At Kiyo R&D Center & Laboratory, we specialize in multiple hardness testing methods to cater to different materials and applications. Our state-of-the-art facility in Chennai offers the following key hardness testing techniques:
The Brinell Hardness Test (BHN) is ideal for measuring the hardness of metals and alloys with coarse structures, such as castings and forgings. This test involves pressing a steel or tungsten carbide ball into the material under a fixed load and measuring the indentation. It is widely used in heavy industries where material strength is a critical factor.
The Rockwell Hardness Test In Chennai is one of the most commonly used hardness testing methods, offering quick and direct readings. It measures the depth of penetration of an indenter under a fixed load. With multiple Rockwell scales (HRC, HRB, etc.), this method is suitable for testing both soft and hard metals, including steel, aluminum, and brass.
For precise and micro-scale hardness testing, the Vickers Hardness Test (VHN) is preferred. It utilizes a diamond pyramid-shaped indenter to apply force on the material. This method is particularly effective for thin materials, coatings, and small parts, providing high accuracy and repeatability.
For polymers, elastomers, and rubbers, Shore Hardness Testing is the standard method.
