WebOct 23, 2001 · Grade 304 is a standard "18/8" stainless. It is the most versatile and most widely used stainless steel available, even though a wide range of alternatives are available; and has excellent forming and welding characteristics. The balanced austenitic structure of Grade 304 enables it to be severely deep drawn without intermediate annealing. WebJul 28, 2024 · A relatively light, 15 kgf load is applied to case hardened parts treated to achieve a minimum effective case depth 0.007 inches or a total case of 0.012 inches. Other Rockwell variants (HR30N and HR45N) apply slightly higher loads on parts with incrementally higher minimum effective or total cases.

WebIt has a wide range of hardness measurements. It is suitable for measuring the hardness of both ferrous and non-ferrous metals. Its spherical indenter makes the Brinell test more accurate than the Rockwell testing method, as it evenly distributes the load on the material surface. Disadvantages: The typical test uses a 10 mm (0.39 in) diameter steel ball as an indenter with a 3,000 kgf (29.42 kN; 6,614 lbf) force. For softer materials, a smaller force is used; for harder materials, a tungsten carbide ball is substituted for the steel ball. The indentation is measured and hardness calculated as: where:

WebMay 28, 2024 · Hardness allows the metal to resist being permanently deformed when a load is applied. The harder the material is, the greater the resistance it has to deformation, which means the less likely it is to deform.
