Ni-Resist 3(Ni-Cr)

Post Views: 3

1. Introduce

– Excellent corrosion resistance in humid steam and corrosive slurry environments

– UNS F41004

* 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

Abbreviation for the Unified Numbering System for Metals and Alloys
Unified unique numbering system for metals and alloys
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
