| 1018 | A low-carbon steel with manganese added to produce a harder more uniform case when carburized. It has higher mechanical properties and better machining characteristics than other low-carbon steels. Most cold finished bars are produced by cold drawing. | X | X | X |
| 1045 | Medium-carbon steel centerless ground and polished to the highest attainable concentricity, surface perfection, straightness, and overall accuracy. Often referred to as pump shaft or pump rod. The special straightness helps prevent vibration and wear on packings and bearings in pumps. | X | X | |
| 12L14 | Fastest machining steels available. This is essentially resulfurized, rephosphorized screw stock with lead added (Grade A). Commonly referred to by the trade name Ledloy™ | X | ||
| A-36 | Hot rolled mild-carbon steel. This material has good overall mechanical properties, is easily fabricated, and may be formed hot or cold. | X | ||
| 4140 | 4140 is excellent for tooling and maintenance applications and numerous machine component parts. The countless applications include backup and support tooling, die details, short run dies, spindles, brake dies, axles, bolts, forming rolls and other machine tool components. | X | X | X |
| 4340 | Nickel-chromium-molybdenum commercial-quality alloy steel. This steel can attain much deeper hardenability than 4100 series steel. High strength in heavy sections is possible with maximum toughness and ductility. This material has a high fatigue/tensile ratio and maintains strength, ductility, and toughness at relatively high temperatures. 4340 also has remarkable non-distorting properties for an alloy steel. | X | ||
| 5160 | Carbon-chromium spring steel. It has a high yield-to-tensile strength ratio, excellent toughness, and high ductility. Special care is taken during rolling and cooling to obtain satisfactory cold-shearing, punching, and trimming qualities. | X | ||
| 6150 | High-carbon chromium-vanadium commercial-quality alloy steel. This material attains hardness and strength that is higher than 4142. When heat treated, the material has excellent toughness, shock resistance, and wear/abrasion resistance. | X | ||
| 8620 | Chromium-nickel-molybdenum steel. This is a "triple alloy" carburizing steel. The nickel provides good toughness and ductibility, chromium and molybdenum contribute increased hardness penetration and wear resistance. The alloy content permits hardening to a strong, tough core, with high-case hardness. The grade is reality carburized, has excellent machinability, and responds well to polished operations. The grade is available with lead added for improved machinability. Due to decreased ductibility, leaded grades should not be used in applications over 400° F. | X | ||
| 52100 | High-carbon, high-chromium, aircraft quality bearing steel. This material develops high hardness, and exceptional resistance to wear and abrasion. In smaller sections it has high compressive strength. Furnished in the spheroidized annealed condition in order to provide the best possible machinability. | X |
