Ramco Steels Senior Lab Technician Interview Questions and Answers

Hardness processing involves measuring the resistance of a material to indentation or scratching.

• Rockwell hardness test measures the depth of penetration of an indenter under a large load compared to a small load

• HRC measures the hardness of steel and other hard materials

• BHN measures the hardness of materials through the indentation of a ball

• HRA measures the hardness of materials with a diamond cone indenter

• HRB measures...read more

Hardness is the measure of a material's resistance to deformation or scratching.

• It is often measured using the Mohs scale or the Vickers hardness test.

• Hardness can be affected by factors such as temperature and pressure.

• Materials with high hardness include diamond, quartz, and tungsten carbide.

• Hardness is important in many industries, including manufacturing and construction.

Hardness is the resistance of a material to deformation, micro refers to small scale measurements, and sample testing is the process of analyzing a small portion of a larger material.

• Hardness is measured using various methods such as Brinell, Rockwell, and Vickers tests.

• Micro measurements are typically done using microscopes and can refer to things like microorganisms or microstructures.

• Sample testing can involve destr...read more
