Haynes 188 Bars and Rods are cobalt-based alloys, which possess good high-temperature strength and oxidation resistance. The chemical composition is cobalt (Co) ~39-41%, chromium (Cr) ~21-23%, nickel (Ni) ~20-22%, tungsten (W) ~13-15%, iron (Fe) ≤3%, manganese (Mn) ≤1.25%, silicon (Si) ≤0.35%, carbon (C) 0.05-0.15%, and lanthanum (La) ≤0.02%. They display mechanical characteristics like tensile strength at 960 MPa, yield strength at 450 MPa, and elongation of 50% in annealed state. They present better oxidation resistance up to 1093°C and find suitability for the usage of these bars and rods at high stresses within gas turbines as well as for aerospace parts.

Haynes 188 bars and rods exhibit excellent high-temperature strength and oxidation resistance, maintaining structural integrity up to 2000°F (1093°C), making them ideal for aerospace, turbine, and high-performance engine applications.
To maintain Haynes 188 bars, regularly inspect for corrosion or wear, avoid excessive temperature fluctuations, clean with non-abrasive methods, and store in a dry, cool environment to prevent degradation.
Yes, Haynes 188 rods can be customized in size and length according to specific requirements. Manufacturers can provide tailored solutions based on customer specifications for industrial applications.
Haynes 188 bars and rods are high-performance alloys that are traditionally used in applications demanding excellent strength along with resistance to high-temperature oxidation and corrosion. They are often used in aerospace and industrial gas turbine components, which find very high-performance applications, such as in engine parts, combustion chambers, and turbine blades. They also have applications in heat exchangers, power generation, and chemical processing, where their resistance to thermal cycling and aggressive chemicals is critical. Haynes 188’s superior weldability and strength at elevated temperatures make it suitable for both high-temperature structural and pressure-containing components in demanding industries.
