The cementation process is an obsolete technique for making steel by carburization of iron. Unlike modern steelmaking, it increased the amount of carbon in the iron. It was apparently developed before the 17th century. Derwentcote Steel Furnace, built in 1720, is the earliest surviving example of a cementation furnace. Another example in the UK is the cementation furnace in Doncaster Street, Sheffield.
The process was described in a treatise published in Prague in 1574. It was again invented by Johann Nussbaum of Magdeburg, who began operations at Nuremberg (with partners) in 1601. The process was patented in England by William Ellyot and Mathias Meysey in 1614. At that date, the "invention" could consist merely of the introduction of a new industry or product, or even a mere monopoly. They evidently soon transferred the patent to Sir Basil Brooke, but he was forced to surrender it in 1619. A clause in the patent prohibiting the import of steel was found to be undesirable because he could not supply as much good steel as was needed. Brooke's furnaces were probably in his manor of Madeley at Coalbrookdale (which certainly existed before the English Civil War) where two cementation furnaces have been excavated. He probably used bar iron from the Forest of Dean, where he was a partner in farming the King's ironworks in two periods.
I Am may refer to:
Wrought iron is an iron alloy with a very low carbon (less than 0.08%) content in contrast to cast iron (2.1% to 4%). It has fibrous inclusions known as slag up to 2% by weight. It is a semi-fused mass of iron with slag inclusions which gives it a "grain" resembling wood, that is visible when it is etched or bent to the point of failure. Wrought iron is tough, malleable, ductile, corrosion-resistant and easily welded. Before the development of effective methods of steelmaking and the availability of large quantities of steel, wrought iron was the most common form of malleable iron.
A modest amount of wrought iron was used as a raw material for refining into steel, which was used mainly to produce swords, cutlery, chisels, axes and other edged tools as well as springs and files. The demand for wrought iron reached its peak in the 1860s with the adaptation of ironclad warships and railways. However, as properties such as brittleness of mild steel improved, it became less costly and more widely available than wrought iron, whose usage then declined.

Hello All, I am Ric Furrer of www.doorcountyforgeworks.com A forging video showing the making of an old steel called Blister Steel. Basically it is wrought iron which has had carbon added. This addition of carbon allows the steel to hardened with a quench and can be used for tools...such as knives. Special guest Robert Rossdeutscher of rnrknives.com whom I am walking through the process with me filming. This is a teaser for a longer video which will be for sale soon.
A one off experiment to see if I can turn some low carbon scrap into high carbon high end cutlery. In this first episode I make 2 small batches of blister steel by baking a batch of wrought and some mild steel at high temperatures with a charcoal compound. Using time and temperature the amount of carbon the iron absorbs can be approximately controlled. Sorry for the low sound during explanations, I will turn it up on the next one, though it may mean some louder machine noise!! Difficult to find a balance.

Hello All, I am Ric Furrer of www.doorcountyforgeworks.com A forging video showing the making of an old steel called Shear Steel. Basically it is wrought iron which has had carbon added to it..this is then Blister Steel. The Blister steel is then forge-welded one or more times made to hardened with a quench and can be used for tools...such as knives. Special guest Robert Rossdeutscher of rnrknives.com whom I am walking through the process with me filming. This is a teaser for a longer instructional video which will be for sale soon.
This video shows techniques for refining wrought iron as well as carburizing the iron and how to turn it into shear steel. To round it off, I make a san-mai construction knife to show off the results that can be achieved by these techniques. Forge diaries are rough and unpolished videos that show some of the work I do at the forge. These short episodes capture various random activities including failed experiments and small tips and tricks. They allow me to publish status updates while I am working on larger projects.

Blip, blap, mind blown. Yes, it will have to be forged to homogenize the carbon throughout the steel but it's a thin piece and there's ample carbon. Hey, in the end, we just used Tums to turn iron into steel! If anyone can share why the first iron bars in the video cracked so aggressively or have heard of cold short iron let us know by posting in the comment section. Know where to get quality wrought iron? Let everyone know in the comment section, it's a bit hard to find. YouTube's made changes.

Part Deux as I continue with my mission to make a fine knife steel out of some old ganky iron and mild bar from the scrap bin. In this installment I take the newly made Blister steel, and refine it by folding it....making shear steel, in each fold the carbon is equalized. I then mix together the two batches of blister steel and continue to refine it........So lots of folding, here's hoping this one does not go ping when I clay and water quench the 12 inch blade in the next installment.

We recycle history by turning antique wagon wheels into a heirloom blade. This video shows the whole process from preparing the wrought iron to the finished knife. First, the wagon tire is forged and prepared for melting in the crucible. A crucible steel bar is forged from the ingot and then turned into a powerful blade. Finally, everything is put together and you can marvel at the carbide grain structure of the blade.

The Past and Future of the American Steel Industry Documentary | History TV. Welcome to HISTORY TV - home of the best documentary films and documentary movies on history and many more! Steels are alloys of iron and other elements, primarily carbon, widely used in construction and other applications because of their high tensile strengths and low costs. Carbon, other elements, and inclusions within iron act as hardening agents that prevent the movement of dislocations that otherwise occur in the crystal lattices of iron atoms. The carbon in typical steel alloys may contribute up to 2.1% of its weight. Varying the amount of alloying elements, their formation in the steel either as solute elements, or as precipitated phases, retards the movement of those dislocations that make iron compara...
How Wealthy Is America (US) In Its Steel Industry Documentary Movies | History Channel. Welcome to HISTORY CHANNEL - home of the best documentary films and documentary movies! Steel is an alloy of iron and other elements, primarily carbon, that is widely used in construction and other applications because of its high tensile strength and low cost. Steel's base metal is iron, which is able to take on two crystalline forms (allotropic forms), body centered cubic (BCC) and face centered cubic (FCC), depending on its temperature. It is the interaction of those allotropes with the alloying elements, primarily carbon, that gives steel and cast iron their range of unique properties. In the body-centred cubic arrangement, there is an iron atom in the centre of each cube, and in the face-centred ...

Solid Steel (2nd August): "It's another special show as our own DJ Moneyshot presents another classic album deconstructed for the Solid Steel 25th Anniversary. Public Enemy's 'It Takes A Nation of Millions to Hold Us Back' is also 25 years old and to honour both occasions DJ Moneyshot shows us once again why he's the mixtape king with the career-best offering, Solid Steel and the Hour of Chaos. Over 60 blistering minutes he takes in all the beats, breaks, samples and spoken word nuggets that made this seminal Bomb Squad production such an explosive release. Amongst the vast stack of tracks in the mix, expect words of wisdom from Louis Farrakhan, exclusive interviews with Hank Shocklee, and all the soul, rock 'n' roll and early rap tracks that went into making up P.E's (if not hip-hop's) fi...
