In this article, let Baowu show you the difference between low carbon steel, medium carbon steel and high carbon steel?

First of all, the difference between the three is mainly the difference in carbon content. Low carbon steel refers to unalloyed steel with carbon content below 0.25%, medium carbon steel refers to unalloyed steel with carbon content maintained at 0.25% to 0.6%, and high carbon steel refers to non-alloy steel with carbon content exceeding 0.6%. Alloy steel, the carbon content of steel commonly used in the market is maintained at 0.6% to 1.2%.

Low carbon steel has poor hardness and low strength due to its low carbon content, but has strong plasticity and good elasticity, so it is generally used in oil pipelines, structural bearing, or special-shaped pipe transportation. In addition to this, mild steel has good weldability and is easy to accept various processing such as forging, welding and cutting. Often used to make chains, rivets, bolts, shafts, etc.

The carbon content of medium carbon steel is higher than that of low carbon steel, the performance is relatively moderate, the plasticity and strength are also relatively moderate, but the weldability is poor, so it is widely used, mostly used in mechanical transmission, gears, etc. Manufacturing can also be involved.

High carbon steel has the strongest hardness and strength, but poor elasticity, so it is often used in machining, such as bearings, rings, etc. In addition, it can also be used for cutting tools and tool steel.

The above are the main differences and uses of low carbon steel, medium carbon steel and high carbon steel. You can choose carbon steel with different carbon content according to different uses.
