Liquid Metal Embrittlement (LME) during Resistance Spot Welding (RSW) can cause cracks when welding advanced high strength steels. Recent advances in steel metallurgy, resistance spot welding processing and accompanying simulation tools have substantially improved the way that LME can be handled in industrial practice. This article gives a brief overview of easy measures to implement […] The post Four Steps to Mitigate Liquid Metal Embrittlement When Welding Steel appeared first on AHSS Gui...| AHSS Guidelines
Automakers contemplating whether a part is cold stamped or hot formed must consider numerous ramifications impacting multiple departments. Here, we'll focus on grade options and corrosion protection.| AHSS Guidelines
Steel, and specifically advanced high strength steel, satisfies automotive industry requirements for safety, emissions, fuel efficiency, manufacturability, durability, and affordability. Affordability The automotive industry has adopted light-weighting as a key part of their greenhouse gas reduction strategy. This strategy, however, must be executed in an affordable manner. Key reasons to deploy advanced high strength steels […]| AHSS Guidelines
Manufacturers embrace Advanced High Strength Steels as a cost-effective way to satisfy functional and regulatory requirements. The following are just a few examples where automakers have attributed improved performance and lightweighting due to the use of these advanced steels. KIA EV9 The Kia EV9, Kia’s first three-row electric flagship SUV, is based on the Electric […]| AHSS Guidelines
Our most recent Autonomous vehicle engineering project, Steel E-Motive, was designed to unveil and meet the challenges of future autonomous vehicles.| AHSS Guidelines
Tensile property characterization of mild and high strength low alloy steel (HSLA) traditionally was tested only in the rolling direction and included only yield strength, tensile strength, and total elongation.| AHSS Guidelines
Metal stampers and die shops experienced with mild and HSLA steels often have problems making parts from AHSS grades. The higher initial yield strengths and increased work hardening of these steels can require as much as four times the working loads of mild steel.| AHSS Guidelines
Roll Forming takes a flat sheet or strip and feeds it longitudinally through a mill containing several successive paired roller dies, each of which incrementally bend the strip into the desired final shape. The incremental approach can minimize strain localization and compensate for springback.| AHSS Guidelines
Roll forming is no longer limited to producing simple circular, oval, or rectangular profiles. Advanced cross sections highlight some profile designs that aid in body structure stiffness and packaging space reductions.| AHSS Guidelines
