Neil Metals, located in Kolkata, India, has earned a solid reputation as a reliable manufacturer and supplier of Stainless Steel 17-7 PH Bars and Rods. They’re well-known for producing high-performance precipitation-hardening stainless steel products that boast impressive strength, hardness, and resistance to corrosion. These bars and rods find their way into demanding applications across various sectors, including aerospace, chemical, and marine industries. Neil Metals offers 17-7 PH stainless steel in a range of sizes, conditions, and specifications, all designed to meet global quality standards. With a strong commitment to precision, consistent mechanical properties, and customer satisfaction, Neil Metals has positioned itself as a trusted supplier in both domestic and international markets.
The composition of Stainless Steel 17-7 PH Bars and Rods primarily includes iron, chromium (17%), and nickel (7%), along with some aluminum and carbon. This unique blend allows for precipitation hardening through heat treatment, resulting in a remarkable tensile strength of up to 1300 MPa, along with excellent fatigue and creep resistance. After heat treatment, the material maintains good formability and dimensional stability. It also offers moderate corrosion resistance, comparable to Type 304 stainless steel, making it suitable for both industrial and marine environments.
