Chloride Stress Corrosion Cracking Stainless Steel

Figure 1 shows the cracking that occurred on a 6mo super austenitic stainless steel n08367 exposed to 0 2 chlorides at 500 f 260 c.

Chloride stress corrosion cracking stainless steel. For example chloride stress corrosion cracking of austenitic stainless steel has been experienced in hot water jacketed pipes carrying molten chocolate in the food industry. It is difficult to control the temperature while changing pipe material or eliminating residual stresses associated with welding and forming the pipework is costly and. Chloride stress corrosion cracking cscc is a type of intergranular corrosion. Chloride stress corrosion is a type of intergranular corrosion and occurs in austenitic stainless steel under tensile stress in the presence of oxygen chloride ions and high temperature.

It occurs in austenitic stainless steel under tensile stress in the presence of oxygen chloride ions and high temperature. Chloride stress corrosion cracking cl scc is a type of stress corrosion cracking scc and is one of the most well known forms of scc in the refining and chemical processing industries. The typical crack morphology for chloride stress corrosion cracking consists of branched transgranular cracks. It can be detrimental to austenitic stainless steels one of the main reasons these steels are not considered a cure all for corrosion problems.

How to reduce the risk of stress corrosion cracking scc the risk of stress corrosion cracking scc can be minimized through plant and equipment design.
