SS 15 Round Rods

SS 15-5PH Round Rods are high-performance precipitation hardening stainless steel products designed for structural and mechanical applications requiring elevated strength, corrosion resistance, and toughness. Composed primarily of chromium, nickel, and copper, this alloy belongs to the martensitic family of stainless steels and is a refined version of 17-4PH, offering improved transverse properties and higher reliability in critical applications. The "15-5" designation refers to its nominal composition of 15% chromium and 5% nickel, with copper added to facilitate precipitation hardening through heat treatment.

One of the most notable attributes of SS 15-5PH is its ability to achieve a wide range of mechanical properties through various heat treatments, specifically the H900 to H1150 conditions. It exhibits a minimum yield strength of up to 1310 MPa (190 ksi) in the H900 condition, making it ideal for load-bearing environments. The alloy maintains excellent dimensional stability during hardening and does not suffer significant distortion—an essential factor for precision-engineered components. Its uniform structure also allows for superior machinability and weldability compared to many other martensitic stainless grades.

SS 15-5PH round rods are produced in hot-rolled, cold-drawn, and machined forms, available in diameters ranging from small precision rods to heavy-duty industrial bars. Surface finishes include black, bright, ground, and centerless-turned, each tailored for different functional requirements. Adhering to global standards such as ASTM A564 and AMS 5659, these bars offer excellent reliability in quality-sensitive applications. Our supply network ensures efficient and consistent delivery across India, the UAE, Saudi Arabia, Kuwait, Qatar, Oman, Iran, and Iraq, complete with full mill test certifications and traceability documentation.

Applications

SS 15-5PH Round Bars and Rods are widely utilized in demanding applications that require a high strength-to-weight ratio, resistance to stress corrosion cracking, and long-term structural stability. A key area of use is in aerospace engineering, where components such as landing gear parts, actuator shafts, and engine fittings are machined from this alloy due to its excellent fatigue resistance and performance under cyclic loading. The high tensile strength and fracture toughness ensure durability under extreme flight conditions, while its corrosion resistance makes it suitable for exposure to varied environmental factors, including humidity and salt spray.

In the industrial tooling and manufacturing domain, stainless steel round bars and rods 15-5PH is chosen for high-precision shafts, mandrels, and fasteners that must maintain strength and dimensional integrity over extended periods. Its excellent machinability in the H1025 condition makes it a preferred material for parts that undergo close-tolerance machining. Additionally, its hardenability enables custom heat treatments based on specific end-use demands, optimizing performance for hydraulic fittings, chemical processing equipment, and nuclear reactor components where safety and reliability are non-negotiable.

SS 15-5PH is also gaining prominence in the marine and offshore sectors, where parts are frequently exposed to brine, fluctuating pressure, and corrosive atmospheres. Components such as propeller shafts, pump shafts, and high-load brackets benefit from the alloy’s strength and resistance to crevice corrosion. Moreover, the ability to customize hardness and tensile properties allows engineers to design long-lasting solutions for submerged and semi-submerged applications, especially important for installations across coastal and offshore operations in the Gulf countries.

Industry Use

The versatility of SS 15-5PH Round Bars and Rods allows them to serve a broad range of industries that prioritize durability, precision, and corrosion resistance. In the aerospace and defense sectors, particularly across India and the Middle East, these bars are utilized in structural components, control systems, and satellite hardware that demand both mechanical strength and dimensional accuracy. Their consistent performance across temperature extremes and exposure to dynamic stress makes them indispensable for mission-critical components.

In the oil and gas industry, especially in regions such as Saudi Arabia, the UAE, and Kuwait, SS 15-5PH finds applications in downhole tools, pressure housings, and valve components used in both upstream and midstream operations. These environments involve constant exposure to corrosive fluids, high pressures, and temperature fluctuations—conditions that this alloy handles with remarkable resilience. Its resistance to stress corrosion cracking is particularly advantageous for deep well and sour gas conditions.

The power generation and energy sector, including nuclear and renewable infrastructure in India and Iran, also benefits from the alloy’s strength and stability. It is used in turbine parts, boiler components, and reactor internals where failure is not an option. Additionally, medical device manufacturing, particularly for surgical tools and orthopedic instruments, leverages the alloy’s biocompatibility, non-magnetic properties, and ease of sterilization. The presence of a well-established supply chain across India, UAE, KSA, Oman, Qatar, Iran, and Iraq ensures timely availability of SS 15-5PH round bars for both large-scale industrial projects and specialized engineering needs.
