Ni-Resist 2(Ni-Cr)


1. Introduce

– Higher Ni content than Ni-Resist 1 for better corrosion resistance in alkaline environments

– UNS F41002

* Ni-Resist

– “Ni-Resist” : means that the base remains austenitic due to the high content of Ni (typically more than 20% Ni)

– High-Ni alloys with Ni content of 13 to 37%, providing good corrosion resistance to alkaline fluids and media containing dilute acids and chlorides

– Ni Heat Resistant Corrosion Resistant Cast Iron

– Excellent oxidation resistance to temperatures up to 925°C

* UNS

    1. Abbreviation for the Unified Numbering System for Metals and Alloys
    2. Unified unique numbering system for metals and alloys
    3. A representative number compatible with metals and alloys defined in several material-related codes, including ASTM, AISI, ASME, AWS, etc.

    * F : Cast irons and Cast steels

    2. Property

    – Ductility, high temperature strength, low coefficient of thermal expansion, thermal shock resistance, corrosion resistance, oxidation resistance
