ASTM A789 S32205 Seamless Duplex Steel Heat Exchanger Tubes
TONG CHUANG Group offers ASME SA789 / ASTM A789 S32205 SMLS duplex stainless steel tubes and we sell these tubes in many years. This specification covers grades of nominal wall thickness， stainless steel tubing for services requiring general corrosion resistance， with particular emphasis on resistance to stress corrosion cracking. These steels are susceptible to embrittlement if used for prolonged periods at elevated temperatures.
