Treatment with heat:
Each EN31 component will require a different heat treatment temperature, cooling rate, and soaking time. There are also other factors to consider during the heat treatment process, such as the type of furnace, the quenching medium, and the transfer facilities for the work piece.
Developing hardness:
Slowly heat to a temperature of 800-820°C for hardening. Keep soaking until thoroughly soaked. You must give this soaking and oil quenching plenty of time.
The tempering process:
Generally, tools should be tempered between 150°C and 300°C depending on their purpose. After selecting the temperature, soak the material for at least one hour per 25mm of thickness. As air cools, it slows down.
| Temperature [°C] | 150 | 200 | 250 | 300 |

| Thermal conductivity (typical steel) | 46.6 W/mk | 323 BTU in/hr.ft².°F |
Properties of forging:
Start forging at 1000-1050°C and heat slowly. Ensure the steel is thoroughly soaked through at the forging temperature. Forge at 850°C or higher and reheat as necessary. Forged EN31 steel should be cooled slowly, preferably in a furnace, after forging.
Reliving stress:
Prior to hardening, stress relief will be beneficial when parts will be heavily machined. The EN31 should be heated carefully to 700°C, soaked well, and allowed to cool in the air.
Normative:
How to Anneal:
EN31 is usually supplied annealed and machinable. A re-annealing is only required if the steel has been forged or hardened. In order to anneal EN31 steel, slowly heat it to 800-810°C, soak it well, and allow it to cool in the furnace.

Ability to machine:
Despite its potential importance in the automotive industry, EN31 Round Barl is a challenging alloy to machine because it exhibits outstanding surface characteristics but is dimensionally inaccurate. In the present study, wire electrical discharge machining (WEDM) of EN31 Round Bar is examined to gain a fundamental understanding of the effects of the process parameters on the micro-scale characteristics of machined surfaces.
In order to understand the influence of WEDM parameters on edge roughness, kerf width, and cutting rate, WEDM parameters such as pulse on-time, servo voltage, wire feed and wire tension are grouped in an efficient way. Low pulse on-time and low servo voltage decreased kerf width and edge roughness in the current study. On the other hand, cutting rate decreased with pulse on-time, but increased with servo voltage. There were diverse effects of wire tension and wire feed on response parameters. Unlike edge roughness, kerf width varied directly with wire feed, corresponding to lower wire tension.
EN31 Round Bars Available in a Variety of Sizes
The following sizes are available: 16mm, 18mm, 20mm, 22mm, 23.5mm, 24mm, 25mm, 26mm, 27mm, 28mm, 30mm, 32mm, 34mm, 35mm, 36mm, 37mm, 38mm, 40mm, 42mm, 45mm, 46.5mm, 47mm, 50mm, 51mm,53mm, 56mm, 60mm, 63mm, 65mm, 70mm, 75mm, 78mm, 80mm, 85mm, 90
