Modern cold work tool steels for AHSS applications
Over the last few years there has been an increasing development in the automotive industry like PHEV (Plug- in Hybrid Electric Vehicles), BEV (Battery Electric Vehicles), FCEV (Fuel Cell Electric Vehicles), and ICE (Internal Combustion Engine vehicles). Independent on technology they are all striving for better fuel efficiency, lower emission, better crash safety and longer range.
These demands have driven the development in every link in the supplier chain for stronger, lighter or more efficient parts to build the car from. One example is “Advanced High-Strength Steels” (AHSS). The use of AHSS has lowered the weight of the cars body structure at the same time as the crash safety level has been raised.
How you can form AHSS?
From a tooling perspective, this has raised the demand on tool materials.
