Why S550QL EN 10025-6 high strength steel quality is so important

VL E460 steel: is a structural steel plate for ships and offshore engineering."VL" stands for the abbreviation of "DNVGL", which is a standard certified by the two classification societies of DNV (Norway) and GL (Germany). The yield strength is 460. Different classification society certifications, different grade requirements and different yield strengths can be selected according to different needs.

In the manufacturing process of boiler pressure components, raw materials must undergo complex processing deformation and welding, so the steel used to manufacture the boiler must also have good process performance. All materials S550QL EN 10025-6 high strength steel used to manufacture pressure parts must conform to the relevant national standards for boiler steel. The defects such as delamination, non-metallic inclusion, porosity and looseness in the steel shall be as few as possible, and white spots and cracks are not allowed.

No. 45 steel is commonly used medium carbon quenched and tempered structural steel. The cold plasticity of No. 45 steel is generally better than S550QL EN 10025-6 high strength steel. Annealing and normalizing are better than quenching and tempering. No. 45 steel has higher strength and better machinability than Q345 steel. After proper heat treatment, it can obtain certain toughness, plasticity and wear resistance. No. 45 steel S550QL EN 10025-6 high strength steel is suitable for hydrogen welding and argon arc welding, but not suitable for gas welding. Preheating is required before welding, and stress relief annealing shall be conducted after welding.

Our company has strict quality control standards. If you want to visit our factory, you are welcome at any time! We produce a lot of steel products every month to export S550QL EN 10025-6 high strength steel to all over the world.
