High-performance stainless steel 17-4 PH pipes for demanding industrial applications are the speciality of Vinit Stainless, a well-known manufacturer and supplier with headquarters in Chennai, India. These pipes are perfect for critical environments because of their remarkable strength, hardness, and resistance to corrosion. Vinit Stainless uses sophisticated procedures and strict quality control when manufacturing 17-4 PH pipes to guarantee exceptional dimensional accuracy and dependability. Vinit Stainless is dedicated to quality, timely delivery, and customer satisfaction. It serves a variety of industries in India and abroad, such as power generation, petrochemical, marine, and aerospace.
15–17.5% chromium, 3–5% nickel, 3–5% copper, and trace amounts of niobium for precipitation hardening make up stainless steel 17-4 PH pipes. These pipes have outstanding toughness and hardness, as well as high tensile strength up to 1100 MPa and yield strength of about 1000 MPa (in H900 condition). They offer good corrosion resistance in both oxidising and reducing environments and retain their strength at high temperatures. Furthermore, 17-4 PH pipes are suitable for high-load and high-performance applications due to their good weldability, machinability, and dimensional stability under heat treatment.
