"The Knowledge behind the blades"
In blacksmithing the standards for classifying the characteristics of the steel was done during the early 1940's buy the Society of Automotive Engineers also known as the (S.A.E) and the American Iron and Steel Institute also known as the (A.I.S.I) in which they designated a coding system to define the types and grades of steel available. In this the classifications contains 4 to 5 numeric characters with additional letters to designate special characteristics of the steel such as 1080, 5160, L6, and 52100. The very first number depicts the general category of steel. Which is:
|
<Number System >
1 2 3 4 5 6 7 8 9 |
< Type of Steel>
Carbon Steel Nickle Steel Nickle/Chrome Steel Molybdenum Steel Chromium Steel Chrome Vanadium Steel Tungsten Steel Nickle Chromium Vanadium Steel Silicon Manganese Steel |
The second number indicates if there are elements which are present that effect attributes of the steel. The last two digits (three digits for a few grades) indicate the actual amount of carbon percentage which is present.
For example:
1080 Steel :The zero next to the one such as 1o__ indicates that there is no major secondary element present. Therefore the main element is Carbon Steel. Where as the last two digits __80 indicate the actual amount of carbon percentage which is present which in this case is 80% Carbon Steel.
1095 Steel :The zero next to the one such as 1o__ indicates that there is no major secondary element present. Therefore the main element is Carbon Steel. Where as the last two digits __95 indicate the actual amount of carbon percentage which is present which in this case is 95% Carbon Steel.
