S20c and S45c are two common cold drawn steel round bar materials, what are the differences between them? Here's a look:

1. Different chemical composition

In the chemical composition of S20c steel round rod, the content of carbon and manganese are low, 0.18%-0.23% and 0.30%-0.60%, respectively. In the chemical composition of S45c steel round rod, the content of carbon and manganese are higher, 0.42%-0.48% and 0.50%-0.80%, respectively. Therefore, the strength, hardness and other mechanical properties of S45c are better than S20c.

2. Different uses of steel

S20c steel round rods are usually used in the manufacture of low-strength parts, such as small gears, bearings, etc., while S45c steel round rods are used in some high-demand parts, such as axles, large gears, processing machines, etc.

3. Different heat treatment methods

The heat treatment methods of the two kinds of steel are different, the heat treatment method of S20c is generally normalizing + tempering, and S45c needs to undergo various processes such as quenching and tempering to obtain good mechanical properties.

4. Different cost

Due to the differences in chemical composition, mechanical properties, uses, etc., the cost of S45c steel round rods is relatively high, and S20c is relatively cheap.
