Steel is one of the most widely manufactured and most commonly used materials in human history. However, most of us do not know much about steel. How it is made, the composition of steel, and its properties. We’ve answered the internet’s most commonly asked questions about steel.
Steel is an alloy made from iron and carbon. There are several distinct grades of steel that have unique chemical compositions based on the different amounts of carbon and added alloys.
Magnets have been around for thousands of years, helping ships navigate oceans. Today, magnets are used for a wide variety of purposes, including microwaves, televisions, generators, motors, speaker systems and much more. There is some misunderstanding about what types of materials are magnetic – particularly steel. Is steel magnetic, can it be magnetized, or neither?
Both 1070 and 1095 are excellent grades of steel. However both have similar chemical and mechanical properties and purchasers often don't understand the small but significant differences of 1070 and 1095 steel. Below are chemical and mechanical property differences of 1070 and 1095 as well as common applications for both steel grades.
1070 and 1095 steel have different chemical properties, notably for their carbon and manganese composition. The chemical properties of 1070 and 1095 steel are the following.
Our 1045 and 4140 grade steels are both very popular options here at Capital Steel & Wire, and we often get questions related to their differences. 1045 and 4140 have distinct chemical and mechanical characteristics which make them valuable for different applications.
It is easiest to see the differences chemical differences between 1045 and 4140 by doing a side by side comparison with a chart.
Below is a chart for reference on hot rolled bar tolerances.
| Specified Sizes (Rounds or Squares) | Over | Under | Out-of-Round or Square | Machining Allowance - Minimum Stock Removal* |
| To 5/16" included | 0.005" | 0.005" | 0.008" |
0.016" |
4130 and 4340 are both popular steel grades at Capital Steel & Wire. Below is a chemical and mechanical properties comparison of both grades of steel as it may be of value for machining purposes and as a resource for purchasing 4130 and 4340 steel.
This low alloy steel contains high amounts of chromium and is often referred to as chromoly. 4130 steel has good machinability, ductility, weldability and strength characteristics. It is used for many different industries including the automotive, aerospace and machining industries.
Both 1040 and 1045 steels are popular at Capital Steel & Wire, and both have different chemical and mechanical characteristics. These also help determine different applications for both grades of steel.
To see differences in chemical characteristics of 1040 and 1045 it is best to do a side by side comparrison.
Bellow is a comparison chart with information about the chemical composition and the mechanical properties of both 1008 grade steel and 1018 grade steel. This information can be helpful for anyone involved in machining or is interesting in purchasing either 1008 or 1018 steel.
The chemical features of 1008 and 1018 steel are the following.
We get inquiries about the chemical composition and mechanical property differences between the 1060 grade and 1095 grade carbon steels. Below you will see several comparison charts that outline the chemical properties and mechanical properties of 1060 steel and 1095 steel. All of this may be useful for anyone involved in machining or who is interested in purchasing either type of steel.
