SUPRALSIM 690 Plates

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

SUPRALSIM 690 is a high strength quenched & tempered steel dedicated for structure and enables to make weight savings thanks to minimum yield strength of 690 N/mm². Thanks to its exceptional purity rate (very low sulphurand phosphorous contents), and its adapted chemical analysis, the SUPRALSIM 690 steel is easy to shape and to weld.

STANDARD

SUPRALSIM 690 fulfills the requirements of S690 QL according to EN 10137-2 standard.

Weight saving and/or more resistant structures
Due to its high yield strength compared to classical steel (750 Mpa in average), you can :- reduce thickness of structure and make weight saving and/or
support higher stresses and realise more resistant structures
