Physical Properties of 5160 Steel

It is important to understand the naming system for steel and its alloys, as it explains a lot about the composition of each alloy. Like aluminum, steel is named using a four-digit identifier, but unlike aluminum, each number contains important information about the percentage of carbon and related alloying elements in the steel alloy. Also note that there are discontinuities between the AISI and SAE naming systems, but they often overlap in terms of alloy names, and will be discussed in this article (AISI/SAE naming index) as a naming convention.

The first digit of the steel alloy nomenclature represents the steel alloy class. In the case of 5160 aluminum, 5 represents steel alloys that use chromium as the main alloying element. The second digit represents the concentration of the alloying element mentioned above; 5160 steel is 1% chromium by mass. The last two digits represent the specific carbon concentration, which they determined to be 0.XX% carbon of the alloy. For 5160 steel, this means the carbon concentration is 0.60% carbon, making it a medium to high carbon steel. Note that this is not a comprehensive analysis and to be considered 5160 steel, the material must also reach concentration tolerances for other elements as shown below:

0.75-1% Manganese
0.035% Phosphorus
≤0.15-0.3% Silicon
≤ 0.04% Sulfur

5160 steel is extremely tough and flexible. It has high resistance to fatigue, high ductility and good spring properties useful for applications where flexibility is desired. Therefore, it is part of the "spring steels", which represent alloys that are both flexible and have sufficient strength to return to their original shape after deformation. While not easily welded or machined, 5160 steel can be heat treated, annealed and hot formed. Its density is 7.85 g/cm3 (0.284 lb/in3).

corrosion weakness
5160 steel rusts easily which is an unfortunate side effect that most steels will show. Oxygen in the air and water attacks the iron molecules in the steel and forms iron oxide, also known as rust, which can create cracks and weak spots in steel. Chromium is added to prevent this rusting, but not enough to completely prevent deterioration by mass. Any caustic damage will weaken 5160 steel, so it's important to consider hotsell your project's risk of rust when applying this metal.
