Chanchai Stainless is a well-respected manufacturer and supplier of stainless steel in Bangkok, Thailand. They specialize in high-quality Stainless Steel 17-7 PH Flanges, perfect for tough industrial applications. These flanges are celebrated for their impressive strength, resistance to corrosion, and long-lasting durability, making them ideal for both high-pressure and high-temperature settings. Thanks to their precipitation-hardening properties, SS 17-7 PH Flanges deliver outstanding mechanical performance and stability. Crafted with precision to meet international standards, they guarantee secure and leak-proof connections in piping systems. At Chanchai Stainless, we’re dedicated to providing cost-effective, durable stainless steel solutions for industries like aerospace, petrochemical, marine, and construction.
Stainless Steel 17-7 PH Flanges are made up of chromium (16–18%), nickel (6.5–7.75%), and aluminum (0.75–1.5%), which allow for precipitation hardening. They also contain trace amounts of carbon, manganese, silicon, and iron to enhance strength and toughness. These flanges boast a tensile strength of up to 1310 MPa and a yield strength of around 1170 MPa after heat treatment, along with excellent hardness and fatigue resistance. With good ductility, oxidation resistance, and long-term stability at high temperatures, SS 17-7 PH Flanges are perfect for critical piping applications that require strength, reliability, and corrosion resistance.
