Metal Steel Testing

Applicable materials: Suitable for various types of black metal steels such as carbon steel, low-alloy steel, alloy steel, stainless steel, heat-resistant steel, tool steel, bearing steel, spring steel, cast iron, as well as steel billets and castings.

Applicable products: including plates, bars, pipes, profiles, wires, strips, forgings, castings, welded parts, fasteners, steel structural parts, steel for pressure vessels, steel for pipelines, and steel for engineering structures.

Applicable scenarios: Used for raw material incoming inspection, factory quality acceptance, material conformity determination, mechanical performance evaluation, process validation, non-destructive testing, failure analysis, engineering quality testing, and arbitration testing.

Chemical composition analysis: determination of alloy element content such as carbon, silicon, manganese, sulfur, phosphorus, chromium, nickel, molybdenum, titanium, vanadium, and determination of steel grade.
Mechanical performance testing: room temperature tensile, yield strength, tensile strength, elongation at break, section shrinkage, impact toughness, hardness, bending/repeated bending, fatigue, and high-temperature creep performance testing.
Metallographic examination: microstructure, grain size, non-metallic inclusions, decarburization layer, carburizing layer, banded structure, segregation, white spots, forging and rolling streamline inspection.
Process performance testing: cold bending, expanding, flattening, curling, welding process evaluation, heat treatment process adaptability verification.
Non destructive testing: ultrasonic testing, X-ray testing, magnetic particle testing, penetrant testing, eddy current testing, to detect internal and surface opening defects.
Size and surface inspection: Appearance evaluation of external dimensions, wall thickness, tolerances, form and position tolerances, flatness, ellipticity, surface roughness, rust, scratches, cracks, folds, and pitting.
Corrosion performance testing: intergranular corrosion, pitting corrosion, salt spray corrosion, atmospheric corrosion, stress corrosion cracking performance testing.
Failure analysis: comprehensive analysis of failure modes and causes such as fracture, corrosion, wear, fatigue, etc.
