Metal Sheet Inspection

Applicable materials: Suitable for various metal plates and steel strips such as carbon steel, low-alloy steel, alloy steel, stainless steel, heat-resistant steel, aluminum alloy, copper alloy, titanium alloy, etc.

Applicable products: including hot-rolled plates, cold-rolled plates, medium thick plates, thin plates, patterned plates, boiler plates, container plates, structural plates, stamped plates, pickled plates, and various types of metal plates and strips.

Applicable scenarios: Used for raw material incoming inspection, factory quality acceptance, stamping and forming process evaluation, engineering component acceptance, in-service testing, failure analysis, and quality arbitration testing.

Chemical composition analysis: determination of carbon, silicon, manganese, sulfur, phosphorus, chromium, nickel, molybdenum, titanium, vanadium and other elements, determination of conformity between grades and compositions.
Mechanical performance testing: room temperature tensile, yield strength, tensile strength, elongation at break, impact toughness, Rockwell/Brinell/Vickers hardness, cold bending performance testing.
Performance testing of forming process: cupping test, hole expansion test, bending test, tensile strain hardening index n value, plastic strain ratio r value, forming limit diagram testing.
Metallographic examination: microstructure, grain size, non-metallic inclusions, decarburization layer, banded structure, delamination, segregation inspection.
Non destructive testing: ultrasonic testing, X-ray testing, magnetic particle testing, penetrant testing, used for detecting internal and surface defects.
Dimensional and appearance inspection: evaluation of thickness, width, length, unevenness, sickle bend, side bend, dimensional tolerance, and geometric tolerance.
Surface quality inspection: Evaluation of appearance defects such as surface cracks, folds, scratches, oxide scale, pitting, peeling, color difference, and surface roughness.
Corrosion performance testing: intergranular corrosion, pitting corrosion, uniform corrosion, salt spray corrosion, stress corrosion cracking performance testing.
Failure analysis: Analysis of failure modes and causes such as cracking, rusting, deformation, wear, fatigue, etc. of the sheet metal.
