General Information about 1040 Round Bar and 1040 Steel Bar
1040 steel bar is a standard carbon steel grade supplied in a wide variety of shapes, sizes and conditions. One common shape is 1040 round bar.
1040 round bar may also appear as:
- SAE (Society of Automotive Engineers)
- SAE 1040
- AISI (American Iron and Steel Institute)
- AISI 1040
1040 steel bar can also be characterized as a medium carbon grade and can be supplied as hot rolled, cold drawn, rough turned or turned and polished. By cold drawing 1040 bar stock, it will increase the mechanical properties, improve the size tolerance and enhance the surface. 1040 round bar can also be annealed to make the material more formable.
1040 steel bar is produced in a variety of lengths, and can also be packaged into wire rod. A common length for 1040 round bar is 20′, while certain mills have the capacity to produce longer lengths in certain diameters. A typical wire rod size is around 4,000 #.
1040 round bar is commonly used for working cold steel into a variety of components, as well as machined into cold finished parts. 1040 steel bar may also be hot or cold forged to produce a wide range of finished products. Some applications include fasteners, crankshafts, coupling & cold headed parts. 1040 round bar is often used in general engineering applications where better strength than that of a more mild carbon grade is required.
1040 round bar has a chemical composition that consists of carbon, .15/.30, manganese, .60/.90, phosphorus, .04 (max.), sulfur .05 (max.) and silicon .15/.30.
