“Weathering steels or weather resistant (WR) steels are colloquial terms used to describe structural steels with improved atmospheric corrosion resistance.” (Corus, 2005). Weathering steel is indeed a group of steel alloys that when exposed to open air, oxidize to develop a…
Its mechanical properties are influenced by the percentage of different alloys constituent of the weathering steel. The most distinguishing characteristic feature of weathering steel is its anti-corrosive behavior exhibited through a self rusting procedure that is a byproduct of the unique nature of oxidization it undergoes, which is quite different to that experienced by unalloyed forms of steel. Although weathering steel experiences corrosion just like other steels in the beginning, the process is different once the rust layer is formed. Conventional steels undergo rusting to develop an unstable layer of rust, that would detach from the base metal with due course of time allowing for the process of rusting to continue. Thus the steel continues to corrode. It is the enhanced stability of the rust layer of weathering steel that distinguishes its rusting process from that observed in other steels. This paper evaluates the advantages and disadvantages of weathering steel, with special reference to its use as a construction material.
When the benefits of different metals are measured for use in structures and members exposed to weather, weathering steel shows a considerable edge over others on the basis of the following characteristic features.
Weathering steel attains the color of rust after some time of exposure to open air and under alternate cycles of drying and wetting. The beautiful rusty appearance of weathering steel is one of the reasons of its selection as a construction material because it is not possible to artificially produce the color and texture it owns naturally.
With its unique dark rusty purplish brown color, it appears very simple yet appealing to be used in various forms of art in general and the sculptures in particular. Street statues and monuments are commonly made of weathering steel. It is the same weathering steel, that lends the statues a rich texture and rusty shine. The intrinsically ...

Recently it was observed that the US steel industry has been effected by globalization. The US steel producers always want to be more competitive in a global market in order to strengthen themselves and take proper advantage of the opportunities that are prevalent in a global perspective.
Steel and iron are substances which revolutionized human life. It is difficult to think of a world without steel and iron. Most of the constructions and heavy equipment manufacturing are making use of steel and iron as the major raw material. No other material in the world is as useful as steel and iron as far as construction industry and heavy equipments manufacturing industry are concerned.
Weathering, or “the process of breaking down a rock” (Codrington 252), is an important geological process that initiates soil formation aside from mineralization and humification and organo-mineral complex formation. Often confused with erosion by lay persons, weathering can be classified into physical, chemical and biological.
The first part of the report provide an overview of each of the two companies under review, section two of each section analyses each of the companies by focusing on the profitability, liquidity and solvency ratios.
Globalization, the new information technology, and deregulation of financial markets and the quest for market dominance have eased the provision and search of finance.
Other major shareholders are NBFL1, UBL2, and HBL3 It is also listed on the Karachi Stock Exchange. The factory is situated in industrial area and spread over two plots of land measuring 75 acres (Company Profile).

It is assumed that the weakest element in the design is the flat plate of the buckle. Before testing, a numerical analysis to determine stress locations and magnitudes should be made in order to confirm appropriateness of design. If stresses in the material exceed Young's modulus, then a redesign should occur prior to test begin.
It is still the largest domestic steel producer in the U.S. although it does not produce as much steel as it would be expected. This paper looks at some of the aspects that apply to the American steel industry. This includes industry concentration, barriers of entry that
To start with Carnegie focused on making improvements in his steel manufacturing operations. His panache for innovation started with the introduction of Bessemer convertors in his steel manufacturing operations and by
However, there has been divided opinion on the socio-economic gains of this economic integration entity. This can be addressed more easily by drawing the comparative analysis of the advantages and disadvantages.
