Steel Hardness versus Strength; Brinell While mild steel has a lower tensile strength than other carbon steel types, it is more pliable and easier to form. You can also harden mild steel with various treatment processes. Mild steel is machinable and weldable, which aids in its usefulness for most applications. Common uses of mild steel include: Building construction; Pipelines
The Brinell hardness HBW results from the quotient of the applied test force F (in newtons N) and the surface area of the residual indentation on the specimen (the projection of the indentation) after removal of the test force (see Brinell formula).To calculate the surface area of the residual ball indentation, the arithmetic mean d of the two perpendicular diagonals d1 and d2 (in mm) is .
The surface hardness of mild steel can be increased through heat treatment processes like carburizing. This material has moderate strength but as it is cheap and easy to shape, hence, most of the products are of mild steel. Material testing is necessary to determine its mechanical properties and behaviour.
In the Rockwell hardness test, a differential-depth method, the residual depth of the indent made by the indenter, is measured.In contrast, the size of the indentation is measured in the Brinell, Vickers and Knoop optical test methods.. The deeper a defined indenter penetrates the surface of a specimen with a specified test load, the softer the material that is being tested.The Brinell hardness test is used for hardness testing larger samples in materials with a coarse or inhomogeneous grain structure. The Brinell hardness test (HBW) indentation leaves a relatively large impression, using a tungsten carbide ball. The size of the indent is read optically. Used for materials with a coarse or inhomogeneous grain .

Rockwell hardness test is one of the most common indentation hardness tests, that has been developed for hardness testing. In contrast to Brinell test, the Rockwell tester measures the depth of . The Brinell hardness test measures material hardness by determining the diameter of an indentation made by a hardened steel or carbide ball under a specific load. A load, typically ranging from 500 to 3,000 kgf, is applied to the material’s surface for 10-15 seconds, allowing the ball to penetrate and create an indentation.
