Resistive weldability of high-strength steel 22MnB5 is very important for automotive industry. Coated steel is galvanized. Al-Si coating protects the steel against oxidation during forming. At the interface of Al-Si coating and basic material the diffusion layer is created. The layer thickness depends on temperature and holding time of heat treatment. The contribution deals with chemical composition of coating (including diffusion layer) and its mechanical properties (indentation hardness H and elastic modulus E).Keywords: Resistive weldability, 22MnB5, Al-Si coating, diffusion layer
