Nial Sheets and Plates, Houston, USA, is a well-established producer and distributor of high-quality metal products with precise engineering and a focus on quality. Among its star products is the Stainless Steel 13-8 PH Circle, a high-grade alloy circle engineered for rigorous industrial uses. With innovation and customer satisfaction given priority, Nial Sheets and Plates supply a global clientele with products that conform to international quality standards. Having a state-of-the-art manufacturing facility and quality control systems in place, it is possible for them to provide high-quality solutions to the critical sectors of aerospace, medical, marine, and petrochemical.
The Stainless Steel 13-8 PH Circle is a precipitation-hardening martensitic alloy made up of approximately 13% Chromium, 8% Nickel, 2% Molybdenum, and limited amounts of Aluminum. It possesses high mechanical strength, with tensile strength up to 2050 MPa in the H1025 condition and yield strength of approximately 1850 MPa. It has excellent toughness, good ductility, and high corrosion resistance, even in hostile environments. The material can also be heat-treated to different strengths, and it is thus very versatile and trustworthy for precision-oriented applications that need both strength and toughness.
