STEEL SPECIFICATIONS

What is steel?

Steel is an alloy of iron and carbon, with small amounts of other elements. The specific composition of a particular steel grade is defined by a standard that specifies the percentage of each element in the alloy. The properties of steel, such as strength, ductility, and corrosion resistance, depend on the specific chemical composition and manufacturing processes used to produce the steel.

There are many different types of steel, each with its own specific set of properties and characteristics. Some common specifications for steel include:

  • Carbon content: The amount of carbon in the steel determines its strength and hardness. Low-carbon steels have less than 0.3% carbon, while high-carbon steels have more than 0.6% carbon.
  • Alloying elements: The addition of other elements, such as manganese, chromium, and vanadium, can improve the properties of steel. For example, chromium can improve corrosion resistance, while vanadium can increase strength and toughness.
  • Heat treatment: The process of heating and cooling steel can change its microstructure and properties. For example, quenching and tempering can increase the strength and toughness of steel.
  • Strength: The strength of steel is typically measured in terms of its yield strength, which is the amount of stress it can withstand before it begins to deform permanently.
  • Ductility: Ductility is a measure of a material’s ability to deform under stress. Steel with high ductility is more likely to stretch or bend without breaking.
  • Corrosion resistance: The corrosion resistance of steel depends on the presence of protective coatings, such as paint or galvanization, as well as the composition of the steel itself. Some steels, such as stainless steel, are more resistant to corrosion than others.

There are many other factors that can affect the properties of steel, including the manufacturing process and the specific application in which it will be used.

Steel has been around since the Bronze age.
