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.

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 ...
Preheat oven to 225°. Remove the ribs from the fridge and add the lemon-lime soda and orange juice to the roasting pan. For best results, pour the cooking liquid around the ribs and not over top.

Once you’ve removed the roast from the oven, crank the heat up to 550°. When the oven reaches 550°, put the prime rib back in for 7-10 minutes, until the outside has developed a mahogany ...
A delicious steak is always a treat, but before you savor that first juicy bite, there is prep work to be done. Making sure the steaks have been fully thawed and brought to room temperature is the ...
An advantage of the Meyer test is that it is less sensitive to the applied load, especially compared to the Brinell hardness test. For cold worked materials the Meyer hardness is relatively constant and independent of load, whereas for the Brinell hardness test it decreases with higher loads. For annealed materials the Meyer hardness increases ...
