En8D steel bar is a medium carbon steel grade of engineering steel
that offers greater strength and hardness as compared to the low
carbon grades. The formability and weldability of En8d are fair when
using accepted shop practices. While machinability is good, this grade
responds very well to forging and heat treating. It is one of the most
used grades of carbon steel. People requiring better properties such
as strength, etc generally go for alloy steel if En8d or equivalent
grades are not suitable.
Typical applications of En8d steel round bar include gears, shafts,
axles, bolts, studs, crane wheels, and machine parts.

EN8D can be tempered at a heat of between 550°C to 660°C
(1022°F-1220°F), heating for about 1 hour for every inch of thickness,
then cool in oil or water. Normalizing of EN8 bright mild steel takes
place at 830-860°C (1526°F-1580°F) then it is cooled in air. Quenching
in oil or water after heating to this temperature will harden the
Heat the component slowly to 820-860°C and allow it to be heated
through. Quench in oil or water.
Temper the EN8D component immediately after quenching whilst tools
still hand warm. Re-heat the EN8D component to the tempering
temperature then soak for one hour per 25 millimeters of total
thickness (2 hours minimum) Cool in air. For most applications
tempering of EN8D will be between 550-660°C.

Preheat the steel carefully, and then raise the temperature to 1050°C
for forging. Do not forge below 850°C. After forging cool slowly,
preferably in a furnace.
Normalizing of EN8D bright mild steel takes place at 830-860°C
(1526°F-1580°F) then it is cooled in air.
Heat slowly to 680-710°C, soak well. Cool slowly in the furnace.
Modern EN8D bright mild steel contains a lot less carbon than it uses
to, this means that it is possible to weld pieces up to 18mm thick
without preheating using MIG wire (SG2) or a 7018 electrode.
Over 18mm would require a pre-heat of 100°C (212°F) in order to
Anneal afterward is recommended to prevent breaking.
