Introduction

Stainless Steel Super Duplex 2507 pipe fittings are engineered for highly corrosive and high-pressure environments. With excellent mechanical strength, outstanding resistance to chloride stress corrosion, and superior weldability, these fittings are ideal for chemical processing, offshore oil rigs, desalination plants, and marine systems.

Mcneil Instruments stands as a trusted manufacturer, supplier, and exporter of Super Duplex 2507 pipe fittings in India. Our products are precision-engineered to meet global standards, ensuring long-term durability and safety in harsh environments.

What is Stainless Steel Super Duplex 2507 Pipe Fittings

Stainless Steel Super Duplex 2507 pipe fittings are components made from a high-performance duplex stainless steel alloy, known for its exceptional strength and corrosion resistance, especially in chloride-containing environments. Specifically, “2507” refers to the UNS designation (S32750), indicating a super duplex stainless steel with a high proportion of chromium, molybdenum, and nitrogen. These fittings are used to join, regulate, or terminate piping systems, and are designed to withstand harsh conditions in industries like petrochemical, chemical processing, and marine applications.

What Makes Super Duplex 2507 Exceptional

Super Duplex 2507 combines the benefits of both austenitic and ferritic stainless steels. It contains 25% chromium, 4% molybdenum, and 7% nickel, which enhances its resistance to pitting, crevice corrosion, and stress corrosion cracking—especially in chloride-rich environments.

Key Features:

  • High yield strength (almost double that of austenitic grades)
  • Excellent corrosion resistance in seawater and aggressive media
  • Superior mechanical strength and fatigue resistance
  • Good weldability and thermal conductivity
