Neil Metals, based in Kolkata, India, has earned a solid reputation as a reliable manufacturer and supplier of Stainless Steel 17-4PH Forgings. These components are designed to be high-strength and corrosion-resistant, making them perfect for tough industrial applications. With their impressive mechanical properties and ability to harden through a single heat treatment, these forgings find their way into various sectors, including aerospace, marine, and chemical processing. Neil Metals offers 17-4PH forgings in a variety of shapes and sizes—think shafts, rings, discs, and even custom parts—while ensuring they meet international standards. Their commitment to precision, durability, and timely delivery means they consistently provide dependable forging solutions to both local and global clients.
When it comes to composition, Stainless Steel 17-4PH Forgings contain about 17% chromium and 4% nickel, along with copper and niobium (or columbium) for precipitation hardening. This alloy boasts remarkable mechanical strength, achieving tensile strength up to 1100 MPa and yield strength around 1000 MPa after heat treatment. It strikes a balance between high hardness, moderate corrosion resistance, and good toughness, even in tough environments. Plus, the material is magnetic and retains solid mechanical properties in both its base and hardened states.
