EN 10028-6 P355QL1 Material Machining Technology
The cost of machining EN 10028-6 P355QL1 steel depends on the type of steel, the complexity of the machining process, the number of parts, and the required tolerances. Generally, manual machining is more expensive than CNC machining because of the need for more human labor hours. Additionally, the cost of machining EN 10028-6 P355QL1 steel is influenced by the cutting tools used. For example, high-speed steel (HSS) tools are cheaper and can be used to quickly produce parts at a lower cost, but they are also less durable and have a shorter lifespan. On the other hand, carbide tools are expensive, but they offer greater durability and can create complex parts with finer details at a higher accuracy.
