Carbon Steel (Grade SAE-1018)

Grade Introduction:

Here are many different categories of steel, and carbon steels are one such category that contains 0.12 to 2% carbon in them. The steel gains hardness and strength with heat treatment when the carbon percentage content increases; however its ductility is reduced.

SAE 1018 carbon steel is a free machining grade that is the most commonly available grade around the world. Although its mechanical properties are not very unique, it still can be easily formed, machined, welded and fabricated.

Supplied Condition:

Hot Rolled

Grade Applications:

SAE 1018 carbon steel is commonly used in high volume screw machine parts applications. The other applications of this alloy are as follows:

• Shafts
• Spindles
• Pins
• Rods
• Sprocket assemblies.
