A358 TP347 Stainless Steel EFW Pipes follow a series of standards, such as ASME SA-213/SA-213M, ASME SA-312/SA-312M, GB/T13296 and GB/T14976, etc.
A358 TP347 Stainless Steel Pipes have better performance after solution treatment (usually at 1000-1100℃). Solution treatment helps to eliminate the tendency of intergranular corrosion and improve corrosion resistance.
ASME SA358 SS 347 EFW Pipes are austenitic stainless steel with good weldability. However, due to its poor thermal conductivity and large linear expansion coefficient, problems such as hot cracking, reheating cracking, intergranular corrosion and stress corrosion should be considered during welding.
