Harsh Flanges, based in Mumbai, India, stands out as a top manufacturer and supplier of Hastelloy Forged Flanges, providing top-notch solutions for industries that operate in harsh, corrosive, and high-temperature settings. Crafted from high-performance nickel-based alloys like Hastelloy C-22 and C-276, these flanges offer remarkable mechanical strength, exceptional resistance to corrosion, and dependable performance even in extreme conditions. Our Hastelloy forged flanges are built to comply with global standards such as ASTM, ASME, and DIN. At Harsh Flanges, we prioritize quality, precision, and customer satisfaction, offering both custom and standard flange configurations for the chemical processing, marine, pharmaceutical, and power generation sectors around the globe.
Hastelloy Forged Flanges are made from nickel-molybdenum-chromium alloys like Hastelloy C-276 and C-22. These alloys generally consist of about 57% nickel, 15–17% molybdenum, and 14–16% chromium, along with trace elements like iron and tungsten to boost corrosion resistance. Their mechanical properties include impressive tensile strength (up to 790 MPa), excellent yield strength (around 355 MPa), and remarkable resistance to pitting, crevice corrosion, and stress corrosion cracking. The forging process enhances the grain structure and mechanical durability, making these flanges perfect for high-stress, high-temperature, and chemically aggressive applications in demanding industrial settings.
