DILLIMAX 500 Tough (EN 1.8924)

DILLIMAX 500 Tough (EN 1.8924) introduction

DILLIMAX 500 is a high strength quenched and tempered, fine grained structural steel (fine grained through sufficient aluminium content.) with a minimum yield strength of 500 MPa (72 ksi) in its delivery condition (referring to the lowest thickness range). Its mechanical properties are achieved by water quenching followed by tempering.
