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 & Heat Treatment
Heat to 850-950 oC, cool slowly. This will produce a hardness of 90-100 HB.
Stress relieving to remove machining stresses should be carried out by heating to approx. 540 oC, holding for 1-2 hours at heat, followed by air cooling. This operation is performed to reduce distortion during heat treatment.
Hot forming temperature: 1200-950 oC.
Machinability of C15 steel is fairly good, especially in the cold drawn or cold worked condition. Based upon carbon steel AISI 1112 as a reference that is considered 100% machinable (easily machined) the C15 steel has a rating of 55%.
This is a plain carbon steel and has no corrosion resistance. It will rust unless protected.
C15 steel may be welded by all of the standard welding techniques.
C15 is easily cold worked by traditional means. Following severe cold working a stress relief, or full, anneal should be performed.
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
What is C15 steel and what are its key characteristics?
C15 is a plain carbon steel with a nominal 0.15% carbon content. It is characterized as a relatively low strength steel that can be quenched and tempered to increase its strength.
What are the primary applications of C15 carbon steel?
C15 low carbon steel is commonly used for manufacturing cold headed fasteners, bolts, and other similar applications where high strength is not the primary requirement.
How machinable is C15 steel?
The machinability of C15 steel is fairly good, particularly in cold drawn or cold worked conditions. It has a machinability rating of 55% when compared to the reference carbon steel AISI 1112 (which is rated at 100%).
Does C15 steel offer any corrosion resistance?
No, C15 is a plain carbon steel and does not possess corrosion resistance. It will rust if it is not properly protected with coatings or other protective measures.
What are the recommended temperature ranges for heat treating and forging C15?
For soft annealing, heat the steel to 850-950 °C and cool slowly. For stress relieving, heat to approximately 540 °C. The hot forming/forging temperature range is 1200-950 °C.
Can C15 steel be welded and cold worked?
Yes, C15 steel can be easily welded using all standard welding techniques. It is also easily cold worked by traditional methods, though a stress relief or full anneal is recommended following severe cold working.
