Size: 05mm~ 30mm x 1500mm ~12000mm.

Domex 700 MC IS Hot rolled, extra high strength, cold forming steel from SSAB Sweden. Domex cold forming steels are thermo-mechanically rolled in modern plants where the heating, rolling and cooling processes are carefully controlled. The chemical analysis, consisting of low levels of carbon and manganese has precise addition of grain refiners such as niobium, titanium or vanadium. This together with a clean structure, makes Domex Steels the most competitive alternative for cold formed and welded products.

Domex 700 MC with designation D and E meet and exceed the demands for steel S700MC in EN-10149-2.

APPLICATION

The extra high strength steel grades are used in applications such as truck chassis, cranes and earthmoving machines. In these applications, the high strength of the steels is used to save weight and/or to increase the payload. As a result of this and the good formability of the steels, the total costs can be reduced.

Size: 05mm~ 30mm x 1500mm ~12000mm

WEL-TEN series is high tensile & superior weldability steel featuring a rich variety of product categories.

In accordance with the technical evolution, structures or pressure vessels are becoming bigger, and more highly pressurized recently. To maintain the safety of those structures, consequently, customers have required high strength steel plates with good weldability and high toughness. To meet the rapidly growing customer requirements, JFE Steel has developed wide range of high tensile strength steel plates such as 590~980N/mm2 class, with their own special characteristics. These are called JFE-HITEN, and JFE Steel wins a popularity in the world 

High Strength -- JFE-HITEN is low-alloyed high-strength steel plate manufactured by TMCP, or quenched and tempered. Because JFE-HITEN offer high strength, it results in a significant reduction in the weight of welded structures.

Good Weldability -- JFE-HITEN, of which chemical composition is controlled by specific procedure, offers low carbon equivalent and excellent weldability. JFE Steel also supplies welding materials suitable for JFE-HITEN effectively, and thereby enjoys acceptances by customers.

Excellent Notch Toughness -- JFE-HITEN offers high notch toughness because it is produced by closely controlling the chemical composition and heat treatment conditions. Application of JFE-HITEN ensures construction of structures providing high reliability against brittle fracture.

Excellent Uniformity and Clean Surface -- Rolled on the most modern plate mill under rigid quality control, JFE-HITEN has excellent uniformity in properties, flatness and surface finish. In addition, slab surfaces are carefully scarfed, powerful water jets are used during rolling, and non-oxidizing atmosphere furnaces are used for heat treatment. Consequently, JFE-HITEN has smooth, and clean surfaces.

Good Workability -- Because JFE-HITEN features good ductility, it offers not only good formability, but also good machinability, making it easy to drill and cut. 

Wide Range of Sizes -- JFE-HITEN are available in widths of up to 5,350mm, and in lengths of up to 27,000mm, and then contributes to saving expenses
