Chanchai Stainless, a top-notch stainless steel manufacturer and supplier located in Bangkok, Thailand, specializes in high-quality Stainless Steel 17-4 PH Sheets and Plates designed for critical industrial applications. Renowned for their impressive blend of strength, toughness, and resistance to corrosion, these sheets and plates are perfect for challenging environments. SS 17-4 PH is a precipitation-hardening stainless steel that boasts outstanding mechanical properties, even under high temperatures. At Chanchai Stainless, we prioritize precision manufacturing to meet international standards, providing cost-effective and durable stainless steel solutions for various industries, including aerospace, petrochemical, marine, power generation, and general engineering.
Stainless Steel 17-4 PH Sheets and Plates are mainly made up of chromium (15–17.5%), nickel (3–5%), and copper (3–5%), with niobium added for precipitation hardening. Carefully controlled levels of manganese, silicon, carbon, and phosphorus improve toughness and workability. After undergoing heat treatment, these sheets and plates can achieve a tensile strength of up to 1310 MPa and a yield strength of around 1170 MPa. They also exhibit excellent hardness, fatigue resistance, and corrosion resistance in environments containing chloride. With good ductility and long-term stability, SS 17-4 PH Sheets and Plates are ideal for high-stress, high-performance applications.
