Super Duplex Hex Bar

Super duplex hex bar specifications

How is a Super Duplex Hex Bar manufactured? Which production processes are involved?

Sturdy, resilient, and long-lasting, these bars are perfect for demanding roles in offshore oil drilling, pharmaceuticals, and seawater equipment. The composition of a super duplex hex bar is generally 25% chromium, 7% nickel, and molybdenum up to 4%. It gets produced via hot rolling or cold forming, where the latter uses compressive forces.

The main production processes for hot-rolled UNS S32760 hex bars are:

  • Heating the steel billet above its recrystallisation temperature
  • Rolling it into the desired shape
  • Atmospheric cooling
  • Quenching and tempering
  • Cutting to client-specified length

Manufacturing a super duplex 2507 hex bar requires adherence to strict norms and tight tolerances. We follow global standards, like ASTM and DIN, to cater to international clients.

How is a Super Duplex Hex Bar used in the gas industry? What are the key advantages of this material for this application?

The oil and gas industry requires corrosion-resistant materials that handle extreme temperatures and pressures. Super duplex S32750 hex bars work in rock-breaking oil platforms, flue gas scrubbing equipment, petrochemical equipment, and waste gas purification.

Besides corrosion resistance, ASTM A276 super duplex hex bars have numerous benefits for this sector:

  • A low coefficient of thermal expansion
  • High fatigue and pitting resistance
  • Can handle up to 300°C
  • Excellent tensile and impact strength

A super duplex steel hex bar can comfortably work in deep oil wells, rigs, and areas with high-brine levels.

What is the testing protocol used for a Super Duplex Hex Bar? How does it ensure the quality and performance of the product?

The prime goal of testing a zeron 100 UNS S32760 hex bar is ascertaining compliance with international standards, dimensional tolerance, and customer specifications. These products get subjected to positive material identification, radiography, and ultrasonic testing. ASTM A276 UNS S32760 hex bar manufacturers also manipulatively assess strength, hardness, corrosion resistance, and flattening/flaring.

We issue a detailed MTR with UNS S32750 hexagon bars and associated documentation, including certificates for raw materials, country of origin, and radiography.
