Duplex 2304 Stainless Steel Pipe

DescriptionDUPLEX 2304 STAINLESS STEEL PIPE BRIEF INTRODUCTIONDUPLEX 2304 STAINLESS STEEL PIPE / Duplex 2304 pipe is a low-alloy duplex stainless steel developed by Sweden.It has a solution temperature of about 1000 ℃, the organization has 40% -50% ferrite and 50% -60% austenite, with the common characteristics of duplex stainless steel, Is as a high strength and inexpensive features, can replace the 304L and 316L commonly used austenitic stainless steel and the development of steel.It has been recognized by the American Society of Mechanical Engineers (ASME) for use in boilers and pressure vessels, chemical plants and refineries, and many countries have incorporated standards.US standard for the UNS S32304, Sweden’s commercial grade SAF 2304 .UNS S32304 / SAF 2304 DUPLEX STAINLESS STEEL PIPE RELATED PRODUCTS OFFERING BY KCM SPECIAL STEEL1.
