Super Duplex Steel S32750 Forged Fittings are made from a high-grade duplex stainless steel containing chromium, nickel, molybdenum, and nitrogen. This dual-phase ferrite-austenite structure provides outstanding corrosion resistance against pitting, crevice corrosion, and stress corrosion cracking. The fittings offer excellent tensile and yield strength, high fatigue resistance, and long-term toughness. They maintain structural integrity under high pressure, temperature, and chemically aggressive environments. With superior dimensional stability, mechanical strength, and corrosion resistance, S32750 forged fittings are ideal for critical applications in oil and gas, chemical processing, marine, and power generation industries.
