High Nickel Alloy Square Rods
Applications: These high-performance alloy rods are widely used in chemical processing, aerospace, marine engineering, oil & gas, power generation, and other industrial sectors requiring superior corrosion resistance and high-temperature stability. They are also employed in manufacturing pumps, valves, heat exchangers, turbine components, and other critical machinery.
Dimensions and Equivalent Grades: Square rods are supplied in standard sizes and can be customized to meet client requirements. Common dimensions range from 6×6 mm to 200×200 mm, with lengths between 1000 mm and 3000 mm. Equivalent grades include ASTM B160/B161 (Nickel), UNS N02200/N02201, and other international standards for Inconel and Monel alloys. Rose Metal Industries ensures that all products are accompanied by Mill Test Certificates (MTC) and comply with global quality standards.
Mechanical Properties: High Nickel Alloy Square Rods exhibit high tensile strength, yield strength, and elongation. Nickel 200/201 rods typically have tensile strengths ranging from 520–650 MPa and yield strengths from 220–300 MPa. These rods are also ductile and can be machined, welded, or fabricated as per project requirements, providing versatility in manufacturing pipelines, valves, fasteners, and structural components..
Our High Nickel Alloy Square Rods are produced using high-grade materials such as Nickel 200, Nickel 201, Inconel, and Monel alloys. These rods are engineered to provide exceptional resistance against oxidizing and reducing environments, acids, and alkaline solutions. The precision manufacturing processes, including hot-rolled and cold-drawn techniques, ensure dimensional accuracy, uniform surface finish, and excellent mechanical properties..
