Global Export Of Din 1 2379 Mold Steel Flaw Detection And Inspection - China

For DIN 1.2379 mold steel (high carbon, high chromium cold work die steel), flaw detection primarily uses ultrasonic testing (UT), supplemented by magnetic particle (MT) and penetrant (PT) testing, based on DIN EN 10228-3 and YB/T 6019-2022 - Detection Methods and Applicable Scenarios 1 - Ultrasonic Testing (UT, Required) Detection Object: Internal defects (inclusions, porosity, shrinkage cavities, cracks, white spots) Probe and Frequency - Thickness < 50 mm: Dual-crystal straight probe, 2–5 MHz (high resolution near surface) - Thickness 50–200 mm: Single-crystal straight probe, 2–2.5 MHz - Thickness > 200 mm: Single-crystal straight probe, 1–2 MHz (penetration priority) - Scanning Requirements - Sound beam perpendicular to metal flow lines/forging direction - 100% coverage, overlap ≥ 15%; manual speed ≤ 150 mm/s - Plane: Grid scan; Round bar: Circumferential + axial scan - Sensitivity Calibration - Use a comparison test block of the same material (flat-bottomed hole Φ2/Φ3/Φ4 mm) to create a **DAC curve** - Alarm threshold: Adjust the echo from the maximum depth flat-bottomed hole to 80% of the screen height, then raise it again during scanning.

dB** In summary, DIN 1.2379 mold steel flaw detection uses UT (DIN EN 10228-3) as the core, supplemented by MT/PT, and is performed after heat treatment, focusing on controlling cracks, white spots, and large inclusions.

Strict adherence to standard procedures and acceptance levels can effectively ensure the internal and surface quality of mold steel.
