Email Steel, an alloy of iron, is one of the most versatile and useful metals known to mankind. In this ScienceStruck write-up, we shall learn about some interesting facts and properties of this metal. Steel is an alloy, consisting mainly of iron, with a carbon content of 0. Though the use of carbon is most common for the production of this metal alloy, other alloying materials like tungsten, chromium and manganese are also used.
The proportions and forms in which these elements are used, affect the properties of the steel that is produced — increasing the carbon content for instance, increases its strength. This fact is particularly useful for making different types of steel for different purposes — the strength of steel needed to make a beverage can, is obviously different from the one needed to make railway tracks.
There are various types of steel, and the use of this alloy is widespread across industries and infrastructure owing to its many useful properties and characteristics.
Properties of Steel Tensile Strength Tensile strength is the amount of stress that a substance can take before becoming structurally deformed. The tensile strength of steel is comparatively high, making it highly resistant to fracture or breakage, which is a key point in its use in infrastructure building. Ductility One of the useful mechanical properties of steel, is its ability to change shape on the application of force to it, without resulting in a fracture.
This property is known as ductility, which enables it to be used in the making of different shapes and structures ranging from thin wires or large automotive parts and panels.
Malleability Malleability is closely linked with ductility, and allows steel to be deformed under compression. It allows this alloy to be compressed into sheets of variable thicknesses, often created by hammering or rolling. Durability The hardness of this alloy is high, reflecting its ability to resist strain. It is long-lasting and greatly resistant to external wear and tear.
Hence it is considered a very durable material. Conductivity Steel is a good conductor of heat and electricity. These properties make it good choice for making domestic cookware, as well as electrical wiring. Luster One of the physical properties of steel is its attractive outer appearance. It is silvery in color with a shiny, lustrous outer surface. Rust Resistance The addition of certain elements, makes some types of steel resistant to rust. Stainless steel for instance contains nickel, molybdenum and chromium which improve its ability to resist rust.
In addition to the above, the following is an indicative properties chart, which illustrates the differences in the properties of different types of steel. Steel is identified by grades, which are defined by specific organizations that set standards for grading.
Mild steel and two grades of stainless steel, and are discussed below.
EN8 CHEMICAL AND MECHANICAL PROPERTIES PDF
Moogushura Good heat treatment results on sections larger than 65mm may still be achievable, but it should be noted that a fall-off in mechanical properties would be apparent approaching the centre of the bar. Compared to normal Mild Steel, bright Abd Steel provides tighter sectional tolerances, increased straightness, and a much cleaner surface. It is therefore recommended that larger sizes of EN8 steel materials are supplied in the untreated condition, and that any heat treatment is carried out after initial stock removal. January 3rd, 0 Comments. EN8 is suitable for all round engineering purposes that may require a Steel of greater strength. Buy EN8 mild steel online at Metals4u.
