Exceptional Mechanical Properties

13-8 PH round bars boast a minimum yield strength of 1170 MPa and tensile strengths up to 1240 MPa in H1000 condition. Their unique composition of chromium, nickel, and aluminum grants not only remarkable strength but also excellent corrosion and heat resistance, ensuring performance in critical, high-stress applications. With a hardness range of 38-44 HRC, these bars remain reliable under varying mechanical demands.


Versatile Applications Across Industries

These round bars find widespread uses in aerospace manufacturing, chemical processing, and structural engineering, where resistance to corrosion and sustained mechanical strength are essential. Available in customizable diameters, lengths, and heat-treated conditions, 13-8 PH round bars can be tailored to meet specific requirements, making them versatile for precision machining, fabrication, and high-strength component production.


Superior Finish and Ease of Machining

With a bright, polished finish and smooth surface, 13-8 PH round bars offer excellent machinabilityespecially in the solution-treated condition. Their slightly magnetic properties and consistent dimensional tolerances support precision work, while the uncoated, pickled, or polished surfaces promote usability in various industrial processes. These features facilitate fabrication and ensure quality outcomes in high-performance environments.

FAQs of Stainless Steel 13-8 PH Round Bars:


Q: How are Stainless Steel 13-8 PH Round Bars supplied and processed?

A: The bars are available in solution annealed (Condition A), H1000, H1150, or custom heat-treated conditions. They are produced using hot rolled or cold finished methods to meet ASTM A564 and AMS 5629 standards, ensuring optimal mechanical properties for various applications.

Q: What makes 13-8 PH stainless steel suitable for high-stress applications?

A: Its compositioncombining chromium, nickel, and aluminumdelivers superior mechanical strength (minimum 1170 MPa yield), excellent corrosion resistance, and sustained hardness, making it ideal for aerospace, structural, and chemical environments where reliability under stress is crucial.

Q: When should customized heat treatments be selected for these round bars?

A: Customized heat treatments are recommended when specific mechanical properties, such as yield strength, hardness, or magnetism, are required for specialized industrial applications. Consulting with engineers allows tailoring the bars to project needs.

Q: Where are these round bars predominantly used?

A: Stainless Steel 13-8 PH round bars are mainly employed in aerospace components, structural frameworks, chemical process equipment, and other high-strength, corrosive, or heat-resistant environments.

Q: What diameters and lengths can be ordered for 13-8 PH round bars?

A: Customers can select bars in standard diameters from 8 mm to 250 mm, with lengths ranging from 2 m to 6 m. Custom sizes are also available based on specific project requirements, supporting flexibility in design and fabrication.

Q: How does the magnetic property of 13-8 PH round bars affect usage?

A: The bars are slightly magnetic in certain tempers, particularly after specific heat treatments. This property can be advantageous for certain industrial processes and does not compromise their mechanical or corrosion-resistant qualities.
