Designed specifically for extreme high-temperature environments, Haynes 188 is a high-performance superalloy. This material provides a superior solution when ordinary stainless steel cannot meet requirements. Using Haynes 188 ensures the durability of tubos de acero inoxidable y accesorios de tubería de acero inoxidable, providing long-term reliability where it is most needed.
What is Haynes 188: A High-Performance Cobalt-Based Alloy
Haynes 188 (UNS R30188) is a specialised aleación a base de cobalto renowned for its high strength and excellent oxidation resistance. It is composed of cobalt, nickel, chromium and tungsten, giving it outstanding thermal stability.
Key Strengths of Haynes 188
Haynes 188 performs reliably at extreme temperatures and resists deformación por fluencia. It can be used in furnace and engine components.
Its high contenido en cromo provides resistance to degradation in oxidising atmospheres and protection against sulphurisation.
The strength of this material does not decline rapidly at high temperatures like other materials.
Haynes 188 is easy to form and weld. It is suitable for complex manufacturing processes and for creating strong, reliable joints in piping systems.
