Corrosion resistant steel X6NiCrTiMoVB25
2026-08-06 15:01:58 Origin： Remark：0 Click：
X6NiCrTiMoVB25-15-2 superalloy is a heat and corrosion resistant austenitic iron-base material which can be age hardened to a high strength level.
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.
It is also used for low temperature applications requiring a ductile, non-magnetic high strength material at temperatures ranging from above room temperature.
