A review was made of the fracture toughness (K sub lc1 and stress corrosion (K sub Iscc) characteristics of 4340 steel within the 200 to 250 ksi yield strengh range. This literature review was conducted in support of a fracture mechanics and environmental investigation of 4340 steel for the control section housing, of the Copperhead CLGP (Cannon-Launched Guided Projectile) weapon system. Factors affecting toughness and corrosion cracking characteristics are considered. Also included are data pertaining to the damaging effects of humidity. Fracture toughness and stress corrosion cracking resistance of 4340 steel are usually higher in the alloys prosessing lower yield strengths. (Peters)
