Hastelloy Hexagon Rods
Our rods are widely used in chemical processing equipment, reactors, heat exchangers, valves, marine and offshore components, aerospace parts, and high-performance fabrication applications. Industries across India, including Tamil Nadu’s industrial corridors, Andhra Pradesh’s chemical plants, Karnataka’s aerospace facilities, and Telangana’s power generation units, rely on Rose Metal Industries for high-quality Hastelloy products. Even in coastal regions such as Puducherry and the Andaman & Nicobar Islands, where corrosive environments are prevalent, our Hastelloy rods provide long-lasting performance..
Mechanically, Hastelloy Hexagon Rods demonstrate high tensile strength, excellent yield strength, and superior elongation, ensuring durability under stress. Typical tensile strength ranges from 550–750 MPa, while yield strength lies between 200–380 MPa depending on the alloy and heat treatment. These properties, combined with hardness values of HRB 90–95, make the rods suitable for heavy-duty industrial applications requiring both structural integrity and corrosion resistance..
The chemical composition of Hastelloy Hexagon Rods is carefully controlled to provide exceptional resistance to oxidizing and reducing agents. Key elements include nickel, molybdenum, chromium, iron, and cobalt, which together form a highly stable alloy capable of withstanding highly corrosive environments, including acids, chlorides, and marine atmospheres. This makes our rods ideal for critical applications where both strength and chemical resistance are paramount.
