Using Martensitic Steels as an Alternative to Press Hardening Steel – Laboratory Evaluations
Our colleagues at JFE Steel recently provided us with a new case study based on laboratory evaluations they conducted in Japan. The article is part of our Martensite article, but we this month, we want to highlight it in our AHSS Insights blog. Martensitic steel...
What are 3rd Gen AHSS?
One of the tasks we took great care in completing during the update of the AHSS Application Guidelines was to provide a definition for what constitutes a third generation (3rd Gen) Advanced High-Strength Steel. We had been asked this question many times, and often in...
Conventional Rule-of-Thumb Calculations Lead to Inaccurate Press Tonnage Predictions
The rule of thumb estimates used in 1989 during my internship with an automotive stamping supplier were simple calculations for the peak load. Tonnage for trim and pierce operations depended on the length of line of trim, material thickness and the shear strength of...
Servo Press Force and Energy Considerations When Working With AHSS
Advanced High-Strength Steel (AHSS) products have significantly different forming characteristics and these challenge conventional mechanical and hydraulic presses. Some examples include the dramatically higher strength of these new steels resulting in higher forming...
A New Global Formability Diagram
Bubble chart. Banana diagram. Steel strength ductility diagram—it’s been called a lot of things over the years. But the 2017 chart shown in Figure 1 is the subject of hundreds of requests for use we receive from engineers and students all over the world and appears in...
Additive Manufacturing
Additive Manufacturing (AM) has been associated with the future of manufacturing since its inception. While it does hold several advantages in complex geometries and low-volume production, modern AM systems have yet to make significant in-roads with direct-print parts...
