The strength of our 347/347H pipes comes from a specific composition that includes columbium (niobium), which acts as a stabilizer. This clever addition provides outstanding resistance to intergranular corrosion following exposure to high temperatures. This means the material maintains its integrity and mechanical strength, such as excellent tensile and yield strength, under intense heat and stress. Essentially, this chemistry creates a pipe that is tougher and more resilient, preventing the weaknesses that can occur in other steels under similar demanding conditions.
