Chloride Stress Corrosion (CSCC)

U-bend tests in chloride solutions evaluate susceptibility to stress corrosion cracking in service-like conditions.

Overview

Why chloride stress corrosion testing matters

Chloride stress corrosion cracking occurs when tensile stress combines with chloride-ion exposure, leading to cracking in stainless steels and other alloys—commonly in coastal, marine, or industrial environments. Testing helps identify prone materials before critical use.

Method

U-bend test setup

Metal specimens are bent into a U-shape and exposed to a chloride environment under tensile stress to simulate service conditions. This accelerates the onset of stress corrosion cracking for evaluation of durability and reliability.

Environments

Test solutions & temperature window

MgCl₂

Magnesium chloride

Exposure up to 500 °C, as specified for aggressive chloride conditions.

CaCl₂

Calcium chloride

Exposure up to 500 °C for accelerated assessment in chloride media.
