Principal Design Features |
CS 1010 is a plain carbon steel with a nominal 0.10% 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 1010, are used for applications such as cold headed fasteners and bolts. |
Machinability |
Machinability of 1010 steel is fairly good, especially in the cold drawn or cold worked condition. Based upon carbon steel 1112 as a reference that is considered 100% machinable (easily machined) the 1010 steel has a rating of 55%. |
Forming |
Formability of 1010 steel is good. The alloy has good ductility and is readily formed by conventional means. |
Welding |
1010 steel may be welded by all of the standard welding techniques. |
Heat Treatment |
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. |
Forging |
Forging may be done in the range of 2300 F down to 1800 F. |
Hot Working |
The alloy may be hot worked in the range of 900 F to 200 F. |
Cold Working |
1010 is easily cold worked by traditional means. Following severe cold working a stress relief, or full, anneal should be performed. |
Annealing |
A full anneal is done at 1600 to 1800 F followed by slow cooling in the furnace. A stress relief anneal may be done at 1000 F and slow cooled. In the full annealed condition 1010 steel has a tensile strength of about 45 ksi. |
Aging |
Not applicable. |
Tempering |
Tempering may be done, after hardening, at 600 to 1100 F depending upon the strength level desired. Tempering at 1000 F will give a tensile strength on the order of 75 ksi. |
Hardening |
Hardens by cold working or heat treatment. See "Heat Treatment" and "Tempering". |
