SCC - Stress Corrosion Cracking of Stainless Steel
Corrosion of stainless steel by hot caustic Research using solutions of chemically pure caustic (sodium hydroxide [NaOH]) led to the development of a diagram that attempts to delineate the param- eters of concentration and tem- perature governing stress corrosion cracking (SCC) of typeGet price
SSINA Stainless Steel Corrosion
Definition The combination of tensile stress and a specific corrosive environment can crack stainless steels. This mode of attack is termed stress corrosion cracking (SCC). The most common environmental exposure condition responsible for SCC of stainless steels is the presence of chlorides.Get price
Stress corrosion cracking - Wikipedia
Stress corrosion cracking. The stresses can be the result of the crevice loads due to stress concentration, or can be caused by the type of assembly or residual stresses from fabrication (e.g. cold working); the residual stresses can be relieved by annealing or other surface treatments.Get price

Chloride Stress Corrosion Cracking Swagelok
Chloride Stress Corrosion. Because of Swagelok's elevated chromium and nickel levels, Swagelok fittings can provide engineered combinations for certain applications as a rated alternative to full exotic alloy solutions. Raw materials matter. Whenever stainless steel is exposed to chloride concentrations and stress levels, Chloride Stress Corrosion Cracking (CSCC) can occur.Get price
Controlling stress corrosion cracking
Control of stress. As one of the requirements for stress corrosion cracking is the presence of stress in the components, one method of control is to eliminate that stress, or at least reduce it below the threshold stress for SCC. This is not usually feasible for working stresses (the stress that the component is intended to support),...Get price

Stress corrosion cracking (SCC) of 304 stainless steel (SS) in high-temperature water was in-situ monitored by analyzing acoustic emission (AE) waveform. Several SCC modes including transgranular SCC (TGSCC), intergranular SCC (IGSCC) and mixture of TGSCC and IGSCC were obtained by changing material state and controlling load mode, dissolved oxygen concentration.Get price
