slideshare.netSteel is an alloy of iron and carbon, and sometimes other elements. Iron is the base metal of steel. In pure iron, the crystal structure has relatively little resistance to the iron atoms slipping past one another, and so pure iron is quitecharacteristics of steel The carbon in typical steel alloys may contribute up to 2.14% of its weight.

Properties of Steel. For example, stainless steel which is rust resistant, relatively weak, and finds use in cutlery and knives contains a minimum 10.5 percent chromium. Steels used in construction fall into three types: carbon-manganese steel; high-strength, low-alloy (HSLA) steel; and high-strength quenched and tempered alloy steel.
Properties of Steel. Steel is an alloy, consisting mainly of iron, with a carbon content of 0.2% to 2.1% by weight. 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,characteristics of steel
Steel is an alloy of iron and carbon, and sometimes other elements. Because of its high tensile strength and low cost, it is a major component used in buildings, infrastructure, tools, ships, automobiles, machines, appliances, and weapons. Iron is the base metal of steel. Iron is able to take on two crystalline forms, body centered cubic and face centered cubic, depending on its temperature. In the body-centered cubic arrangement, there is an iron atom in the center and eight atoms at the vertic
What Are the Different Types of Steel? Carbon Steels. Carbon steels contain trace amounts of alloying elements and account for 90%characteristics of steel Alloy Steels. Alloy steels contain alloying elements (e.g. Stainless Steels. Stainless steels generally contain between 10-20% chromium ascharacteristics of steel Tool Steels. Tool characteristics of steel
This means that structures made from steel can be erected in a much lesser time, and hence steel is preferred as a building material over others. 2. Reduced cost. As steel components used in buildings are manufactured off-site, there is a limited requirement for on site construction, which means reduced labour costs.
Tensile Properties of Structural Steel There are different categories of steel structures which can be used in the construction of steel buildings. Typical stress strain curves for various classes of structural steel, which are derived from steel tensile test, are shown in Figure 2.

There are three groups of stainless steels: Austenitic steels, which are very high in chromium, also contain small amounts of nickel and carbon. Ferritic steels contain about 15% chromium but only trace amounts of carboncharacteristics of steel Martensitic steels contain moderate amounts of chromium, nickel, and characteristics of steel
Owing to its material properties, steel is possibly the most important engineering and construction material in the world. The most important properties of steel are great formability and durability, good tensile and yield strength and good thermal conductivity.

Stainless steels are
Engineering Thermal Properties of Metals, Conductivity, Thermal Expansion, Specific Heat Data - Metals in general have high electrical conductivity, high thermal conductivity, and high density. Typically they are malleable and ductile, deforming under stress without cleaving.
AISI 4140 alloy steel can be welded using all conventional techniques. However, the mechanical properties of this steel will be affected if it is welded in the heat-treated condition, and post-weld heat treatment should be performed. Heat Treatment. AISI 4140 alloy steel is heated at 845C (1550F) followed by quenching in oil.
Steel, alloy of iron and carbon in which the carbon content ranges up to 2 percent (with a higher carbon content, the material is defined as cast iron). By far the most widely used material for building the worlds infrastructure and industries, it is used to fabricate everything from sewing needles to oil tankers.
Characteristic strength of steel which Steel Fabrication Company Singapore defined as that value of resistance below which not more than a prescribed percentage of test results may be expected to fall.
Mild steel, also called plain-carbon steel, is a type of steel alloy which is the most common high volume steel in production. Mild steel contains a small amount of carbon and provides material properties that are acceptable for many applications.
The physical properties of steel include high strength, low weight, durability, ductility and resistance to corrosion. Steel, as we all know, offers great strength though it is light in weight. In fact, the ratio of strength to weight for steel is the lowest than any other building material available to us.
Mechanical Properties. The mechanical properties of steel often depend on their grade, or chemical makeup. For that reason, it is never safe to make assumptions about the mechanical properties of hot rolled vs cold rolled unless they are the same grade. Using the very common 1018 as an example, the chemical properties of 1018 steel will be the characteristics of steel
Lecture Ten: Characteristics of Steel as Used in Building: Composition: Steel consists of layers of iron ore, coke (a form of carbon), and limestone. Strength and malleability of the steel are functions of the carbon content. Carbon contents are as follows: 1) Cast iron= 3-4% carbon 2) High carbon steel= less than 2% carbon
Mild steel (iron containing a small percentage of carbon, strong and tough but not readily tempered), also known as plain-carbon steel and low-carbon steel, is now the most common form of steel because its price is relatively low while it provides material properties that are acceptable for many applications.
Tables of Technical Properties* of Stainless Steels (flat products) The selection of the appropriate stainless steel grade for each applic ation is the result of variou s considerations. In order to assis t the reader in this selection, Euro Inox makes the following tables of technical properties available:
The amount of carbon within mild steel changes its properties to become stronger and harder. Industry-grade mild steel requires 210,000 Mpa elasticity. Because it is a soft material, mild steel is easy to weld, whereas high-carbon steels, such as stainless steel, require the use of specialized welding techniques.
In order for steel to be considered low carbon steel, there are certain characteristics it must meet. For instance, the steel has to have less than .3 percent carbon in its total makeup to be considered low carbon. Low carbon steel also contains pearlite and ferrite as major components.
Steel in most cases performs far better in earthquake than most other materials because of these properties. However one important property of steel is that it quickly loses its strength in a fire. At 500 degrees celsius (930 degrees F), mild steel can lose almost half its strength.
AISI 1020 has low hardenability properties and is a low tensile carbon steel with a Brinell hardness of 119 235, and a tensile strength of 410-790 MPa.
