Before going into service, high tensile steel chains are subjected to a manufacturing test load that causes plastic deformation and profoundly affects the chain's mechanical properties, particularly under fatigue loading. The residual stresses thus introduced have been calculated by the finite element method and compared with neutron diffraction measurements. Satisfactory agreement has been obtained.
