Stainless Steel 17-4 PH Round Bar Manufacturer, Stainless Steel 17-4 PH Round Bar, Stainless Steel 17-4 PH Round Bar in India, Stainless Steel 17-4 PH Round Bar in Mumbai
Stainless Steel 17-4 PH Round Bar is a precipitation-hardening martensitic stainless steel that delivers an excellent combination of high strength, corrosion resistance, and ease of fabrication. Labdhi Metals, a leading manufacturer, stockist, and exporter, provides top-quality 17-4 PH round bars to customers across industries such as aerospace, petrochemicals, marine, oil & gas, and more. Their bars are available in a wide range of sizes and are precisely manufactured to meet global standards.
Labdhi Metals is known for its state-of-the-art production facilities and strict quality control processes. Each 17-4 PH round bar undergoes thorough inspection and testing to ensure dimensional accuracy, material integrity, and performance. These bars are often used in environments where high strength and moderate corrosion resistance are required, especially in applications where parts are exposed to stress, fatigue, and corrosive media.
17-4 PH, also referred to as UNS S17400, contains a blend of chromium, nickel, and copper, which provides superior corrosion resistance similar to austenitic grades but with much higher strength after heat treatment. The alloy can be hardened to various strength levels by different aging treatments (H900 to H1150), allowing manufacturers flexibility based on application needs.
Labdhi Metals exports 17-4 PH round bars worldwide, including to markets in the USA, Europe, the Middle East, and Southeast Asia. Their ability to supply custom-cut lengths, surface finishes (bright, black, peeled), and fast delivery timelines makes them a preferred supplier for both OEMs and stockists.
