DILLIMAX 690T Plates

High strength fine grained structural steel Quenched and tempered.

Champak Industries' is a specialist supplier and exporter of High strength steels DILLIMAX 690T Plates. We understand customers whose requirement for High strength steels Plates is extreme and who cannot use inferior quality steel plates.

DILLIMAX 690 is a high strength quenched and tempered, fine grained structural steel with a minimum yield strength of 690 MPa (100 ksi)2 in its delivery condition (referring to the lowest thickness range). 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.

DILLIMAX 690 CAN BE DELIVERED IN THREE QUALITIES AS FOLLOWS:

Basic (B) with minimum impact values at 20 °C (-4 °F)2 : DILLIMAX 690 B Material No. 1.8931 - S690Q according to EN 10025-6

Tough (T) with minimum impact values at 40 °C (-40 °F)2 : DILLIMAX 690 T Material No. 1.8928 - S690QL according to EN 10025-6

Extra tough (E) with minimum impact values at 60 °C (-76 °F)2 : DILLIMAX 690 E Material No. 1.8988 - S690QL1 according to EN 10025-6 DILLIMAX 690 can be delivered as basic grade (B) or tough grade (T) in thicknesses from 6 to 255 mm (¼ to 10 in.)2 , as extra tough grade (E) in thicknesses from 6 to 200 mm (¼ to 8 in.)2 according to the dimensional program. DILLIMAX 690 fulfills all requirements of EN 10025-6. If a CE marking according to EN 10025-1 is needed, an additional attestation for the corresponding quality according to EN 10025-6 has to be ordered.
