Influence of Higher Tramp Element Level on the Weldability of Automotive Steels
steel research international, EarlyView.The use of green recycled steels is constantly expanding in the automotive industry. The increase in tramp elements resulting from the recycling of steel is problematic. Tramp elements can lead to a negative influence on the weldability. To understand the influence, the welding properties of three green steels are characterized. The potential limits of

steel research international, EarlyView.This work investigates the wear resistance and nitriding behavior of PBF‐LB/M‐processed Osprey HWTS 50, a lean hot work tool steel. Three heat treatment conditions are compared to conventional wrought H13, H11, and PBF‐LB/M 18Ni300. The study highlights HWTS 50's enhanced nitrogen diffusion, deeper nitriding hardness depth, and comparable or improved ...
