How Rigang Steel Guarantees Quality with Mill Test Certification

In the competitive steel industry, quality assurance is non-negotiable. Rigang Steel, a subsidiary of Rigang Metal Group, employs Mill Test Certification (MTC) as a cornerstone of its quality control framework. This documentation verifies that our steel products—from Duplex Stainless Steel to API 5L Pipe—meet stringent international standards.

What Is Mill Test Certification?

MTC, also known as EN 10204 certification, is a formal record confirming a product's compliance with order specifications. It includes:

• Chemical Composition: Precise alloy percentages (e.g., Carbon, Chromium)
• Mechanical Properties: Tensile strength, yield strength, and elongation
• Dimensional Accuracy: Thickness, width, and length tolerances
• Testing Methods: Charpy impact tests, hardness tests, or hydrostatic tests for pipes

Our certifications validate compliance with diverse industrial requirements:

Why MTC Matters for Global Buyers

For industries like oil & gas or construction, MTC ensures:

1. Traceability: Batch-specific data for recalls or audits
2. Regulatory Compliance: Meets import/export documentation needs
3. Risk Mitigation: Third-party verification (e.g., SGS, TÜV) minimizes defects

Our 4-stage quality assurance protocol:

• Raw Material Inspection: Spectrometer analysis for alloy verification
• In-Process Testing: Real-time monitoring during rolling/casting
• Final Product Testing: Destructive/non-destructive tests per ASTM/EN
