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.
The three types of stress are acute stress, episodic acute stress, and chronic stress. Acute stress is a short-term form that arises from immediate challenges or pressures, while episodic acute stress occurs when someone frequently experiences acute stress, leading to a pattern of stress responses. Chronic stress, on the other hand, results from ongoing situations that are perceived as unmanageable, such as long-term financial issues or enduring relationships problems. Each type can impact mental and physical health differently, necessitating various coping strategies.
They are all mechanical stresses. Push is a compressive stress. Pull is a tensile stress and Twist is a type of shear stress.
Forgability is the ability of a material, typically a metal, to be shaped or deformed under compressive stress without cracking or breaking. It is an important property in processes like forging, where materials are heated and shaped into desired forms. The degree of forgability depends on factors such as temperature, material composition, and strain rate. Materials with high forgability can be easily manipulated into complex shapes while maintaining structural integrity.
Loctite No 30447 and Primer No 12695 can potentially affect polycarbonate even when not in direct contact, due to the release of volatile components that may cause stress cracking or clouding of the material. It is advisable to conduct compatibility tests or consult the manufacturer's guidelines to ensure safe use. To minimize risk, keep polycarbonate surfaces away from areas where these products are applied.

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.
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

Ammonia can cause stress corrosion cracking in steel, especially in the presence of water and oxygen. It can also lead to pitting and general corrosion of steel surfaces. Additionally, ammonia can weaken the mechanical properties of steel over time.
