17-4-PH Square Rods
Rose Metal Industries is a trusted manufacturer, stockist, and global exporter of high-quality 17-4 PH Square Rods (UNS S17400 / Grade 630), supplying industrial projects across Tamilnadu, Andhra Pradesh, Karnataka, Telangana, Puducherry (Pondicherry), and the Andaman & Nicobar Islands as well as to clients worldwide. 17-4 PH stainless steel combines high strength, hardness, and moderate corrosion resistance, making it suitable for marine, petrochemical, aerospace, and heavy engineering applications.
Our 17-4 PH Square Rods are produced with strict quality control using premium raw materials and advanced manufacturing techniques such as hot-rolling, cold-drawing, bright-polishing, and centerless grinding. These rods are available in a wide range of sizes to cater to diverse requirements from industrial fabricators, including applications in Chennai, Hyderabad, Bengaluru, Puducherry, and Port Blair.
After age-hardening heat treatment, 17-4 PH rods achieve exceptional mechanical strength and hardness, making them ideal for load-bearing and high-stress components. Their moderate corrosion resistance ensures long-lasting performance in coastal and chemical environments, making them a preferred choice for industries across Karnataka, Telangana, Andhra Pradesh, and Tamilnadu.
Rose Metal Industries provides customization options including diameters, square sizes, lengths, surface finishes, cut-to-length options, and export-ready packaging. Our products comply with international standards such as ASTM A564, ASTM A276, AMS 5604, and EN 1.4542, ensuring quality, traceability, and suitability for both domestic and overseas projects.
