S32750 2507 Duplex Steel Wire Grade: S31803 ,S32205, S32507

Duplex Alloy 2507 Stainless Steel Wire UNS S32750

DUPLEX ALLOYS 2507 ALLOY DESCRIPTION

Duplex 2507 is a super duplex stainless steel with high strength and good corrosion resistance. It has excellent resistance to chloride stress corrosion cracking, high thermal conductivity, and a low coefficient of thermal expansion. The high chromium, molybdenum and nitrogen levels provide excellent resistance to pitting, crevice and general corrosion. The impact strength is also high. Duplex 2507 is not recommended for applications which require long exposures to temperatures above 600°F (316°C). Both toughness and corrosion resistance can be reduced.   Specifications of Super Duplex Steel Wire: Specifications : ASTM A580, Q_YT 101-2018 Grade:2205, 2507, S31803, S32205, S32750 Wire diameter : 0.1 to 5.0mm Type : Wire Bobbin, Wire Coil, Filler Wire, Coils, Wiremesh Surface: Bright, Dull Delivery state: Soft annealed – ¼ hard, ½ hard, ¾ hard, full hard   S32750 Duplex Steel Wire Chemical Composition:
