![Profile Picture](https://www.123articleonline.com/images/avatar-default.jpg)
Haynes 188™ is a cobalt-based alloy known for its exceptional high-temperature strength and oxidation resistance up to 2000°F (1095°C). This alloy is also recognized for its good resistance to sulfidation and excellent metallurgical stability, which contributes to its ease of fabrication. These properties make Haynes 188™ highly suitable for demanding applications, particularly in the aerospace and gas turbine engine industries.
Key Characteristics:
High-Temperature Strength: Maintains excellent mechanical properties at elevated temperatures.
Oxidation Resistance: Effective up to 2000°F, providing durability in high-temperature oxidizing environments.
Sulfidation Resistance: Offers good resistance to damage from sulfur-containing environments.
Metallurgical Stability: Ensures that the alloy remains stable under high-temperature conditions, facilitating easy fabrication.
