ASTM A131/A131M A131 Grade FH32 Material Machining Technology
For most metal machining operations, the most common types of tools are carbide, high-speed steel (HSS), and cobalt. Carbide and HSS tools are the most popular choice, as they tend to be strong, durable, and able to withstand high temperatures. Cobalt tools, while costlier and more difficult to maintain, are most suitable for highly abrasive materials and heavy-duty machining operations.
