ASTM A358 Stainless Steel TP347 / 347H CL.1 EFW Pipes

ASTM A 358 GR. TP 347 EFW welded pipe is a type of stainless steel pipe known for its high resistance to corrosion and high temperature. It is commonly used in petrochemical, gas, oil, and chemical refineries due to its durability and strength. ASTM A 358 GR. TP 347 EFW Welded Pipe comes in various types. One type is the ASTM A 358 GR. TP 347L EFW welded pipe. This type is composed of a lower carbon content material than TP 347. Its composition includes 0.03% carbon, 18% chromium, and 10% nickel. It is ideal for use in environments with high temperatures and stresses. It is known for its exceptional corrosion resistance and strength.
Another type is the ASTM A 358 GR. TP 347H EFW Welded Pipe. It has a higher amount of carbon, normally between 0.04%-0.1%. Its composition includes 18% chromium, 10% nickel, and 0.75% molybdenum. This type of pipe can be hardened through heat treatment, improving its strength and wear resistance. It is often used in industries that require high-temperature stability and low-temperature toughness.
