Testing of the susceptibility of advanced high strength steel sheets to hydrogen induced cracking - Constant Load Test

    VDA 238-202 - Testing of the susceptibility of advanced high strength steel sheets to hydrogen induced cracking - Constant Load Test

    This document describes the Constant Load Test (CLT) for testing and evaluating the susceptibility of sheet steels to hydrogen-induced brittle fracture ("hydrogen embrittlement"). In the CLT, a constant mechanical load is applied in corrosive surroundings to simulate the conditions during the vehicle manufacturing process (press shop, body shop, and paint shop) and the life cycle of the vehicles (operating loads and corrosion).
