1045 Steel – 1045 Steel Composition
One of the most commonly use materials in the world when it comes to blades and swords is definitely carbon steel. This simply means the steel is a plain carbon steel with 0.45% carbon content. Carbon content does not mean anything if the blade is not heat treated properly. This steel is heat treated. The use of 1045 Carbon Steel actually makes sense. One of the most frequently asked questions when it comes to buying cold finished steel products is which among these blades are good for the purpose for which it was intended to be bought. The glaring differences lies in the chemical makeup and mechanical properties of these steel. 1045 Carbon Steel contains the following chemical makeup:
Iron content is from 98.51 to 98.98%
Carbon content is 0.45%
Manganese content- from 0.60 to 0.90%
Phosphorus is 0.04%
Sulfur is 0.05%
Tensile strength- 91,000 psi
Yield strength- 77,000 psi
Elongation in 2 inches- 12%
Reduction in Area- 35%
Brinell Hardness- 179
Real Life Applications
Since 1045 Steel has higher content and higher tensile strength it is not easy to weld. Therefore 1045 Carbon Steel is selected for applications involving the need for strength in a blade. 1045 Katana are usually inexpensive to produce which is why it cost less when sold. Experts agree though that since 1045 steel falls under the ideal range for durable and sharp swords it is usually a good choice for buyers as compared to the other forms of steel. 1045 carbon steel contains from 0.5 to 0.7 carbon content. 1060 is harder than this steel though. 1045 steel is used in gears, axles, bolts, studs, shafts and machine parts.
Uses for Carbon Steel
Carbon steel is a combination of carbon and iron. Depending on the amount of carbon content in the alloy this steel falls under four grades which include: low, medium, high and ultra-high carbon steel. These classifications have different uses across various industries that need heavy duty metal material. Carbon steel is strong enough to use in manufacturing aircraft. It can be used to build fences and gates. It also has applications in the field of ship making and automobile parts. For the purpose of this article, it is used basically to create blades for knives and swords.
