DONGSHANG Stainless produce ASTM A213 duplex stainless steel tube applied for boiler, heat exchanger, super heater, stainless grades cover alloy steel, Ferritic steel and Austenitic steel, duplex steels are also used for seamless stainless steel tube in specific applications, duplex steels have more high strength and excellent corrosion resistance.
S31803, 2205, S32750, S32760 and other duplex grades are custom material for ASTM A213 / ASME SA213 seamless tubes, these Ferritic / Austenitic steels are high chromium and molybdenum low nickel content compared with 18 – 8 stainless steels, more thin thickness bring high cost effective, so duplex tubes widely used in oil, gas, chemical , petrifaction industries heating system, super duplex steels are more effective, duplex steel features and mechanical properties, see more duplex stainless steel pipe and 2205 stainless steel pipe.
ASTM A213 is a specification for seamless stainless steel tube applied in heat exchanger, boiler, super heater, grades not include duplex stainless steel grades, considering features and advantages in duplex steels, it is can be used for tubes in many industries, A789 and A790 are specifications for duplex stainless steel tubes and pipes for general service.
