DILLIMAX 690 is a high strength quenched and tempered, fine grained structural steel with a minimum yield strength of 690 MPa (100 ksi)* in its delivery condition (referring to the lowest thickness range).
Its mechanical properties are achieved by water quenching followed by tempering.

DILLIMAX 690 is preferentially used for welded steel structures within mechanical constructions, plant constructions and structural steel works, such as machines for structural engineering, conveying plants, hoists, cranes, flood gates, bridges and frameworks.
