Charpy Impact Testing

Applicable materials: Suitable for various metal materials and welding joints such as carbon steel, alloy steel, stainless steel, duplex stainless steel, cast iron, nickel based alloys, aluminum alloys, copper alloys, titanium alloys, etc.

Applicable objects: including plates, bars, pipes, profiles, forgings, castings, structural components, pressure vessels, pipelines, engineering components and welding joints, heat affected zones, base materials and other welding joint zones.

Applicable scenarios: Used for raw material inspection, heat treatment quality assessment, welding process validation, impact toughness evaluation, low-temperature brittle fracture resistance testing, ductile brittle transition characteristic analysis, product mechanical performance acceptance, and failure analysis.

Charpy impact absorption energy measurement: V-notch impact energy (KV) and U-notch impact energy (KU) testing.

Calculation of Impact Resilience Value: Calculation of Unit Section Impact Absorption Energy.

Low temperature Charpy impact test: impact performance testing at different low temperatures.

Determination of ductile brittle transition temperature: Determine the critical transition temperature between ductile fracture and brittle fracture of materials.

Impact fracture morphology analysis: Determine whether the fracture type is ductile fracture or brittle fracture.

Partition impact testing of welded joints: testing the Charpy impact toughness of the base metal, weld seam, and heat affected zone separately.

Qualification assessment of impact performance: Determine whether it meets the usage requirements by comparing it with the standards and technical requirements.
