HIGH YIELD STRUCTURAL STEEL PLATES
NAXTRA 70 Plates is a high yield structural steel or High strength steels grade produced in compliance with EN 10025:6:2004. The material is heats treated using the quench and temper process and has good bending and welding properties
The code "S" for steel grade S690QL means structural steel.
The code "Q"refers to the delivery condition, in this case to quenched & Tempered.
The code "L" means that the average minimum values for impact energy have been defined at a temperature of -40°C.
Due to the materials high strength nature, using S690QL will promote leaner designed structures with increased payload capacity and energy efficiency.
