Susceptibility of Grade 8 Fasteners to Stress Corrosion Cracking

Abstract

A brief historical review of the development of Plane Strain, Elastic, Fracture Mechanics is presented. Fracture toughness parameter, K (sub I c*) and stress corrosion cracking threshold level (parameter) K (sub I scc) are introduced and elaborated upon. The use of Fracture Mechanics - via the K (sub I scc) concept - to assess the resistance of low alloy steel to stress corrosion cracking in hostile environments is outlined and referenced. Based on the data presented in this report, it is concludes that zinc plated, low alloy steel fasteners below one inch in diameter, in the yield strength range of 130 to 160 ksi are immune to stress corrosion cracking in sea water environment.
