Description
A structural steel developed for use in demanding load-bearing structures within the Offshore and Marine Industry.
S700 steel exceeds the requirements of S690QL steel, EN 10025-6. S700 steel can be ordered with dual steel grades certificate, where the additional steel grade is defined and approved by one of the Classification Societies listed below.
The dual certification offers You the benefits of excellent mechanical properties, extra tight tolerances, formability and consistency of VANFORGE

Delivery Conditions
The delivery condition is Q+T (Quenched and Tempered). The plates are delivered with sheared or thermally cut edges.
Untrimmed edges after agreement.
Fabrication and Other Recommendations
Welding, bending and machining.
S700 steel has obtained its mechanical properties by quenching and subsequent tempering. The properties of the delivery condition cannot be retained after exposure to temperatures in excess of 580 °C.
Appropriate health and safety precautions must be taken when welding, cutting, grinding or otherwise working on this product. Grinding, especially of primer coated plates, may produce dust with a high particle concentration.
