Stress corrosion cracking is a form of localized corrosion that will affect metal causing sudden cracks. This forms of corrosion is typical of certain combination of metal-environments. For example Stainless Steel will crak in contact with Chloride at temperature above approx 60°C, Copper when in contact with ammonia or Carbon Steel in contact with Caustic Solutions.
Iron and steel rusting is an example of corrosion. Copper pitting or the green patina one sees on copper roofs are also examples of corrosion. Stress Cracking is also considered an example of corrosion.
They are all mechanical stresses. Push is a compressive stress. Pull is a tensile stress and Twist is a type of shear stress.
Nuts and bolts made up of the same metal are preferred because they have the same strength and stress resistance.
The over consolidation ratio or OCR is defined as the highest stress experienced divided by the current stress
The expression for the energy density in terms of stress and strain can be expressed as ρe.

Anodic current; temperature; acid; repeated stress (stress corrosion cracking); water; salts especially chlorides; a dissimilar metal placed in direct contact (galvanic corrosion). Poor painting (pinhole corrosion - concentrates all the anodic current in one small place) and others

Actually there is no threshold value for Chloride stress corrosion cracking in stainless steels. Generally chloride is a crucial threat for operation systems and there is no specific solution except oxygen scavenging that will reduce the cracking possibility. According to Shell degradation library, below 10 ppm in temperatures lower than 60 deg c, cracking susceptibility is low.
