With increasingly stringent CO2-emission standards in the U.S., OEMs and system suppliers are seeking lightweight solutions. Forging and forging steel technology can greatly contribute to lightweight design in passenger cars and light-duty vehicles (as reported in FORGE earlier this year). A project funded by FIERF and AISI in the U.S. has shown likewise for heavy-truck forgings. The Lightweight Forging Initiative now wants to take the next step. In the third multilateral industrial project the scope shall be broadened in three directions: the Lightweight Forging Initiative should go international by uniting North American, Japanese and European steelmaking and forging companies; the powertrain of the vehicle in the analysis should be a hybrid powertrain after analyzing diesel combustion powertrains in the first two phases; and the application of carburizing steels in transmission should be analyzed in more detail because carburizing steel is one of the multipliers for lightweight forged products.
