restricted to iron or products made from it .Iron is easily prone to rusting making its surface rough. Chemically‚ rust is a hydrated ferric oxide Titanic‘s bow exhibiting microbial corrosion damage in the form of ‘rusticles’ Rusting an Electrochemical Mechanism ; Rusting may be explained by an electrochemical mechanism. In the presence of moist air containing dissolved oxygen or carbon dioxide‚ the commercial iron behave as if composed of small electrical cells. At anode of cell‚ iron passes into

History of Iron and Steel I have researched the origin of hot metal cars for many years. In the very early years of iron production and later steel production historical is sketchy at best. Almost in plant equipment was built on sight and sometimes no drawings were used. The ability of American fabricators in the late 1700 and the 1800 amazes me. A case in point is Otto Mears a German immigrant that built most of the three foot gauge railroads in the Colorado Rockies. He had a third grade education

IRON (METAL) Iron is a chemical element with the symbol Fe (from Latin: ferrum) and atomic number 26. It is a metal in the first transition series. It is the most common element (by mass) forming the planet Earth as a whole‚ forming much of Earth’s outer and inner core. It is the fourth most common element in the Earth’s crust. Iron’s very common presence in rocky planets like Earth is due to its abundant production as a result of fusion in high-mass stars‚ Like other group 8 elements‚ iron

------------------------------------------------- Alloy Steel is a metal alloy whose major component is iron‚ with carbon content between 0.02% and 2.14% by mass. An alloy is a metallic solid solution composed of two or more elements. Complete solid solution alloys give single solid phase microstructure‚ while partial solutions give two or more phases that may or may not be homogeneous in distribution‚ depending on thermal (heat treatment) history. Alloys usually have different properties from those
