Chemical Composition Testing
What Is It
Know Exactly What Metal You’re Working With
Two pieces of steel can look identical and still be completely different grades.
IRC Engineering’s chemical testing verifies the exact elemental composition of ferrous and non-ferrous metals, confirming that the material supplied matches the specified grade.
Supports testing of:
- Carbon & Alloy Steels
- Stainless Steels
- Aluminium
- Copper
- Nickel & Other Alloys
Why Chemistry Matters
Chemistry Determines Everything Downstream
Material chemistry directly affects strength, corrosion resistance, weldability, and high-temperature performance. A small grade mismatch can compromise the mechanical assumptions made for a component.
Grade Verification
Confirms the material matches the specified standard.
Composition Accuracy
Identifies the precise elemental composition.
Failure Prevention
Helps detect chemistry-related material mismatches before they become problems.
Engineering Confidence
Provides reliable data for fabrication and engineering decisions.
How We Test
Our Chemical Testing Method
We use Spectro Analysis to accurately determine elemental composition.
Sample Preparation
The material is prepared for chemical analysis.
Spectro Analysis
The sample is analysed to determine its elemental composition.
Grade Verification
Results are compared with the required material specification.
Deviation Identification
Any chemistry variation or grade mismatch is identified.
Test Reporting
Clear test results are provided for engineering and quality records.
Applications
When Chemical Testing Matters
Pre-Fabrication Verification
Confirm incoming material matches its certification before fabrication or welding.
In-Service Confirmation
Verify that components in operating plants match the specified grade.
Failure Investigation
Identify chemistry mismatches that may contribute to corrosion or mechanical failure.
Weld Procedure Qualification
Verify base metal and filler chemistry during PQR development.
