5/16 Duplex 2507 Ss Stainless Steel Coiled Tubing
5 / 16 * 0.035 Stainless Steel Coiled Control Line Tube Duplex 2507 for oil & Gas
Tiptop offers a variety of duplex stainless steel, super duplex stainless steel welded and seamless tubing, depending upon the properties the tubing is required to exhibit. Other alloys and sizes are also available upon request. Duplex stainless steels (named for their austenite and ferrite compositions), has greater yield strength than austenitic stainless steel.
Standard: ASTM-A 789 Standard specification for seamless and welded ferretic/austenitic stainless steel tubing for general service. This specification covers various grades of duplex stainless steels.

Duplex 2507 (UNS S32750) is a super duplex stainless steel designed for applications which require exceptional strength and corrosion resistance. 2507 is a 25% chromium, 4% molybdenum, and 7% nickel alloy resulting in excellent resistance to chloride pitting and crevice corrosion attack. The duplex structure provides 2507 with exceptional resistance to pitting and chloride stress corrosion cracking.
Usage of 2507 should be limited to applications below 600° F (316° C). Extended exposure to elevated temperatures can reduce its toughness and corrosion resistance.
Features:
High resistance to chloride stress corrosion cracking
Strong resistance to chloride pitting and crevice corrosion
High strength
Strong general corrosion resistance
Suggested for applications up to 600° F
Good weld ability / work ability
Resistant to pitting and crevice corrosion in seawater
Applications:
Marine Applications
Offshore Oil production/technology
Oil and gas industry equipment
