    Tungsten is a relatively costly alloying element in steel and therefore it is used only sparingly for niche applications (e.g. tool steels), particularly for hardness improvements utilising its carbide phases. Thus, the literature on the W-containing automotive sheet steels is scanty and its metallurgical effects during processing of sheet steels is largely unknown. In the present work, a W-containing low-carbon steel containing 0.15C-2Mn-0.25W (wt.%) was designed using thermodynamic predictions and investigated for its suitability for hot-press forming (HPF). The alloy was processed to a cold-rolled gauge of 1.5 mm following standard industrial processing steps. The behaviour of the alloy during continuous cooling transformation (CCT) revealed that W retards the ferritic and pearlitic transformations from austenite.
