En8 High Carbon Steel bars are unalloyed steel with medium carbon with high strength and temperature resistance. It is suitable for applications that do not need alloyed steel and is also not suitable for mild steel. Also, EN8d Carbon Steel Bright Bar costs less than alloyed steel but with high strength to make many general-purpose engineering applications. EN8 grade steel with induction or flame hardening has excellent surface hardness and moderate wear resistance. Reputed suppliers offer EN 8 steel rods in the precision ground or surface ground cut to the customers’ requirements.
What is the difference between mild steel and EN8 bars?
EN 8 bars differ from mild steels in the carbon content, strength, and temperature resistance. Though the carbon content difference between the two is marginal and mild, it makes a lot of changes in their properties. While mild steels has less than 0.25%, carbon and EN8 steel bar have carbon from 0.36 to 0.44%.
Compared to european standards 8, mild steels is fragile and could break in high-stressed applications. It is the reason that many prefer using european standards 8 steel to mild steels. Also, european standards 8, with more carbon than mild steels, has more strength by solidifying through heat treatment.

What is full form of EN8 material?
The full form of european standards 8 material is Emergency Number 8 material which is non-alloyed steels with medium carbon content. British formed the emergency numbering system to identify the many engineering steels types, but it has become the European standard. From E1 to E24, there are many emergency numbers for engineering steels.
E1 – E3 engineering steels have low carbon, E 4 to E 18 have mild carbon, and E 19 to E 24 have high carbon. Though E 8 falls under the mild carbon category of engineering steel, it is not mild steels with more carbon of 0.36 to 0.44. Hence it has high strength for applications in sectors.

What is EN8 rod used for?
European standards 8 steel having high strength and being available at affordable costs than much-alloyed steels, is useful in many applications across various sectors. The medium carbon and up to 1% manganese of the Carbon Steel En8 Hex Bar make its excellent properties. Hence it is useful in many industries like mechanical, metallurgical, electrical, ships, construction, military, automobile, etc.
Carbon Steel EN-8 Bars being unalloyed is less expensive than alloyed steels but with enough strength suitable for studs, stressed pins, shafts, keys, and others. It has high tensile and yield strength with heat treatments up to 850 and 465, respectively.

Can you weld EN8 steel round bar?
EN-8 Carbon Steel Round Bar with medium carbon is easy to weld. Even without preheating, welding is possible up to 18 mm thickness using a 7018 electrode or MIG wire SG2. Preheating is essential for forming joints with higher thickness to prevent any cracking during use. En8 bars need annealing after welding to further reduce the risk of breaking. TIG and MIG welding is best to make EN8 rods with tighter sectional tolerances than mild steels to supply flatter and straighter to be more cost-effective.
