It is often used when large quantities of class='bold'>class='bold'>steel are needed, for example as structural class='bold'>class='bold'>steel.

class='bold'>class='bold'>Carbon from the oil can diffuse into the class='bold'>class='bold'>steel, making the surface very class='bold'>hard.

class='bold'>class='bold'>Steel is a mixture of Iron and between 0.3 to 1.7 class='bold'>class='bold'>Carbon by weight.

Since the 1960s, the class='bold'>class='bold'>steel industry has made considerable efforts to limit environmental pollution, reducing by half both energy consumption and class='bold'>class='bold'>carbon class='bold'>dioxide emissions per ton of class='bold'>class='bold'>steel produced.

Upon exposure to air, it forms a class='bold'>solid class='bold'>class='bold'>carbonate salt with class='bold'>class='bold'>carbon class='bold'>dioxide.

class='bold'>class='bold'>Steel with a higher class='bold'>class='bold'>carbon percentage may be brought to a higher state of maximum class='bold'>hardness.

A research team in Germany published a report in 2006 revealing nanowires and class='bold'>class='bold'>carbon nanotubes in a blade forged from Damascus class='bold'>class='bold'>steel.

One of the class='bold'>materials that can do this is a remarkable class='bold'>material, class='bold'>class='bold'>carbon, that has changed its form in this incredibly beautiful reaction where graphite is blasted by a vapor, and when the vaporized class='bold'>class='bold'>carbon condenses, it condenses back into a different form chickenwire rolled up.

If the class='bold'>class='bold'>carbon content is between 0.25 and 2 , the resulting metal is tool grade class='bold'>class='bold'>steel, which can be heat treated as discussed above.

When the class='bold'>class='bold'>carbon content is below 0.25 , the metal is either wrought iron (wrought iron is not smelted and cannot come from this process) or mild class='bold'>class='bold'>steel.

class='bold'>class='bold'>Steel is an alloy of iron and class='bold'>class='bold'>carbon containing less than 2 per cent of class='bold'>class='bold'>carbon and 1 per cent of manganese (and small amounts of silicon, phosphorous, sulphur and oxygen).

It can be coloured white by the addition of titanium class='bold'>dioxide for optical absorbance or luminescence detection or black by the addition of class='bold'>class='bold'>carbon for fluorescent biological assays.

Building class='bold'>material is any class='bold'>material which is used for construction purposes.

Peace is not a far fetched idea.

Wootz class='bold'>class='bold'>steel which is also known as Damascus class='bold'>class='bold'>steel was a unique and highly prized class='bold'>class='bold'>steel developed on the Indian subcontinent as early as the 5th century BC.

Thus, with glucose it gives class='bold'>class='bold'>carbon class='bold'>dioxide 3 KClO4 C6H12O6 6 H2O 6 CO2 3 KClThe conversion of class='bold'>solid glucose into hot gaseous CO2 is the basis of the explosive force of this and other such mixtures.

However, there is no simple centre that collates the information produced and some statistics particularly those on deforestation, the population that uses class='bold'>solid fuels, and class='bold'>class='bold'>carbon class='bold'>dioxide emissions, are generated at irregular intervals.

The term does not refer to a known class='bold'>solid compound it exists only in aqueous solution containing the calcium (Ca2 ), biclass='bold'>class='bold'>carbonate (HCO3 ), and class='bold'>class='bold'>carbonate (CO32 ) ions, together with dissolved class='bold'>class='bold'>carbon class='bold'>dioxide (CO2).

The class='bold'>solid product formed is HgSe.

The UK gas and electricity markets authority, Ofgem, released a statement in 2011 accepting the use of class='bold'>class='bold'>Carbon 14 as a way to determine the biomass energy content of waste feedstock under their administration of the Renewables Obligation.

I hate chemistry.

class='bold'>class='bold'>Carbon class='bold'>class='bold'>steel contains 2.0 class='bold'>class='bold'>carbon or less, with small amounts of manganese, sulfur, phosphorus, and silicon.

Alloyed class='bold'>class='bold'>steels account for a relatively small portion of all finished class='bold'>class='bold'>steel products, and their production and use are concentrated in developed countries and China.

A great' year is a year of premium prices (higher than the US price) for class='bold'>class='bold'>steel in the world class='bold'>class='bold'>steel export market.

An increase in the stock price of class='bold'>class='bold'>steel manufacturers suggests an increase in the demand for class='bold'>class='bold'>steel, which induces entrepreneurs to start more class='bold'>class='bold'>steel plants and investors to provide them with the money.

Perhaps the most important polymorphic form of class='bold'>class='bold'>steel is martensite, a metastable phase that is significantly stronger than other class='bold'>class='bold'>steel phases.

Certain grades of class='bold'>class='bold'>steel are sensitive to the 78 nitrogen which was part of the air blast passing through the class='bold'>class='bold'>steel.

Mathematics is an interesting subject.

I do not like science.

So, it's tens of millions of calculations just to design one connection between a piece of structural class='bold'>class='bold'>steel and another piece of structural class='bold'>class='bold'>steel.

Of course, the effects spread through the economy as demand for cars falls, demand for class='bold'>class='bold'>steel also falls, and class='bold'>class='bold'>steel workers are laid off.

Tenaris Siderca (class='bold'>class='bold'>steel) is one of the successful Argentine companies investing abroad and is developing a global production network for seamless class='bold'>class='bold'>steel pipes.

Others involve small changes in industrial processes, such as the use of inputs that emit less class='bold'>class='bold'>carbon in class='bold'>class='bold'>steel and cement production, as well as large ones, such as a changeover within Europe to lower class='bold'>class='bold'>carbon manufacturing facilities.

It makes up about 8 by weight of the Earth's class='bold'>solid surface.

The global class='bold'>class='bold'>steel market has historically been marked by cyclical fluctuations.

Note Production refers to crude class='bold'>class='bold'>steel, consumption to finished class='bold'>class='bold'>steel products.

Thin flat products find end use applications in automotive body panels, domestic white goods products, tin cans and a range of other everyday products containing class='bold'>class='bold'>steel.
