Dhruv Metals, based in Hyderabad, India, stands out as a top manufacturer and supplier of Stainless Steel 17-4 PH Bars and Rods. These products are celebrated for their remarkable strength, hardness, and resistance to corrosion. The 17-4 PH (Precipitation Hardening) stainless steel is a martensitic grade that can be heat-treated to achieve impressive mechanical properties while still offering solid corrosion resistance. At Dhruv Metals, we take pride in producing SS 17-4 PH bars and rods with precision and consistency, serving industries like aerospace, petrochemical, nuclear, and marine engineering.
Typically, Stainless Steel 17-4 PH Bars and Rods consist of chromium (15.0–17.5%), nickel (3.0–5.0%), copper (3.0–5.0%), and a controlled carbon content (≤0.07%), along with trace elements like niobium, manganese, silicon, phosphorus, and sulfur. These bars boast an impressive tensile strength of up to 1310 MPa, a yield strength of around 1170 MPa (post heat treatment), an elongation of 10–20%, and a hardness that can reach up to 44 HRC, depending on the heat treatment conditions (like H900 or H1150).

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.
Stainless Steel 17-4 PH Bars and Rods find their place in critical applications that require high strength, wear resistance, and moderate corrosion protection. They are commonly used in turbine components, shafts, fasteners, pump parts, valve stems, nuclear waste casks, and aerospace fittings. Thanks to their ability to be hardened through heat treatment without distortion, 17-4 PH is perfect for precision parts in high-stress and corrosive environments. Its outstanding mechanical properties, along with good machinability and weldability, make it a preferred choice for demanding engineering applications.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
