STEELS RAEX 500 PRESENTATION Steel Raex 500 is a steel associating highest hardnesses with implementation an easy. It resists very strong wears by abrasion and impacts. Resulting from recent and modern rolling mills allowing a quenching water fast and controlled, steel Raex 500 has a great purity and a perfect dimensional stability. It replaces the traditional structural steels advantageously, making it possible to reduce the costs of maintenance to a significant degree. Its qualities of abrasive resistant are approximately 6 times higher than a steel S 235 JR. In spite of its high mechanical strength and its raised hardness, steel Raex 500 presents good aptitudes for cutting, working, drilling and welding. It can be delivered in thicknesses of 4 to 60mm.

Placement of steels RAEX • Placement of steel Raex
• Control Documents
In spite of their high mechanical strength and their raised hardness, RAEX Steels present a good weldability and a good aptitude for working.
On request of the customers, we provide for our Raex Steels, a standard statement of control 2.2 or one certificate of reception 3.1 in conformity with the standard EN 10204. On the control documents, are reproduced the chemical composition of steel like its hardness.
• Designation of the grade of steel
Raex 400, Raex 450, Raex 500 Brinell Hardness average : 400 HBW, 450 HBW, 500 HBW Chimical and mechanical characteristics, see tables 1 and 2.

Hardness HBW of steel is given according to the standard EN ISO 6505-1.
• Skin- and flatness (Dead Flat pro-cess)
- The surface hardness of the upper edges of the die groove must be greater than the hardness of the plate that is to be bent. In the structure shown in the figure, the upper edge of the die groove is equipped with 20 mm iron rods with the hardness of approximately 53 HRC. - The grooves in which the iron rods are located must be kept clean. - Widening the die groove decreases the need for bending force but increases springback. - Springback: Raex 400 9° – 13° Raex 500 10° – 15°
Rolling skin- of the coils, known as “Dead Flat process“ (DF), causes a work hardening of the metal which erases the stage of elactic limit of steels and fixes the mechanical characteristics. This rolling of completion eliminates the residual stresses and allows the production of sheets having an excellent flatness. It facilitates the control of the deformations after welding and is appropriate very well for the series production of folded parts. The rolling skin- avoids the planing of the parts cut out in steels DF. It also improves the surface quality of the film them Raex and reduces the geometrical irregularities of surfaces (roughness). Our products make it possible to simplify the cycles of production This process DF is systematically specified on the certificate machines. 2
