What is difference between Rockwell and Superfical Rockwell? A fundamental distinction is made between two types of Rockwell method: Regular Rockwell (or Rockwell) and Superficial Rockwell (or Super Rockwell) • Rockwell: The pre force (or preload) is always 10 kgf, while the total test force (also ...
