We serve industries needing high-strength and corrosion-resistant materials and are renowned for providing exceptional quality and accuracy. Our 13-8 PH stainless steel circles are made with cutting-edge manufacturing techniques to satisfy the exacting requirements of the defence, petrochemical, and aerospace industries. Kunj Sheets and Plates is a preferred partner for clients throughout India and international markets because of our strong emphasis on customer satisfaction, prompt delivery, and customised solutions, which guarantee consistent product performance and reliability.
The main constituents of Stainless Steel 13-8 PH Circle, a precipitation-hardening martensitic stainless steel alloy with a low carbon content, are aluminium (0.9–1.35%), nickel (7.5–8.5%), and chromium (12.25–13.25%). It has outstanding strength, durability, and resistance to corrosion and cracking under stress. It can reach yield strength above 1250 MPa and tensile strength up to 1400 MPa after heat treatment. It is perfect for critical applications due to its high hardness and excellent transverse properties. The material’s versatility in demanding environments is further enhanced by its good formability and weldability.
