Product Introduction

Detection range
Applicable materials: Suitable for metal materials such as carbon steel, alloy steel, stainless steel, duplex stainless steel, cast iron, aluminum alloy, copper alloy, titanium alloy, nickel based alloy, and various welding joints.
Applicable objects: including plates, bars, pipes, profiles, forgings, castings, structural components, engineering parts and welding joints, heat affected zones, base materials and other welding joint areas.
Applicable scenarios: Used for raw material inspection, heat treatment quality assessment, welding process verification, low-temperature brittle fracture resistance evaluation, material toughness brittle transition characteristic analysis, failure analysis, and product mechanical performance acceptance.
Testing items
Charpy impact absorption energy measurement: V-notch impact energy (KV) and U-notch impact energy (KU) tests.
Calculation of Impact Resilience Value: Calculation of Unit Section Impact Absorption Energy.
Low temperature impact testing: testing of impact performance at different low temperatures.
Measurement of ductile brittle transition temperature: Determine the temperature at which a material transitions from ductile fracture to brittle fracture.
Impact fracture morphology analysis: Determine whether the fracture type is ductile fracture or brittle fracture.
Partition impact testing of welded joints: testing the impact toughness of welds, heat affected zones, and base materials separately.
