China C15 Carbon Steel Suppliers - AISI 1015 Low Carbon Steel from Reliable Factory

C15 is a high-quality plain carbon steel with a nominal carbon content of 0.15%. Known for its low strength, this steel can be quenched and tempered to enhance its mechanical properties. In China, this type of steel is widely utilized due to its versatility and cost-effectiveness. Major applications include the production of cold headed fasteners and bolts, making it a preferred choice among manufacturers and suppliers in the industry.
Physical properties of C15 at ambient temperature include a modulus of elasticity of 210 GPa, a density of 7.85 g/cm³, and a thermal conductivity of 58.6 W/m.K. Its electric resistivity is approximately 0.11 Ohm mm²/m, and it has a specific heat capacity of 0.46 J/g.K. Additionally, the coefficient of linear thermal expansion is 10-6 °C-1, making C15 an excellent choice for various thermal applications. Whether you're a manufacturer or a supplier, consider sourcing C15 carbon steel from reputable factories in China for your production needs.

    Description & Applications

    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 Guidelines

    Soft Annealing

    Heat to 850-950oC, cool slowly. This will produce a hardness of 90-100 HB.

    Stress Relieving

    Stress relieving to remove machining stresses should be carried out by heating to approx. 540oC, holding for 1-2 hours at heat, followed by air cooling. This operation is performed to reduce distortion during heat treatment.

    Forging

    Hot forming temperature: 1200-950oC.

    Machinability

    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%.

    Corrosion Resistance

    This is a plain carbon steel and has no corrosion resistance. It will rust unless protected.

    Welding & Cold Working

    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.

    Important 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.
