Their Stainless Steel 17-4 PH Bars and Rods are the go-to choice for critical environments that require top-notch mechanical properties, making them a trusted partner in fields like aerospace, chemical processing, and marine engineering.
Stainless Steel 17-4 PH Bars and Rods are a type of martensitic precipitation-hardening stainless steel, primarily made up of 15–17.5% chromium, 3–5% nickel, 3–5% copper, along with trace amounts of niobium and manganese. This unique blend gives them remarkable mechanical strength, hardness, and decent corrosion resistance. When heat-treated, their yield and tensile strength can soar to impressive levels, reaching up to 1000 MPa. They also maintain toughness and resist stress corrosion cracking, making them incredibly reliable in harsh operating conditions. Their excellent strength-to-weight ratio and versatility further boost their popularity across various industries.

Stainless Steel 17-4 PH Bars and Rods are known for their exceptional strength and corrosion resistance. The alloy undergoes a precipitation hardening process, which significantly enhances its tensile strength, yield strength, and fatigue resistance, making it ideal for demanding applications in aerospace, automotive, and other industries that require materials to withstand high-stress environments.
Yes, Stainless Steel 17-4 PH Bars and Rods can be heat treated to achieve various hardness levels and mechanical properties. The material is often solution annealed and then precipitation hardened to optimize strength, corrosion resistance, and toughness, depending on the specific requirements of the application.
These Stainless Steel 17-4 PH Bars and Rods find extensive applications in sectors that demand high strength and corrosion resistance. In the aerospace industry, they are used in turbine blades, shafts, and structural components, thanks to their ability to endure extreme conditions. The chemical and petrochemical sectors depend on them for valves, pumps, and fasteners that come into contact with corrosive substances. In marine engineering, they are essential for propeller shafts, gears, and offshore platforms due to their seawater resistance. Additionally, they play a vital role in paper production, power generation, and food processing equipment, highlighting their remarkable versatility.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
