Nimonic 75(Ni-Cr)

Post Views: 7

1. Introduce

– 80/20 Ni-Cr alloy with Ti and C additions

– High temperature low creep and heat resistance, excellent oxidation resistance
→ Forms an oxide film on the surface to prevent oxidation and deterioration of the material

– UNS N06075

* Nimonic

Ni-Cr alloy
Excellent heat and oxidation resistance
Alloy of Ni and Cr with trace amounts of Ti and Al

* UNS

Abbreviation for Unified Numbering Systems for Metals and Alloys
Unified unique numbering system for metals and alloys
A representative number that is compatible with metals and alloys defined in many material-related codes such as ASTM, AISI, ASME, AWS, etc.

* N : Nickel and nickel alloys

* UNS N06075 : 06XXX : Chromium (Precipitation-hardenable alloy)
