EN8 Carbon Steel stands as a prominent member of the medium carbon and medium tensile steel family, recognized for its superior strength compared to mild steel. This through-hardening medium carbon steel offers a robust combination of mechanical properties, making it a preferred choice in various industrial applications. At its core, EN8 is celebrated for its machinability under diverse conditions.

EN8 carbon steel strikes a balance between carbon content and tensile strength, making it an ideal choice for applications requiring enhanced strength without compromising on machinability.

One of the standout features of EN8 is its exceptional machinability. This attribute allows for ease of machining in any condition, contributing to efficient manufacturing processes.

While EN8 is commonly used in its untreated condition, it has the capability to undergo surface hardening through induction processes. This enhances wear resistance, extending the lifespan of components in demanding applications.

EN8 steel, in its heat-treated forms, exhibits homogenous metallurgical structures. This consistency not only contributes to its mechanical strength but also ensures predictable and reliable machining properties.

EN8 steel holds a significant position within the BS 970-1955 specification, a standard dedicated to wrought steel for mechanical and allied engineering purposes. As part of this esteemed standard, EN8 is renowned for its mechanical properties, making it a pivotal steel grade in various industrial applications.

Within the framework of BS 970-1955, EN8 is part of a family of steel grades, each designed for specific applications. Other notable grades include EN9, EN19, EN24, EN36, and more. Notably, the most equivalent contemporary grade is 080M40 steel in BS 970-1991, underlining the enduring relevance and recognition of EN8 steel.

EN8 Round Bar stands out as a pinnacle in medium carbon steel, offering impressive ductile strength compared to standard mild steel. This steel grade is exceptionally well-suited for a broad spectrum of manufacturing applications that demand advanced strength. At [Your Company Name], we present EN8 steel – a reliable choice for crafting tubes, studs, bolts, linking rods, screws, rollers, and more.

EN8 bright bar, a medium-strength mild steel, serves general manufacturing purposes that demand steel with higher strength than mild steel. While superior to EN3, it maintains a balance between strength and machinability. Common uses include tubes, studs, screws, and keys.

EN8 Bright Mild Steel Round stands as a medium-power steel, meticulously crafted for overall engineering applications demanding higher strength than conventional mild steel. The EN8 Bright Square Bar, shaped through cold over and cold drawn processes, exemplifies precision and strength. The EN8 grade, characterized by its purity and medium carbon composition, attains extraordinary strength levels compared to normal Bright Mild Steel, courtesy of meticulous flask mechanical rolling.

For your convenience, we offer a range of EN8 products, including bright square bars and threaded bars, with competitive prices. With years of expertise in supplying EN8 products in India, we ensure quality and reliability in every transaction.
