Dogal LAD grades are micro-alloyed cold-forming steels that derive their high strength from the addition of very small quantities of alloying elements. These steel grades are designated according to their lowest guaranteed yield strength. The difference between their yield strength and tensile strength is small. LAD grades have good formability and bendability in relation to their yield strengths.
The consistency of the mechanical properties of Dogal LAD steels is guaranteed within the specified minimum and maximum values. Dogal LAD grades conforms the provisions of EN 10292.
Dogal LAD steels are intended for general presswork, forming and bending operations. These grades can be bent, sheared and punched on standard workshop equipment. Slightly higher forces may be necessary.
Whenever steel sheet parts are pressed and then painted, the work-hardening and bake-hardening properties of Dogal LAD steels can be put to good use. Work-hardening occurs during pressing, and bake-hardening takes place when the paint is being cured, if the curing is done at elevated temperature.
