precision forging S15C carbon steel forgings

precision forging S15C carbon steel forgings

S15C is a type of steel, and is a general steel called "carbon steel for mechanical structure".

Carbon content is 0.13-0.18%, belonging to low carbon steel (low carbon steel).

S15C is a high-quality carbon steel

Mechanical properties of S15C

For manufacturing parts and carburizing parts with low stress and high toughness requirements, fasteners and die forgings, and low-load parts that do not require heat treatment.

Advantages of S15C

Unlike SS400, the content of the five major elements is fixed

, and the composition is specified, so the quality variation caused by differences in material libraries and batches can be reduced. →What are the five major metal elements?

S15C, which can ensure a certain strength and toughness,

can take into account both strength and toughness to a certain extent due to low carbon content = high toughness.

Advantages and Disadvantages of S15C

Less than SS400 = Poor Distribution

To put it poorly, S15C is a slightly semi-finished material. The quality of SS400 is slightly better than SS400 because the content of phosphorus and sulfur is specified.

Application of S15C

Used for automotive parts, washers, various structural parts, etc.

Proper use of S15C and S45C

The difference between S15C and S45C is the amount of carbon. S45C can be quenched as a whole, and S15C cannot be quenched without carburizing. In addition, S45C and S50C are more widely used as materials, and S45C is more widely used in mechanical parts.

When you want to increase the surface hardness while maintaining internal toughness, you can use "S15C + carburizing quenching".

Treatment method

Processing ◎

It has good machinability and can be said to be an easy-to-cut material.

Welding

S15C has a low carbon content and is not prone to welding cracks. However, if you want to improve the welding quality, SCM is more suitable.
