Quality Assurance & Testing
Every batch of stainless steel round bars undergoes stringent metallurgical tests to assure compliance with mechanical and dimensional standards before supply. Mill Test Certificates (MTC) conforming to EN 10204 3.1 are provided.
- Ultrasonic Testing (UT): NDT testing to identify any internal defects, voids, or micro-cracks inside forged/rolled bars.
- Chemical Composition PMI: Positive Material Identification to verify exact nickel, chromium, and molybdenum percentages.
- Mechanical Properties Test: Verification of Yield Strength, Tensile Strength, Elongation, and Brinell/Rockwell Hardness.
- Dimensional Precision Check: Tolerance verification (using micrometers) to guarantee alignment with target tolerances (e.g. h9/h11).
- Macro & Micro Structure Test: Evaluates grain boundaries and cleanliness of the steel.
- Third-Party Inspection (TPI): Support for external inspections by agencies like SGS, TUV, DNV, Lloyds, and BV.
