X22CrMoV12-1 cov khoom sib npaug yog dab tsi?
X22CrMoV12-1 (cov ntaub ntawv naj npawb 1.4923) yog martensitic creep-resisting stainless hlau feem ntau siv rau chav turbine hniav, rotors, thiab kub kub bolts txog 600℃. Cov qauv sib npaug suav nrog AISI 422 (USA), Z21CDV12 (Fabkis), thiab zoo sib xws DIN 1.4922 / X20CrMoV12-1.
X22crmov12-1 QT1 khoom yog dab tsi?
X22CrMoV12-1 (1.4923) +QT1 yog martensitic creep-cov hlau tiv taus tsim tshwj xeeb rau siab-kev siv kub txog li 600℃. Nyob rau hauv nws quenched thiab tempered (+ QT1) mob, nws yog haum rau kev tsim khoom ntawm high-pressure Cheebtsam; Ua tsaug rau nws lub zog tensile zoo heev thiab creep rupture lub zog, nws yog nquag siv nyob rau hauv zus tau tej cov chav turbine hniav, fasteners, thiab chav piping Cheebtsam.
