The stress corrosion cracking occurs only under the combined action of tensile stresses and corrosive environments [10] and must be considered as the emergent properties effect.
Duplex Steel has 2 times greater strength of resistance as compared to other authentic stainless steel and also helps in Improving resistance mainly to fight against corrosion and stress corrosion cracking.

The common corrosion types are mainly galvanic corrosion, pitting corrosion, filiform corrosion and stress corrosion of these.
CNA-Q and Qatar Petroleum officials have agreed to extend the research project to help identify which materials used in the energy sector are most resistant to chloride stress corrosion cracking.
Sandvik says the high strength, austenitic nickel-chromium alloy Sanicro 60 (UNS N06625), exhibits very good resistance to pitting corrosion, intergranular corrosion and is virtually immune to stress corrosion cracking (SCC) in chloride containing environments.
Corrosion that starts with pitting can ultimately progress into cracks in the metal, which can be accelerated by tensile stress, resulting in stress corrosion.
The analysis of three corrosion phenomena (uniform corrosion, pitting corrosion and stress corrosion cracking) has been carried out through the use of acoustic emission technique.
Some surface corrosion and stress corrosion cracking also were present, but they were not considered as contributing to the pipe failure.
Formation of the intergranular networks of carbon-hydride like compounds at grain boundaries during the ageing of pipe steel is one of the main reasons causing the change of material properties and creating favourable conditions for formation of structures with defects, initiation of stress corrosion and rise of intensity of electrochemical processes that cause corrosion.
Therefore stainless steels such as 6 Moly and Duplex which have a high corrosion resistance--particularly to stress corrosion cracking--are becoming more common across the industry.
