EN31 Steel
Onyx Steel and Engineering Llp is leading EN31 Steel Suppliers in Pune, we are trusted Dealers, Wholesaler & Stockiest in Pune, we give commitment of quality consistency and customer satisfaction, we have developed an experienced firm in the field of steel trading and supply. Since 1988, we guarantee that all materials are sourced to be tested and delivered to meet industrial requirements and are guaranteed to perform well in client applications. Our EN31 Steel functions by giving the material a deep level of hardness after heat treatment; improving the wear resistance and load carrying abilities of the material.
Our EN31 Steel is widely used in automotive components, gear manufacturing, shaft applications, bearing applications and industrial applications requiring strength and precision. We provide variety of precision engineering wear-resistant components with high hardness, such as die making machine parts, were also widely used in the manufacture of tools. We have superior mechanical properties and can be used in mechanical parts application in aerospace, railway, hydraulic system, and heavy engineering equipment.
Our quality steel is made available for manufacturing and engineering purposes. As we are EN31 Steel dealers in Pune, We get harder after heat treatment, ensuring industries can produce materials without getting them stuck for lack of it, while also becoming more durable, for instance through precision components, after processes such as hardening and tempering.
EN31 Steel is a high carbon alloy steel which is used for a broad range of applications where surface hardness and excellent wear properties are required. It is widely used in bearings, precision engineering components, and other applications. This steel grade can be used for heat treatment to enhance its mechanical properties. It is suitable for industrial applications where heavy loads and constant use are necessary.
As EN31 Steel Suppliers in Pune, we provided different types of steel bar according EN31 according to resistance which are given below.
As EN31 Steel Wholesalers in Pune, we have added below a technical sheet that provides more technical information such as:
| EN31 Steel Type / Form | Standard Processing Condition | Typical Dimensional Range | Mechanical Properties (Tensile / Hardness) | Key Engineering Advantages & Industrial Applications |
|---|---|---|---|---|
| EN31 Round Bar | Hot Rolled or Cold Finished | 8 mm to 250 mm | Tensile: 650 - 850 MPa (Annealed) Hardness: up to 64 HRC (Hardened) | High structural concentricity and uniform core toughness. Ideal for ball and roller bearings, high-stress rollers, spindle shafts, and wear plates. |
| EN31 Flat Bar | Hot Rolled / Machined | Width: 20–300 mm Thickness: 6–80 mm | Tensile: 650 - 800 MPa (Annealed) Hardness: 58 - 62 HRC (Post-HT) | Excellent dimensional stability during heat treatment. Extensively used for toolroom dies, cold punches, gauges, and high-precision machine slide rails. |
| EN31 Bright Bar | Cold Drawn / Turned & Polished | 10 mm to 100 mm | Tolerances: h9, h10, h11 Hardness: 200 - 245 HB (Annealed state) | Smooth, defect-free surface finish with high dimensional accuracy. Perfectly suited for high-speed CNC machining of fasteners, pins, and precision bushes. |
| EN31 Black Bar | Hot Rolled (Mill Finish) | 16 mm to 300 mm+ | Tolerances: Standard Mill Tolerances Hardness: 220 - 260 HB | Cost-effective raw material with an "as-rolled" rustic finish. Designed for heavy machining operations, large-scale structural gears, and base components. |
| EN31 Forged Bar | Hot Forged & Ultrasonic Tested | 100 mm to 500 mm | Toughness: Superior impact resistance Hardness: Highly uniform through-hardened | Hot forging refines the internal grain flow, drastically improving fatigue resistance. Essential for heavy-duty industrial rollers, collets, and high-load dies. |
| EN31 Annealed Steel | Spheroidize Annealed | Form-dependent | Hardness: ≤ 229 HB (Spheroidized) Machinability Rating: ~60% |
