EN30B Chemical Composition

Heat the steel carefully to the forging temperature of 1000-1100°C, soak well. After forging, cool slowly in a furnace to 100°C maximum and anneal immediately.

To obtain the softest condition heat carefully to 630-650°C. Soak for a minimum of 2 hours, then cool in the furnace or in air. It is advisable to repeat this treatment to obtain the best machining characteristics.

Where the machining operations have been severe, we recommend stress relieving EN30B alloy steel before finish machining and hardening. Heat carefully to 630-650°C then cool in the furnace or in still air.

Heat uniformly to 810-830°C and when thoroughly soaked at this temperature cool in air or quench in oil according to mass. Hardening from neutral salt baths will help to prevent scaling or decarburization and is strongly recommended. Pre heat at 300-400°C, raise to the hardening temperature of 810-830°C, quench into salt standing at 300-320°C. Withdraw and cool in air. Alternatively, tools may be vacuum hardened. If desired, hardened and tempered tools can be cyanide hardened to give a shallow carburized case to die surfaces with increased hardness values up to Rockwell C56-60. Temper as soon as tools are hand-warm.

Re heat to the relevant tempering temperature. Soak for at least 2 hours per 25mm of ruling section. Withdraw from the furnace and cool in still air. Tempering between 275-450°C is not advised as tempering within this range will reduce the impact value.<table class="tablepress"><tbody><tr><td>Temperature [°C]</td><td>150</td><td>250</td><td>350</td><td>450</td></tr><tr><td>Hardness [HRc]</td><td>49</td><td>47</td><td>44</td><td>38</td></tr></tbody></table>

Chemical Composition of EN31 Steel

Heat slowly and begin forging at 1000-1050°C. Allow sufficient time at the forging temperature for the steel to be thoroughly soaked through. Re heat as necessary and do not forge below 850°C. After forging EN31 steel, cool slowly preferably in a furnace.

EN31 is usually supplied in the annealed and machineable condition. Re-annealing will only be necessary if the steel has been forged or hardened. To anneal, heat the EN31 steel slowly to 800-810°C, soak well and allow to cool in the furnace.

When parts are to be heavily machined, stress relieving will be beneficial prior to hardening. Heat the EN31 carefully to 700°C, soak well and allow to cool in air.

Heat slowly to the hardening temperature of 800-820°C. Maintain until thoroughly soaked through. Plenty of time must be given for this soaking and then quench in oil.

Temper according to the purpose for which the tools are required, generally between 150°C and 300°C. Soak well at the selected temperature and soak for at least one hour per 25mm of total thickness.
