Resistance of Material Against Localized Plastic Deformation

The quick and versatile mechanical property evaluation can be made through its hardness testing, typically measures the resistance of material against the localized plastic deformation.

It serves the basics for real engineering metallurgical process development as well the product quality control. Depending on the product/material type, configuration and intended application will help to choose the hardness scale/type among the others.

EILAB CAPABILITY FOR HARDNESS TEST

EILAB having inhouse capabilities for Vickers hardness testing, Rockwell hardness testing as well capable of equivalent Brinell hardness testing.

We also provide field hardness evaluation by portable hardness test equipment for asset integrity assessment assignments on request to access the material susceptibility to cracking under intended exposed environmental conditions, as well to predict the microstructural changes/degradation for critical engineering equipment.

The test standards as described below

• ASTM E92 : Standard Test Methods for Vickers Hardness and Knoop Hardness of Metallic Materials
• ASTM E384 : Standard Test Method for Micro-indentation Hardness of Materials
