What is EN8 Grade Steel?
En8 High Carbon Steel bars are made of unalloyed steel with medium carbon to have h high strength and temperature resistance. It is suitable for applications that do not need alloyed 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 has excellent surface hardness and moderate wear resistance with induction or flame hardening. Reputed suppliers offer EN 8 steel rods in the precision ground or surface ground cut as per the customers’ requirements.

What is the difference between Mild Steel and EN8 Bars?
EN 8 bars have more carbon content than mild steel to be stronger and with high-temperature resistance. While mild steel has less than 0.25%, carbon, and EN8 steel bar have carbon from 0.36 to 0.44% to have many better properties.
Compared to EN 8, mild steel is fragile and could break in high-stressed applications. It is the reason that many prefer using EN 8 steel to mild steel. Also, EN 8, with more carbon than mild steel, has more strength by solidifying through heat treatment.

What is the full form of EN8 Material?
The full form of EN 8 material is Emergency Number 8 material which is non-alloyed steel with medium carbon content. British formed the emergency numbering system to identify the many engineering steel 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 steel with more carbon of 0.36 to 0.44. Hence it has high strength for applications in sectors.

What is EN8 Rod uses?
EN 8 steel having high strength and being available at affordable costs than much-alloyed steel, 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 steel 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 steel to supply flatter and straighter to be more cost-effective.
