In order to ensure metal meets a certain requirement for its intended purpose, metal hardness testing must be done. At Paulo, we use three different methods of metal hardness testing—Rockwell, Brinell, and microhardness—to determine if the metal meets our customer’s specifications. 

Ryan Van Dyke, one of our metallurgists, dives into these three methods. He shares what each test is, how they’re performed, and what calls for each test in this installment of Paulo’s Metallurgy Minute.

You can learn more about this topic in our technical article covering the differences between Rockwell, Brinell, and microhardness testing.
