ASTM A789 Duplex 2507 Hydraulic Control Line

Duplex 2507, which is a super duplex stainless steel with 25% chromium, 4% molybdenum, and 7% nickel. This alloy is designed for applications which require exceptional strength and corrosion resistance; examples include applications in chemical processing, petrochemical, and seawater equipment. The steel has excellent resistance to chloride stress corrosion cracking, high thermal conductivity and a low coefficient of thermal expansion. The high chromium, molybdenum, and nickel levels provide excellent resistance to pitting, crevice, and general corrosion.

Duplex 2507 displays its superior performance in a number of aspects:

• Exceptional resistance to pitting and crevice corrosion
• High resistance to stress corrosion cracking in chloride bearing Environments
• Good sulfide stress corrosion resistance
• Greater resistance to hydrogen embrittlement
• Very high mechanical strength
• High energy absorption
• Low coefficient of thermal expansion
• Good workability and weldability

We are one of the leading suppliers of Super Duplex 2507 CoiledTubing in China. A lower content of carbon in 2507 tubing greatly reduces the risk of carbide precipitation, which can occur at the grain boundaries during heat treatment. 2507 super duplex stainless steel pipe is particularly useful in applications involving the offshore oil and gas industries as well as in wells with either naturally high brine levels or where brine solution has been injected to enhance recovery in these wells.
