Steel Dominance Over Automobile Industries


Unquestionably the most common material used in building Automobiles are steel. Steel is easy to work with, strong, cheap and readily available. So most car bodies are built from steel. Also it doesn’t take extremely specialized tools or knowledge to produce, manufacture and repair steel. The steel is mainly used for car roof, chassis, wheels, brakes, exhaust and engine.

As per the research around 900 kg of steel is used per vehicle. Steel usage is as follows.

i) 34% of steel is used in body structure, panels, doors and trunk closures for high strength and energy absorption in case of a crash.

ii) 12% is used in the suspension, using rolled high strength steel strip.

iii) 23% is in the drive train consisting of cast iron for the engine block and machinable carbon steel for the wear resistant gears.

iv) The remainder is found in the wheels, tyres, fuel tank, steering and braking systems.

 
Manufactures use steel because, it is the strongest and most affordable material out there for the application and can be engineered in a lot of different ways to meet the needs of crash safety and vehicle performance. Newer steel such as advanced high strength steel are doing good performance with less steel at a lighter weight.

Steel is infinitely recyclable and that’s of huge importance. Even recycled back into same product it does not degrade in quality which is called closed loop. Also steel is magnetic that makes it easy to draw out steel from any form.

Experts and researchers are constantly trying to make a better steel to meet the new challenges  that automobile customers are facing in terms of security and style. Steel suppliers in UAE have a great role in investing more money on research of new steel type with better qualities and possibilities.

Game of Steel Balls Powering Industries

Image
In childhood boys have a fancy over ball bearings and steel balls as they play with those unused ball bearings to built up their miniature heavy truck   or toy.But actually steel balls have a large scale applications from small scale to large scale industries in various roles.Have a little discussion on the steel ball game powering our industries. How a Ball is Made In the first step, heading machines cut wire into short lengths and form it into spherical shapes between dies. Deflashing : The flash line, a ridge left by the forming dies, is removed as balls roll between heavy, cast iron plates. Soft Grinding: Similar to deflashing, except that a grinding stone is used to improve precision. Heat-treating: Carbon steel balls are next carburized and hardened. Heat treatment imparts the desired hardness and case depth. Descaling: This step removes the residues and by-products from the heat-treating process. Hard Grinding:

HY - 80 The Submarine Steel: Facts to Know

Image
HY-80 is a high-tensile, high yield strength, low alloy steel. It was developed for use in naval applications, specifically the development of pressure hulls for the US nuclear submarine program and is still currently used in many naval applications.The first production submarines to use HY-80 steel were the Permit class. These reportedly had a normal operating depth of 1,300 feet, roughly two-thirds the crush depth limit imposed by the steel. Manufacturing of HY -80 HY-80 steel is a member of the low carbon, low alloy family of steels with nickel, chromium and molybdenum (Ni-Cr-Mo) as alloying elements and is hardenable. The weldability of the steel is good, though it does come with a set of challenges due to the carbon and alloy content.[12] The carbon content can range from 0.12 to 0.20 wt% with an overall alloy content of up to 8 wt%. It is also used extensively in military/navy applications with large thick plate sections that add to the potential weldabili

Why Steel Is Used For Rails?

Earlier wooden rails were used on horse drawn wagon ways.The first steel rails used anywhere in the world were laid in Derby station on the Midland Railway in 1857. Steel is a much stronger material, which steadily replaced iron for use on railway rail and allowed much longer lengths of rails to be rolled. Composition of rail steel The basic requirement of rail steel is that it should be hard, wear resistant and crack resistant. This is achieved by steel composition and cooling of the hot rails. These properties of steel are achieved through control of carbon (C) and manganese (Mn) contents. Carbon content of rail steel can go up to a maximum of 0.82 % and manganese content up to a maximum of 1.7 %.   The normal rails are made of steel containing 0.7% C and 1% Mn, which are called as C-Mn rail steel. From a strength perspective (ultimate tensile strength of 880 MPa or 90 Kg/ Sq mm), the C-Mn rail is popularly known as 90 UTS rail or Grade 880 rail. This grade of rail
