GB/T 16270 Q960F Material Machining Technology
The compatibility of tools with GB/T 16270 Q960F steel is important in order to achieve optimal results during machining operations. The tools should have high wear resistance and be hard enough to cut through the steel without wearing out. High-speed steel, cobalt, and tungsten carbide tools are generally recommended as they are hard enough to cut through steel and also have high wear resistance. Carbide and ceramic tools are also recommended for turning operations as they can improve surface finish.
