Material Test Certificate (MTC)
Document certifying the chemical composition and mechanical properties of steel used in manufacturing.
A Material Test Certificate (MTC), also called Mill Test Certificate, is an official document issued by the steel mill certifying the properties of a specific steel batch. It provides traceability from raw material to finished product.
Certificate types (EN 10204):
- **Type 2.1**: Self-declaration by manufacturer
- **Type 2.2**: Test report without specific values
- **Type 3.1**: Inspection certificate with specific test values (most common)
- **Type 3.2**: Third-party inspection certificate
Contents of 3.1 MTC:
- Heat/batch number
- Chemical composition (C, Mn, Si, P, S, etc.)
- Mechanical properties (yield, tensile, elongation)
- Hardness values (for wear steels)
- Impact test results (Charpy)
- Dimensions and mass
- Applicable standards
Why MTCs matter:
- Verify material claims (genuine Hardox, Strenx)
- Enable traceability in case of failure investigation
- Required for many industrial and infrastructure projects
- Insurance and quality management requirements
Sieruta provides EN 10204 3.1 MTCs for all steel components, traceable to original SSAB mill certificates.
