DUPLEX 2507 STAINLESS STEEL Duplex 2507 (UNS S32750) is a super duplex stainless steel with 25% chromium, 4% molybdenum, and 7% nickel designed for demanding applications which require exceptional strength and corrosion resistance, such as chemical process, 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

ASTM A240 UNS S32760 Steel Pipe ASTM A240 UNS S32760 Plate is a super duplex grade stainless steel alloy made for specific applications. Super duplex is a grading of duplex steel which is a combination of ferrite and austenitic steel types. By combining the structures of ferrite and austenite steels, a remarkable corrosion resistance along with high tensile strength is achieved. SA 240 UNS S32760 Sheet is used in ships, tanks and containers to deploy in most of the surfaces

ASTM A790 UNS S32750 Welded Pipe ASTM A790 UNS S32750 is a variation of super duplex steel. The duplex steel material is made up of chromium and molybdenum alloy. The duplex has the ferritic and austenitic steel properties in its metallurgic microstructure. This gives the name duplex to the material. The SA 790 UNS S32750 belongs to the super duplex category. There are three groups of duplex, namely the duplex, super duplex and lean duplex. Each of them has their own

ASTM A240 UNS S32760 Steel Pipe DUPLEX S32760 STAINLESS STEEL PIPE BRIEF INTRODUCTION DUPLEX S32760 STAINLESS STEEL PIPE is a high-alloy super duplex stainless steel, with strong steel strength and corrosion resistance, excellent overall performance S32760 (F55,1.4501) Super duplex stainless steel Overview: Kcm Special Steel co.,Ltd duplex S32760 stainless steel pipe (F55,1.4501) is a high alloy super duplex stainless steel, mainly used in a variety of strong corrosive

DUPLEX 2507 STAINLESS STEEL PIPE SUPER DUPLEX 2507 STAINLESS STEEL PIPE is a ferritic-austenitic (biphasic) stainless steel that combines the most beneficial properties of many ferritic and austenitic steels because of their high levels of chromium and molybdenum The ability to resist pitting corrosion, crevice corrosion and uniform corrosion.The biphasic microstructure ensures that the steel has a high resistance to stress corrosion cracking, and the mechanical strength is

Duplex S31803 Seamless Pipe The ASTM A789 UNS S31803 tubing refers to seamless and welded tubing manufactured in accordance with ASTM A789/ASTM A1789M, which contains approximately 50% ferrite and 50% austenite. The stress corrosion resistance of ASTM A789 in neutral chloride solution and H2S is better than that of 304L, 316L austenitic stainless steel, and 18-5mo type duplex stainless steel. The UNS S31803 tubing is especially suitable for the temperature range of -50°F/+600
