Description
C15 is a plain carbon steel with a nominal 0.15% carbon content. It is a relatively low strength steel but it may be quenched and tempered for increased strength.
Applications
The low carbon steels, such as C15, are used for applications such as cold headed fasteners and bolts.

Processing & Fabrication
Soft Annealing
Heat to 850-950°C, cool slowly. This will produce a hardness of 90-100 HB.
Stress Relieving
Heat to approx. 540°C, hold for 1-2 hours, followed by air cooling. Performed to reduce distortion during heat treatment.
Forging
Hot forming temperature: 1200-950°C.
Machinability
Fairly good, especially cold drawn/worked. C15 has a rating of 55% compared to AISI 1112 (100%).
Corrosion Resistance
Plain carbon steel, no corrosion resistance. Will rust unless protected.
Welding
May be welded by all standard welding techniques.
Cold Working
Easily cold worked by traditional means. Following severe cold working, a stress relief or full anneal is recommended.
Note: This steel is generally used in the annealed or case-hardened condition. It may be heat treated, quenched and tempered but the cost for so doing is generally not worth the result.
Frequently Asked Questions (FAQ)
What is the carbon content of C15 steel?
C15 is a plain carbon steel with a nominal carbon content of 0.15%.
What are the typical applications for C15 steel?
Due to its properties as a low carbon steel, C15 is commonly used for manufacturing cold headed fasteners and bolts.
Can C15 steel be welded?
Yes, C15 steel can be easily welded using all standard welding techniques.
Does C15 steel resist corrosion?
No. C15 is a plain carbon steel and does not possess corrosion resistance. It will rust if it is not protected.
What is the machinability rating of C15 steel?
C15 steel has a machinability rating of 55% compared to AISI 1112 carbon steel, which is used as the 100% machinable reference. It performs particularly well in cold drawn or cold worked conditions.
How is stress relieving performed on C15 steel?
Stress relieving is performed by heating the steel to approximately 540°C, holding it at that temperature for 1-2 hours, and then cooling it in air to reduce distortion during subsequent heat treatments.
