Harshita Stainless is a specialized manufacturer and exporter of SS 13-8 PH Sheets and Plates, operating in Dubai and India. Known for high strength, excellent toughness, and good corrosion resistance, 13-8 PH (UNS S13800) stainless steel is a martensitic precipitation-hardening alloy used in aerospace, petrochemical, and marine industries. Our sheets and plates undergo heat treatment and solution annealing to meet AMS and ASTM specifications. With a variety of thicknesses and dimensions available, Harshita Stainless provides reliable, aerospace-grade stainless steel plates that meet strict mechanical and metallurgical standards for critical load-bearing structures.
SS 13-8 PH contains 13% chromium, 8% nickel, and 1.1% aluminum, along with small amounts of molybdenum and carbon. After heat treatment (H950–H1150), it achieves tensile strength of 1000–1400 MPa and yield strength from 965 to 1310 MPa, with elongation of 8–18%, depending on temper. It shows high notch toughness and great stress corrosion resistance in marine and aerospace environments. Its blend of strength, ductility, and hardness is unmatched among precipitation-hardening stainless steels, making it ideal for structural and pressure-retaining applications.
