  • 2025-02-20 11:41:24

Technical Breakdown: The Science Behind Steel Elongation Tests

  1. Test Parameters

    • Measures % elongation at break via controlled tensile loading

    • Critical for determining yield strength (Rp0.2) and ultimate tensile strength (UTS)

    • Required by ASTM E8/E8M, ISO 6892-1, JIS Z2241

  2. ITM-LAB UTM Advantages

    • 0.5% force accuracy (Class 0.5 per ISO 7500-1)

    • 100kN-2000kN capacity options for all steel grades

    • Integrated video extensometers for strain measurement (±1μm resolution)
