This element can be pure, it is a hard magnetic silver metal. It is also found in the inner and outer core of the earths surface
What is Iron
100
Contains trace amounts of alloying elements. Count for 90% of total steel production
What is Carbon Steel.
100
In 1855, this process was the 1st inexpensive process for mass producing steel from molten pig iron.
What is the Bessemer Process.
100
This allows steel to be relatively light in weight, but is also very strong.
What is High Strength/ Weight ratio
100
This process for cutting steel uses a blade that rotates very slow, with the help of coolant to cool the blade.
What is Cold Sawing
200
This type of Iron contains as much carbon as it can hold. It is heated until it become a liquid, and then poured into a mold/cast to solidify.
What is Cast Iron
200
Combined w/ elements other than carbon. Elements allow strength, resistant to corrosion, very hard. Example: Aluminum, nickle, Copper.
What is Alloy Steel.
200
This was the main concept for using the Bessemer process.
What is using oxidation to remove impurities from the iron.
200
Name (3) disadvantages to Steel
General Cost, Fire Proofing, Maintenance, Susceptibility to buckling.
200
This process of cutting steel uses a flame to cut.
What is Oxygen-Acetylene cutting.
300
This type of Iron is usually smelted with coke (baked coal) & limestone in a blast furnace. It also has very high carbon content. Usually used to make steel.
What is Pig Iron
300
This type is usually used with concrete, helps to hold things together.
What is Reinforcing steel.
300
This process is the Refined version of the Bessemer. The oxygen is forced through the molten iron from the top rather than from the bottom.
What is The Basic Oxygen Process.
300
An advantage to steel that allows large plastic deformation.
What is Ductility.
300
This type of Welding is wire fed, and is praised for being faster, cheaper, and easier to use
What is MIG welding/ Metal Inert Gas
400
a hard, strong, gray or bluish-gray alloy of iron with carbon and usually other elements, used extensively as a structural and fabricating material. made up of Iron and carbon.
What is Steel.
400
This type of steel consists of Plates, bars, pipes, shapes used in construction of buildings, bridges, structures.
What is Structural Steel.
400
This process uses 4 regenerators to help produce heat to the pig iron to help make it molten.
What is The Open Hearth Process.
400
How long something can withstand a given number of cycles without failing. Also an advantage to steel.
What is Good Fatigue Strength.
400
This type of welding is usaully manual, and uses a rod with flux to help shield contaminates in the air.
What is Stick Welding/ Shielded Metal Arc
500
The most abundant metal/element available on earth. Also has the symbol Fe.
What is Iron
500
Made up of 10-20% chromium as the main alloying element. Also, it has high corrosion resistance.
What is Stainless Steel
500
** Daily Double** This is sometimes added to the molten pig iron to help mix with the impurities to create slag, which will later be seperated.
What is Lime.
500
Name the (4) Advantages of steel discussed in class.
1) High Strength/ Weight ratio. 2) Ductility 3) Predictable Material Properties 4) Fatigue Strength
500
This type of welding is more expensive, time consuming and is used on thinner material. Also wire fed.
