    Testing of finished high strength steel components for their susceptibility or resistance to stress corrosion cracking (SCC) provides data of immense value to designers and manufacturers. Reported in the literature are many different techniques of testing for SCC which have varying advantages and disadvantages. However, most techniques have been questioned on the grounds of applicability and reproducibility.

    A test which rapidly ranks similar components, in order of resistance to SCC, is in demand. Techniques which quantify the extent of damage, after a period of time, such as the breaking load method, are able to overcome some of the limitations of other SCC tests. The use of the breaking load method has been reported to provide reliable results in the comparison of certain aluminum alloys.

    This paper applies the breaking load method, a residual strength test, to high strength steel components. Bolts, rather than tensile test specimens, were used, to enable the effect of geometry and manufacturing methods on susceptibility to SCC to be studied. It is concluded that the breaking load method can be used to rank differences between materials, manufacturing methods and geometry.
