17-4 PH Round Bars Manufacturer, Stockist and Exporter

15-5 PH Round Bars are precipitation-hardening stainless steel bars known for their excellent combination of high strength and corrosion resistance. They are widely used in aerospace, chemical processing, and petrochemical industries where both durability and resistance to stress corrosion are essential. These bars can be heat treated to achieve a wide range of mechanical properties. Their ability to maintain high toughness even at sub-zero temperatures makes them suitable for critical applications. The alloy’s low carbon content ensures reduced risk of sensitization during welding. With a polished surface finish, 15-5 PH bars are also preferred for aesthetic applications in architectural and marine environments.

Chemically, 15-5 PH stainless steel contains chromium, nickel, and copper, along with a small amount of niobium. Chromium provides excellent corrosion resistance and forms a protective passive oxide layer on the surface. Nickel contributes to toughness, formability, and overall strength. Copper enhances the precipitation-hardening effect, allowing the steel to achieve high strength after heat treatment. The niobium stabilizes the structure and prevents intergranular corrosion. Sulfur and phosphorus are kept at minimal levels to improve machinability and reduce brittleness. The precise chemical composition ensures uniform mechanical properties across all manufactured bars.

The mechanical properties of 15-5 PH Round Bars are impressive, especially after aging heat treatment. Tensile strength can reach up to 1,300 MPa depending on the specific temper. Yield strength is typically around 1,100 MPa, while elongation in 50 mm ranges from 10% to 12%. Hardness levels vary between 28 HRC to 42 HRC based on heat treatment conditions. The bars maintain excellent fatigue strength and resistance to stress corrosion cracking. They also exhibit good impact toughness, making them suitable for dynamic load applications. The material’s stability at elevated temperatures ensures long-term reliability in demanding conditions.

15-5 PH Round Bars are available in a wide range of diameters, typically from 6 mm up to 200 mm. Standard lengths range from 1 meter to 6 meters, with custom sizes available upon request. The bars are manufactured using precise forging and rolling processes to achieve uniformity and dimensional accuracy. Surface finishes include bright, polished, or machined, depending on application requirements. The bars can be further processed into shafts, pins, and fasteners without compromising strength. Tight tolerances make them ideal for high-precision applications in aerospace and medical devices. Their excellent weldability allows fabrication into complex structures without loss of mechanical properties.

Equivalent grades of 15-5 PH include stainless steels such as UNS S15500, ASTM A564, and SAE 631. These grades share similar chemical composition and mechanical properties, ensuring compatibility for replacement or substitution. Internationally recognized standards make it easier to source material from multiple suppliers. Material certificates typically include chemical analysis, mechanical test reports, and hardness values. Compliance with ASTM and AMS specifications guarantees reliability for critical engineering applications. These bars are often used as a benchmark for comparison with other precipitation-hardening stainless steels. Selecting the correct equivalent grade is crucial for maintaining performance in specific service environments.

Weight calculation of 15-5 PH Round Bars is straightforward using the formula: Weight (kg) = (Diameter² × 0.00617 × Length in mm). This allows engineers to estimate material requirements accurately for manufacturing and construction projects. Standard charts provide ready reference for common diameters and lengths. Understanding the weight helps in transport planning and ensures safety during handling. It also aids in cost estimation for large-scale production. Manufacturers often provide pre-weighed bars for easier inventory management. Using accurate weight calculations ensures precise material planning and reduces wastage.

15-5 PH Round Bars are widely recognized for their versatility and performance under demanding conditions. They are extensively used in aerospace components, chemical plant equipment, shafts, fasteners, and marine applications. The combination of high strength, corrosion resistance, and toughness makes them ideal for critical structural and functional parts. Regular maintenance and proper heat treatment further extend their service life. Their predictable mechanical behavior allows engineers to design with confidence. Overall, 15-5 PH bars offer a reliable solution for industries requiring precision, durability, and long-term performance in harsh environments.
