Austenitic steel 1.4980
2026-07-31 08:51:52 Origin： Remark：0 Click：
1.4980 is an iron-base alloy with content of 26Ni - 15Mo - 2.0Ti, its useful for applications requiring high strength and corrosion resistance, lower stress applications at higher temperatures
DIN 1.4980 (X6NiCrTiMoVB25-15-2) is an iron-base superalloy useful for applications requiring high strength and corrosion resistance up to 700°C and for lower stress applications at higher temperatures.
DIN 1.4980 (X6NiCrTiMoVB25-15-2) superalloy is a heat and corrosion resistant austenitic iron-base material which can be age hardened to a high strength level.
It is also used for low temperature applications requiring a ductile, non-magnetic high strength material at temperatures ranging from above room temperature.
Type 1.4980 is generally produced by EAF + AOD refining or VIM, and vacuum arc VAR or electroslag remelting ESR procedures may be used to further refine the material.
