Nimonic 105(Ni-Cr-Co-Mo)

Post Views: 7

1. Introduce

– Ni-Cr-Co-Mo alloy with age-hardening properties

– Addition of Mo, Al, Ti to improve strength through precipitation hardening

– Excellent 950℃ high temperature strength, heat resistance, and creep resistance

– UNS N13021

* Creep

: The phenomenon in which a material continues to deform over time while a constant load is applied to the material

* Nimonic

* 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 N13021 : 13XXX : Cobalt(with Cr. Mo, W,or precipitation harden)

2. Property

– High temperature strength, heat resistance, and creep resistance

Element	Impact
Ni	Prevents aging hardening, provides good strength and corrosion resistance
Cr	Provides corrosion resistance, oxidation resistance
Co	Provides strength, creep properties
Ti	Provides high temperature strength
Al	Provides high temperature strength, high temperature creep properties
Mo	Provides high temperature creep properties
