Precision specimen preparation facility
In-house machine shop encompasses clean, temperature controlled environment and state of the art equipment including: CNC lathes, wire EDMs, surface grinder, and notching low-stress grinders. Our reputation for quality machining and superior engineering experience can make sub-size specimens & Chevron Notch to very close tolerances.
Simulated heat treatment cycles (Hardening, tempering, Solution annealing and ageing) on the specimens are performed.
The Mechanical Testing Labs at MIDHANI test materials in accordance with customer specific specifications as well as all applicable ASTM Standard Test Methods.

Our chemical Lab also employs X-Ray, Atomic Absorption, Optical Emission & Ultra-voilet visible Spectrometry and gas analysis, wet Chemistry. Optical Emission Spectrometry (OES or Arc Spark) for routine analysis of metals and their alloys. The OES has been designed specifically to meet the demands of quality in Iron, Cobalt, Titanium and Nickel-based alloys (ASTM E353).
Carbon, Sulfur, Hydrogen, Oxygen, and Nitrogen content in steel and titanium is determined by the inert gas fusion thermal conductivity method (ASTM E1019 and ASTM E1447) utilizing Leco instrumentation.
Chemical compositional analysis is also carried out using X-ray Fluorescence Spectrometry, PMI, semi-quantitative analysis using Mobile Optical Emission Spectrometry.
