Quality Control
Steel Quality Control

    To specify the various physical and mechanical properties of the finished product, various tests, both destructive and nondestructive, are performed. Metallurgical, hardness, hardenability, tension, ductility, compression, fatigue, impact, wear, corrosion, creep, machinability, radiography, magnetic particle, ultrasonic, and eddy current are some of the major tests that are performed by quality control personnel.

  • Thickness Test
    By using the theory of electromagnetic field to flow into the steel substrate The size of the magnetic flux to determine the coating thickness
  • Stretching test
    Determination of width, before and after coating removal difference to measure the thickness of the coating thickness
  • Gloss Meter
    Measured relative light reflection mirror coating can be measured samples gloss
  • Zinc Coated Test
    The firmness of the zinc layer is the adhesion between the galvanized layer and the steel substrate The require
  • Bending Machine
    The sample was bent 180 degree around itself, observing bending of the coating cracks or fall off, determining coating cloth cracking or peeling
  • Tensile and Yield strength Test
    To evaluate a catsuit coating and substrate adhesion or ability to resist the separation between multilevel coating layer in the system
  • Color Coating Adhesive Force Test
    In the paint and coating industries, paint adhesion testing is often used to determine if the paint or coating will adhere properly to the substrates to which they are applied
  • Hardness Testing
    Steel hardness describes the properties of steel that enable it to resist plastic deformation, indentation, penetration, and scratching
