S15C is a type of steel and is a general-purpose steel called "carbon steel for mechanical structures."
The carbon content is 0.13-0.18%, which is low carbon steel (low carbon steel).
S15C is high-quality carbon steel

USE
S15C lost wax investment casting is used to produce carburized parts, fasteners, stamping molds, and low-load parts that do not require heat treatment, such as bolts, screws, braces, flanges, chemical containers, steam boilers, etc.
S15C Mechanical Characteristics
It is used to manufacture parts and carburized parts with low stress and high toughness requirements, fasteners, and die forgings, as well as low-load parts without heat treatment.
Advantages of S15C
Unlike SS400, the contents of the five major elements are fixed and the ingredients are specified, thus reducing quality changes caused by differences in material libraries and batches.
S15C can ensure a certain degree of strength and toughness. Since low carbon content high toughness, it can achieve both strength and toughness to a certain extent.
Applications of S15C
Used in automotive parts, gaskets, various structural parts, etc.
Correct use of S15C and S45C
The difference between S15C and S45C is the amount of carbon. S45C can be quenched as a whole, but S15C cannot be quenched without carburizing and quenching. 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, "S15C+ carburizing and quenching" can be used.
Approach:
• Processability
It has relatively good machinability and can be said to be an easy material to cut.
• Welding
S15C has low carbon content and is not prone to welding cracks. However, if you want to improve the welding quality, SCM is more suitable.
About surface treatment and quenching
• Due to electroplating
S15C does not have anti-rust properties and is often used after electroplating to prevent corrosion and improve wear resistance.
"Black dyeing" is cheap and highly accurate but has a low anti-rust effect, "electrolytic nickel plating" is highly accurate and easy to control the film thickness, and "hard chromium plating" can achieve high hardness without quenching. You can due to the quenching
S15C has low carbon content and cannot be hardened by general overall quenching. Therefore, "carburizing and quenching" in which carbon is added to the surface layer while quenching is performed is appropriate. Can increase surface hardness while maintaining internal toughness.
