Olwan Nickel Alloys, based in Amman, Jordan, is a trusted manufacturer and supplier of high-quality Incoloy washers designed for demanding industrial environments. These washers are engineered to provide exceptional corrosion resistance, heat resistance, and durability, ensuring secure and long-lasting fastening in critical applications. Produced with precision and adhering to strict quality standards, Olwan Nickel Alloys delivers washers that meet international specifications. Industries such as chemical processing, petrochemical, power generation, and marine engineering rely on these washers to maintain structural integrity and performance of equipment exposed to harsh chemicals, high temperatures, and extreme operating conditions.
Incoloy washers are primarily composed of nickel, iron, and chromium, with added molybdenum and copper for enhanced corrosion resistance and mechanical strength. This alloy offers excellent protection against oxidizing and reducing agents, as well as resistance to pitting, crevice, and stress corrosion cracking. The washers maintain high tensile strength, toughness, and dimensional stability even under elevated temperatures and harsh chemical environments. Their excellent mechanical and metallurgical properties make them suitable for critical fastening applications, ensuring long-term reliability and performance in industrial operations where strength and corrosion resistance are essential.
