Metals and their difference - Blog 8

There are a wide variety of metals present in the world apart from steel and they are used for many different purposes in all different kinds of industries, even in day to day activities. Further let us see how these metals are different from each other.

IRON:

It is one of the oldest metals which has been in use from the evolution of mankind. Even today it has its use in modern applications in construction and daily needs in the form of steel.


CAST IRON AND WROUGHT IRON:

These two types of iron are differed by the amount of carbon content in them. CAST IRON is the raw form of iron and it contains 2-4% of carbon. It is very hard and brittle. Whereas WROUGHT IRON has very low carbon content of 0.08% which makes it more ductile and gives high tensile strength. It is used in heavy machinery bases, frames and stoves as it can withstand high temperature.  

                                                   

METAL:

A metal is pure chemical element, like on the periodic table. Elements are divided into metals and non-metals. “Metal” occurs naturally in nature, has a lustre, are good conductors of heat and electricity, and are much denser than non-metals. There are 5 main categories of metals like Base metals, Ferrous metals, Noble metals, Precious metals & Heavy metals.

ALLOY:

Alloys are man-made materials made by combining a metallic element with something else. Alloys can involve combining a metal with metals, non-metals, or both. Steel, Brass Bronze, etc. are all alloys. Used in dental fillings (amalgam),posing as musical instruments or door knobs (brass), as jewellery (white gold), as artwork (bronze statues), in cars and planes (duralumin), on guns (gunmetal), inside electronics (solder), holding up buildings (steel) etc

STEEL:

It is a most common metal in the modern world that is widely used in all industries. Steel is iron mixed with carbon (99% iron and 1% carbon). The ratio varies for different applications and it’s classified into types like Carbon steel, alloy steel, tool steel, stain less steel etc.

                                                     

STAINLESS STEEL:

This is basically just steel with a noticeable amount of chromium in order to increase the corrosion resistance. The chromium creates a super thin barrier when it corrodes which slows rust. If you scratch off the barrier, a new one will immediately form. It is widely used in kitchens; knives, tables, utensils, tools, instruments etc. Just because it is stainless steel, that doesn’t mean that it can’t rust. It will rust if not cleaned and properly cared for.

                                                                 

BRONZE:

It is an alloy of tin and copper. The use age of bronze goes up to the Bronze Age where it was most commonly used in sculptures, coins etc. Bronze was the first man-made alloy. Even today is it’s used I coins, church bells, springs and bearings, guitar strings etc.

                                                                     

BRASS:

Brass is an alloy of copper and zinc. It is really useful for a number of reasons. Its goldish colour makes it really popular for decorations. It is used in antique furniture as handles and knobs, instruments like tubas, trumpets and trombones as they are very much ductile and malleable. It is also a durable metal which lasts for long time.

                                                                       

ALLUMINIUM:

Aluminium was first made in the 18th century and since then it has a wide variety of uses. It is non ferrous metal having very high strength-to-weight ratio. It’s malleable, and it doesn’t rust. It can be made  into a really thin sheet so it’s widely used in manufacture of aircrafts parts and soda cans.

Environmental impact of steel

Steel is important for construction,but it also affects the environment.The world produces a lot of steel over 240 kilos for every single person in the world every year .Steel production is one of the most energy consuming and CO2 emitting industrial activities in world. Environmental impact of steel production: Mining of iron ore : the main raw material for steel is iron ore is mined a year about 95 percent is used by the steel industry. The mining of iron ore is highly energy intensive and causes air pollution in the form of nitrous oxide,carbon dioxide,carbon monoxide,sulfur dioxide from diesel generators,trucks and other equipment. The mining of iron ore also cause water pollution of heavy metals and acid that drains from the mines.Acid drainage can go on from thousand of years after the mining activitie

Steel Erection, Fabrication and Hybrid construction -Blog 16

Image
This blog is about how the steel sections are transported to the site, the issues involved with transportation, erection and fabrication along with the onsite constrains. TRANSPORTATION: The steel sections have to transported from the manufacturing site to the fabrication site and this becomes a tough task due to their size. Often large pieces cannot be transported in a single part, they are split or divided and shipped as two separate pieces or even as one piece to avoid damage or scratches. Temporary connections are made on the pieces to avoid damage and to keep the parts in place during transportation.     These parts are not transported in normal vehicles but require long trail vehicles to fit their length and size which again becomes a difficult task to turn around the corners of the road and at junctions     FABRICATION & ON SITE CONSTRAINS: Fabrication of steel on sites which are along the main road or at the corner site is very hectic as there is very less staging area.
