Hardness Test

Hardness is the ability of a material to resist harder objects pressing into its surface. Hardness testing is used to determine the materials' resistance against deformation, penetration, scratching, or other physical force.

STEMart can conduct straightforward, timely and cost-effective hardness testing on a variety of materials, and provide basic data for material selection, lot verification, and evaluation of material processing.

Test Capabilities

• Brinell hardness testing: Suitable for soft materials, such as non-ferrous metals, steel before or after heat treatment
• Rockwell hardness testing: Suitable for low to high-hardness materials including steel sheet, cemented carbide, mild steel, non-ferrous metals, annealed steel, quenched steel, cast iron and so on.
• Vickers hardness testing: Suitable for almost all metal materials used in the industry can be measured, from very soft materials (several Vickers hardness units) to very hard materials (3000 Vickers hardness units).
• Knoop hardness testing: Especially suitable for testing hard and brittle materials, often used to test enamel, glass, synthetic diamond, cermet and minerals and other materials.
• Shore hardness testing: Suitable for non-metallic materials such as plastics, rubber and glass.
• Mohs hardness testing: Suitable for hardness measurement of minerals.
• Barcol hardness testing: Suitable for soft materials such as reinforced or non-reinforced rigid plastics.
• VST hardness testing: Determine the softening point of materials that have no definite melting point, such as plastics.
• Hot hardness testing
• Microhardness testing: Suitable for hardness measurement of brittle materials such as glass, ceramics, minerals as well as thin or small materials such as surface coatings and plantings.
• Macrohardness testing: Suitable for quality control of surface treatment processes.

Test Material Types

• Metals
• Ceramics
• Welding
• Polymers
• Adhesives, etc.
