Analysis of Mechanical Properties of mild steel Applying Various Heat treatment

These efforts were similar and overlapped significantly. The alloy number is simply a general classifier, whereas it is the specification itself that narrows down the steel to a very specific standard. The AISI system uses a letter prefix to denote the steelmaking process. The prefix "C" denotes open-hearth furnace , electric arc furnace or basic oxygen furnace , while "E" denotes electric arc furnace steel. Carbon steels and alloy steels are designated a four digit number, whereby the first digit indicates the main alloying element s , the second digit indicates tg top grade element s , and the last two digits indicate the amount of carbon, in hundredths of a percent basis points by weight. For example, a steel is a plain-carbon steel containing 0.

Mild Steel – All You Need to Know

Steel is a combination of iron and carbon, but did you know there are more than 3, different grades of steel? Steel is graded as a way of classification and is often categorized into four groups —Carbon, Alloy, Stainless, and Tool. Steel grading systems provide a way to categorize steel based on all the different factors that can influence its properties and uses. For instance, the rate steel is cooled can impact how its molecules are joined together, as can the amount of time the steel is held at several critical temperature points during the cooling process. Steel grading standards are widely used by scientists, engineers, architects, and government agencies to ensure quality and consistency of materials. These standards provide a common language to communicate the properties of steel with great specificity, and guide product manufacturers toward proper processing and application procedures. What are the Different Grades of Steel.

Carbon Steel: Properties, Production, Examples and Applications

In essence, steel is composed of iron and carbon, although it is the amount of carbon, as well as the level of impurities and additional alloying elements that determine the properties The precipitation hardening grades show considerably higher hot strengths at lower temper-atures, but their strength advantage disappears quickly as they begin to overage. The features of our products are as indicated below. Mild steel is the alloy of iron and cementite not carbon with latter being in the range of 0.


Steels are widely used materials in the industry. The carbon present in the form of iron-carbide Fe3C increases the hardness and strength of the steel. Based on Method of manufacturing of steels, they are classified as Bessemer steel method and Electric Arc Furnace method whose explanation is below. The principle of Bessemer Converter is the removal of impurities from the iron by oxidation and the air is being blown through the molten iron. The impurities manganese mn and Silicon Si are converted into their respective oxides and that can be expelled out. It is an extremely hot enclosed region, where heat is produced employing electrodes for melting certain materials such as steel scrap without changing the electrochemical properties of the material metal. The electric arc produced between the electrodes and the metal is used for melting the metal scrap.
