Premium Haynes 188 Bars and Rods, made for use in extremely hot and corrosive conditions, are manufactured and supplied by Dhruv Metals, a reputable company based in Hyderabad, India. Haynes 188 alloy products are designed to satisfy crucial needs in industrial processing, power generation, and aerospace and are renowned for their exceptional mechanical strength, oxidation resistance, and thermal stability. These bars and rods are available from Dhruv Metals in a range of sizes and specifications to meet the needs of the client. Dhruv Metals is known for providing high-performance materials for the most demanding applications because of its dedication to accuracy, quality control, and prompt delivery.
Cobalt (39–41%), nickel (20–24%), chromium (21–24%), and tungsten (13–15%) make up Haynes 188 Bars and Rods, with trace amounts of carbon and lanthanum. This high-performance alloy offers superior strength in extremely hot conditions and outstanding oxidation resistance up to 1095°C. It provides good elongation (20–30%), yield strength (400–550 MPa), and tensile strength (850–1000 MPa). Haynes 188 is appropriate for prolonged exposure to harsh, high-temperature environments, especially in thermal processing and aerospace systems, because it retains structural integrity under thermal fatigue and stress.

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.
In high-temperature applications where resistance to oxidation, creep, and thermal fatigue is essential, Haynes 188 Bars and Rods are frequently utilised. They are utilised in turbine engine parts, transition ducts, afterburner parts, and combustion liners in the aerospace sector. They are perfect for parts of industrial furnaces and gas turbines that are subjected to constant thermal cycling in the power generation industry. Equipment used in heat treatment and petrochemical processes that need to operate dependably at high temperatures can also benefit from the alloy. Haynes 188 is a material of choice for demanding engineering solutions in harsh service environments because of its remarkable strength and metallurgical stability.
