About 4140 Steel Bar
4140 Steel Bar is a chromium molybdenum alloy steel characterized by high strength, high toughness, high fatigue resistance and wear resistance. 4140 Block is commonly used in the engineering and manufacturing sectors where components come under heavy load and subjected to repeated stresses and extreme operating conditions.
Types of 4140 Steel Bar
As 4140 Steel Bar Suppliers in Pune, we provided different types according to application base which are given below.
- Annealed 4140 Steel Bar - Annealed 4140 is heat treated to soften the material and to make it easier to machine. It is widely used in the fields of easy machining and forming.
- 2. Quenched and Tempered 4140 Steel Bar - Hardened and tempered to produce high tensile and toughness strength of this type. It is widely used in engineering applications of heavy duty.
- Hot Rolled 4140 Steel Bar - Hot rolled bars are rolled at high temperatures resulting in a rough surface. They are economical and they are employed if accuracy is not vital.
- Cold Drawn 4140 Steel Bar - The bars are processed at room temperature to achieve a superior surface finish and dimensional tolerances, which is known as Cold drawn bars. They have higher strength than hot rolled bars.
- Normalized 4140 Steel Bar - Normalized bars are heated and cooled to give a more uniform and refined grain structure. They offer a balance of strength, toughness and machineability.
- Forged 4140 Steel Bar - Highly strong, durable forged bars are formed under high pressure. They can be used for high stress parts such as shafts and gears.
Technical Specification of 4140 Steel Bar:
As 4140 Steel Bar Wholesalers in Pune, we have added below a technical sheet that provides more technical information such as:
| 4140 Steel Bar Type | Manufacturing Process / Condition | Typical Tensile Strength (MPa) | Typical Yield Strength (MPa) | Standard Hardness Range | Key Engineering Attributes & Industrial Applications |
|---|---|---|---|---|---|
| 1. Annealed 4140 | Furnace Cooled (Softened state) | 650 - 700 | 415 - 450 | 197 - 223 HB | Maximum Machinability. Softened state allows for complex CNC machining, deep drilling, and forming before the component undergoes final hardening. |
| 2. Quenched & Tempered (Q&T) | Hardened, Oil Quenched, Tempered | 850 - 1050 | 650 - 850 | 28 - 32 HRC (250 - 300 HB) | High Strength & Toughness. The industry standard for heavy-duty engineering. Ready to use for high-stress drive shafts, crankshafts, gears, and structural parts. |
| 3. Hot Rolled | Mill Finish (High-Temperature Rolled) | 850 - 950 | 550 - 650 | 200 - 250 HB | Economical Raw Material. Features a rough, scaled surface. Best utilized for heavy components where tight dimensional accuracy is not critical before heavy milling. |
| 4. Cold Drawn | Cold Worked at Room Temperature | 850 - 1100 | 700 - 900 | 220 - 280 HB | Precision & Finish. The drawing process induces strain hardening, increasing yield strength while providing a smooth, bright surface and tight (h9/h10) dimensional tolerances. |
| 5. Normalized | Heated & Air Cooled | 950 - 1050 | 600 - 700 | 280 - 320 HB | Structural Uniformity. Relieves internal stresses from forging or hot rolling and refines the grain structure. Offers an excellent balance of baseline toughness and machinability. |
| 6. Forged 4140 | Hot Pressed / Hammered | Depends on final Heat Treatment | Depends on final Heat Treatment | Varies | Maximized Impact Strength. The forging process aligns the internal grain flow to the shape of the part, eliminating porosity. Ideal for massive, severe-stress applications like marine shafts and large gears. |
