  • Corrosion Fatigue in Boiler Tubes – Thielsch Engineering

    Oct 28, 2018 · Corrosion fatigue failures result from cyclic stressing of metal in a corrosive environment. This condition causes more rapid failure than that caused by either cyclic stressing or corrosion alone. In boilers, corrosion fatigue cracking can result from the continued breakdown of protective magnetite film due to cyclic stresses.Get Price
