Vishal Flanges stands out as a leading manufacturer and supplier of Stainless Steel 17-4 PH Flanges in Delhi, India, known for providing top-notch flanges tailored for high-performance industrial needs. The 17-4 PH alloy is a precipitation-hardening stainless steel that boasts an impressive mix of high strength, corrosion resistance, and solid mechanical properties even at elevated temperatures. These flanges are perfect for settings that demand toughness and dimensional stability. Vishal Flanges produces 17-4 PH flanges in line with international standards like ASME B16.5, ASTM A564, and ANSI, ensuring precision, durability, and reliability in challenging sectors such as aerospace, power generation, and petrochemicals.
Stainless Steel 17-4 PH flanges mainly consist of 17% chromium, 4% nickel, along with trace amounts of copper, niobium, and manganese. This unique alloy delivers remarkable tensile strength (930–1310 MPa) and yield strength (725–1170 MPa), which vary based on the heat treatment (H900–H1150). Additionally, 17-4 PH showcases excellent hardness, moderate resistance to corrosion, and good resistance to stress corrosion cracking, particularly in marine and chemical settings. It retains its mechanical integrity at temperatures reaching up to 600°F (316°C), making it a versatile choice for high-load and temperature-sensitive applications.
