hardness vickers number for iron ore
Materials Properties
The methods used for testing hardness are the Brinell test which uses a hardened steel ball and produces a hardness number HB which can be used to compare the hardness of materials. The Vickers hardness test uses a diamond square based pyramid a microscope is needed to observe the indent the VHN is also used for comparisons....
Hematite: The mineral hematite information and pictures

Pig iron is created after iron ore is mixed with carbon in a series of furnaces. This material can be changed further into cast iron, steel or wrought iron depending on the selected manufacturing process. Cast iron is an iron carbon mixture that is generally used to pour sand castings, as opposed to making billets or bar stock....

Different Types of Iron Ore
Phosphorus in steel makes it brittle. For steelmaking the limit for phosphorus is one hundredth of one per cent for ten per cent of iron in the ore; this is the socalled Bessemer limit. A Bessemer ore carrying 52% of iron must not have more than .052% of phosphorus and the sulphur should not exceed .04%....

Hard Rock Mined Ore Truck Body
A truck body designed for transporting hard rock mined ore. The truck body includes a body floor having a first material forming a floor structure and a liner structure including a second material covering at least a portion of the floor structure. The second material has a hardness that is greater than a hardness of the first material and prevents wear of the truck body floor by the hard rock ......

The hardness of pure iron is around 100 on the Vickers Pyramid Hardness (VPH) scale, the units of which are 2. Absorbing enough carbon to form a %C steel (called a eutectoid steel) might raise its hardness to about 250 VPH. But quenching this steel (plunging the redhot artefact into cold water) might raise its hardness to 600 or ......
