cov khoom uas yuav tsum tau muaj kev tiv thaiv oxidation siab thiab thermal stability. Vim nws ua tau zoo heev nyob rau hauv siab - ib puag ncig kub, GH3030 yog dav siv nyob rau hauv aerospace thiab fais fab kev lag luam.

FAQ
Q1: Vim li cas Titanium (Ti) tseem ceeb hauv GH3030?
A:Hauv ntau qhov siab -temp alloys, cov nplej loj tuaj yeem tswj tsis tau ntawm 800 degree, ua rau cov hlau tsis muaj zog. CovTi ntxiv hauv GH3030ua raws li cov nplej refiner. Nws tsim cov carbonitrides ruaj khov uas "tus pin" cov ciam teb ntawm cov qoob loo, ua kom cov qauv zoo thiab ductile.
