API 570 STUDY GUIDE  AMINE STRESS CORROSION CRACKING API 571 (3rd ED, Mar 2020) Amine Stress Corrosion cracking or Amine SCC or Amine Cracking Amine SCC is related to tensile stress, type of amine and temperature Amine SCC causes CRACKS in Carbon Steels and Low-alloy steels.  1. Description of Damage Amine SCC occurs by the combined action of tensile stress and an aqueous alkanolamine solution.  Note that pure alkanolamine does not cause Amine cracking so an aqueous alkanolamnie presence is needed for cracking to occur. Amine Cracking is a form of Alkaline Stress Corrosio ..read more
