347stainless steel pipe advantage
347 containing tantalum and niobium, mainly used in high temperature welding parts.347 stainless steel tube containing Nb to improve intergranular corrosion resistance, with increased strength, plasticity does not reduce. Reduce the thickness of the material.as a structural strength component》347 stainless steel is similar to 321 stainless steel in that it is often used as a stable replacement for Type 304. However, in the case of 347, the stabilizer is columbium. This metal enhances 347's already established ability to withstand intergranular corrosion for maximum performance. In addition, columbium allows 347 to be heated repeatedly at temperatures up to 1650° F. Therefore, the metal is commonly used in high-temperature equipment, such as gaskets and expansion joints, as well as rocket engines and chemical manufacturing.
