Metallurgical Testing Laboratory
Material claims are worth nothing without measurement. Our laboratory verifies chemistry by optical emission spectrometry on incoming billets, then confirms mechanical properties and microstructure on the finished forging before release.

Incoming Material Verification
Every heat lot is spectro-tested against the mill certificate before it enters production. Grade substitution — an expensive and recurring problem in the Indian steel supply chain — is caught at the gate rather than discovered on the customer's assembly line.

- Heat-lot segregation and tagging
- Mill certificate cross-verification
- Rejection at gate, not at dispatch
Mechanical Property Testing
Tensile strength, yield, elongation and reduction of area are measured on machined specimens; Charpy impact testing establishes toughness at ambient or sub-zero temperature where the application demands it. Results are reported per batch with the heat number.
Microstructure and Grain Flow
Etched samples are examined for grain size, decarburisation depth, banding and inclusion rating. Macro-etched sections reveal forging grain flow, which is the direct evidence that the die design is delivering the metallurgical benefit the part was forged for.
What the Laboratory Tests, and to Which Standards
Material claims are only as good as the measurements behind them. Our laboratory verifies chemistry on incoming material and mechanical properties and microstructure on finished forgings, so a certificate reflects what was measured rather than what was expected.
| Test | What it establishes | Reference standard |
|---|---|---|
| Optical emission spectrometry | Chemical composition of each heat lot | Per grade specification |
| Tensile test | Tensile, yield, elongation, reduction of area | ASTM E8 / ISO 6892 |
| Charpy impact test | Toughness at ambient or sub-zero temperature | ASTM E23 / ISO 148 |
| Brinell hardness | Core hardness of forged and heat treated parts | ASTM E10 |
| Rockwell hardness | Hardened surfaces and hardened parts | ASTM E18 |
| Microstructure examination | Grain size, decarburisation, banding, inclusions | ASTM E112 for grain size |
| Macroetch | Grain flow and internal soundness | ASTM E381 |
| Case depth | Effective depth on hardened surfaces | ISO 2639 and equivalents |
Catching Grade Substitution at the Gate
Grade substitution is a persistent and expensive problem in low-cost steel supply chains, and the only reliable defence is testing the material rather than reading its paperwork. Every heat lot is spectro tested against its mill certificate before it is released to the shop floor, and lots are physically segregated by heat number. The cost of catching a wrong grade at the gate is a rejected delivery; the cost of discovering it on a customer's assembly line is very much higher. See how to read a material test certificate.
Testing as a Standalone Service
Laboratory testing is also offered independently of forging, on customer-supplied material or components, with a written scope and a signed report. Typical requests include verifying the grade of an unknown part before reverse engineering it, establishing why a component failed, and confirming hardness and case depth on parts heat treated elsewhere. Reports state method, equipment, result and traceability data.
- Grade identification on unknown or obsolete parts
- Failure investigation with microstructure and macroetch
- Hardness and case depth verification
- EN 10204 3.1 material certificates on request
