A variety of hardness-testing methods are available, including the Vickers, Brinell, Rockwell, Meyer and Leeb tests. Although it is impossible in many cases to give an exact conversion, it is possible to give an approximate material-specific comparison table for steels.
number symbol name Mohs hardness [1] Vickers hardness (MPa) [1] Brinell hardness (MPa) [1] Brinell hardness (MPa) [note 1] [2] 3: Li: lithium: 0.6: 5: 4: Be: beryllium: 5.5: 1670: 590–1320: 5: B: boron
Brinell hardness is sometimes quoted in megapascals; the Brinell hardness number is multiplied by the acceleration due to gravity, 9.80665 m/s 2, to convert it to megapascals. The Brinell hardness number can be correlated with the ultimate tensile strength (UTS), although the relationship is dependent on the material, and therefore determined ...
A thick slice of beef tenderloin A section of braised tenderloin of beef that has been seared in a heavy skillet on all 4 sides until lightly browned, about 3 to 4 minutes each. As with all quadrupeds, the tenderloin refers to the psoas major muscle ventral to the transverse processes of the lumbar vertebrae, near the kidneys. [2]
A Rockwell hardness tester. The Rockwell hardness test is a hardness test based on indentation hardness of a material. The Rockwell test measures the depth of penetration of an indenter under a large load (major load) compared to the penetration made by a preload (minor load). [1]
Yields: 8-10 servings. Prep Time: 20 mins. Total Time: 1 hour 5 mins. Ingredients. BEEF. 1 (4 to 5 pound) whole beef tenderloin, trimmed. 2 tsp. kosher salt

2. Using a sharp paring knife, make 1-inch slits all over the tenderloin steaks. Stuff the slits with the garlic chips. 3. Fill a large, sturdy, resealable plastic freezer bag with the shallots, rosemary, thyme, lime leaves, orange zest, fish sauce, soy sauce, dried chiles and the reserved garlic oil.
