EN Steel, also known as European Norm steel, is widely recognized for its superior mechanical properties, precision composition, and consistent performance across various industrial applications. The ES Series encompasses a broad range of carbon, alloy, and tool steels that are engineered to meet stringent international standards. These steels offer excellent machinability, high tensile strength, and wear resistance, making them ideal for components in automotive, engineering, construction, and heavy machinery sectors. At Nemi Steel & Alloys Industries, we supply high-quality EN series steels in multiple grades and forms, ensuring tailor-made solutions for diverse project requirements.
EN series steels are high-quality carbon and alloy steels designed for applications requiring precise mechanical properties and durability. For example, EN8 Steel is a medium strength steel with good tensile strength, used widely in automotive components, shafts, and stressed parts. For higher strength and toughness, EN24 Steel is preferred, especially in high-performance applications such as gears, bolts, and aerospace components. EN19 offers a balance of strength and shock resistance, while EN31, with its high carbon and chromium content, is known for excellent wear resistance and hardness.
There are various EN steel grades suited for specific industrial needs, each conforming to different chemical compositions and mechanical standards. These steels can be supplied in rounds, flats, squares, and custom-forged shapes. Heat treatment, surface finishing, and machining compatibility also differ across grades. Depending on application and required performance, EN series steels can be normalized, annealed, or quenched and tempered. Please contact us for detailed specifications, available sizes, and pricing for the complete EN Steel product range.

EN8 also know as 080M40. Unalloyed medium carbon steel. EN8 is a medium strength steel, good tensile strength. Suitable for shafts, stressed pins, studs, keys etc. AISI 1040. Available as normalized or rolled. EN8 is supplied as round drawn/turned, round hot rolled, hexagon, square, flats and plate. EN8 is usually supplied untreated but can be supplied to order in the normalized or finally heat treated (quenched and tempered to ”Q” or “R”properties for limiting ruling sections up to 63mm), which is adequate for a wide range of applications. Please refer to our selection guide for comparisons. EN8 is a very popular grade of through-hardening medium carbon steel, which is readily machinable in any condition. (Refer to our machinability guide). EN8 is suitable for the manufacture of parts such as general-purpose axles and shafts, gears, bolts and studs. It can be further surface-hardened typically to 50-55 HRC by induction processes, producing components with enhanced wear resistance. For such applications the use of EN8D (080A42) is advisable. It is also available in a free-machining version, EN8M (212A42) EN8 in its heat treated forms possesses good homogenous metallurgical structures, giving consistent machining properties. Good heat treatment results on sections larger than 63mm may still be achievable, but it should be noted that a fall-off in mechanical properties would be apparent approaching the centre of the bar. It is therefore recommended that larger sizes of EN8 are supplied in the untreated condition, and that any heat treatment is carried out after initial stock removal. This should achieve better mechanical properties towards the core.

Vishal Steel Industries is the leading Supplier & Stockiest of EN353 Steels.
EN 353 steel has carbon content material of 0.17 % & probably the most usual form of steel, because the carbon content material raises, the material becomes tougher & harder. It's observed that the hardness & wear resistance of the EN 353 steels elevated after the warmness therapy & the micro structure is exchange from ferrite to marten website.
This grade is in general used for a lot of automobiles functions comparable to heavy duty tools, shaft, pinion, cam shafts and gudgeon pins.
Steel Properties:
En 353 steel has a carbon content of 0.17% and the commonest form of steel as it provides material properties that are acceptable for several automobile applications such as significant duty gear, shaft, pinion, camshafts and gudgeon pins. It’s neither outwardly brittle nor ductile due to its lower carbon content and lower hardness. Because the carbon content will increase, the metal becomes more durable and stronger.
