JIS G 3134 SPFH590 plate mainly used for Automobile frames, Refer SPFH590 Steel Equivalent Material

This material is primarily used for automobile frames as it has high strength properties which gives strength to structural design and load-bearing capability. Its high strength helps to design lower-weight frames without losing the structural strength so overall the weight of the material will be less but strength will be higher. This makes it easy for the consumer who wants to make difficult frames designs for their applications.

DIN 1.0980 material have upto 0.5% silicon, Check Physical Properties of HR50F45

As you know, the modulus of elasticity refers to the material capability to resist damage under pressure by evaluating its hardness quality. And specific thermal capacity is the ratio of heat absorbed per unit mass of the material when its temperature rises to 1⁰C and its unit is called as J/(kg ⁰C).

Hence it is important for the engineers in order to ensure the precise load and stress of the material which it can bear, for safe structural designs, avoidance of early material and component failure.

Check Heat Treatment of SPFH590 JIS G3134 material

The below give are the list of testing which are preferable to check the quality of SPFH590 material. Which can help you to decide which testing will be perfect to get the conclusion of your desired application.

  • Impact test is done to check toughness at different temperatures
  • Hardness test is done to check the wear resistance and surface strength
  • Tensile test is done to check the capacity to resist stretching forces
  • Flexure test is done to check bending of flexing which will give an idea of how much load it can bear without getting cracked
  • Deformation test is done to check the material ability to go through flexible deformation without failure
  • Fatigue and Fracture Mechanics Tests are done to check the structural integrity. It gives you a picture of crack initiation, crack growth and crack instability.
