Why use high edge ductility HSLA steel?

Compared to conventional HSLA steels, high edge ductility steels have greatly improved local formability and high hole expansion ratios, helping you solve component defects like cracked outer edges and micro cracks on stretched punched holes.

Where is high edge ductility HSLA steel used?

High edge ductility steels are recommended as an alternative to corresponding HSLA grades when there is a need for improved edge ductility. Suspension systems Beams and cross members Wheels Chassis

What is the formability of high edge ductility HSLA steels?

Ideal for fineblanking – opening up HSLA to new, complex designs and new component applications. Enables multiple, complex, crack-free forming operations along sheared stretched edges. Hole expansion ratios 30% better than conventional HSLA. Bend radius of 0.0 xt can be guaranteed.

High edge (HE) ductility HSLA steel

High edge ductility HSLA steel with greatly improved local formability and high hole expansion ratios – ideal for challenging auto components with complex designs on sheared stretched edges.

What is the definition of high edge ductility steels?

Unlike conventional HSLA steels, high edge ductility steels have a much finer microstructure and perlite distribution. This microstructure provides for higher formability, tighter radii bending, and crack-free sheared cuts – even on stretched edges. HE steel’s advanced microstructure is achieved by using exceptionally clean and closely controlled steelmaking processes. The high edge steel also has a low alloy content, making welding straightforward using conventional processes.
