Understanding the mechanical properties of steel

When it comes to steel, the mechanical properties of the grade of steel can often mean the difference between a long, efficient life and frequent or even catastrophic failure in the most abrasive and wear-intensive applications. Understanding these properties is critical when deciding on the best abrasive-resistant steel grade for your application. Unfortunately, these mechanical properties are quite specific, and their precise metallurgical definitions are not widely known outside of the field of metallurgy.

Steel has a variety of properties such as tensile strength, hardness, toughness, fatigue strength, and so on. Materials are frequently chosen for a variety of applications because they have desirable mechanical properties. Material properties are critical in structural applications, and engineers must consider them. Here are some of the properties of steel:

  1. Yield Strength: The yield strength of a material is the point at which the rate of strain in relation to stress begins to increase significantly. At this point, ductile materials like low carbon steel will begin to deform significantly.
  2. Tensile Strength: A material’s tensile or ultimate stress is the point at which deflection will continue until fracture unless the load is reduced. In other words, this is the amount of stress that, given enough time, will cause a material to fail. When approaching a material’s tensile strength, you must either add reinforcement, increase the cross-sectional area, switch to a higher strength material, or reduce the load.
  3. Elongation: Elongation is the amount a material will stretch in comparison to its initial state prior to fracturing. This is expressed as a percentage of total elongation divided by starting length. The greater the brittleness of a material, the less it will elongate before fracturing. 
  4. Hardness: A material’s hardness indicates how well it will resist local plastic deformation caused by mechanical indentation or abrasion. During the manufacturing process, hardness is especially important. Materials with high hardness cannot be machined or formed in the same way that materials with a lower hardness can.
