Sahil Metals, located in Riyadh, Saudi Arabia, has established itself as a reliable manufacturer and supplier of top-notch carbon steel products designed for precision and durability. One of their standout offerings is the **Carbon Steel EN‑351 Bars**, a case-hardening steel that finds its place in various engineering sectors driven by demand. These bars are delivered in their as-rolled state and cater to industries like power generation, chemical processing, and heavy machinery manufacturing across Saudi Arabia and the GCC, all while adhering to strict quality standards.
When it comes to composition, **Carbon Steel EN‑351 Bars** feature a meticulously controlled blend: carbon content ranges from **0.10–0.20%**, manganese from **0.60–1.00%**, silicon between **0.15–0.35%**, and both sulfur and phosphorus are limited to a maximum of **0.035%**. Additionally, chromium is present at **0.40–0.80%**, and nickel at **0.60–1.0%** ([TK Steels][1]). In their annealed, cold-rolled state, these bars showcase a moderate hardness of **170 to 200 BHN**, making them perfect for applications that require case hardening along with core toughness ([TK Steels][1]).

Carbon Steel EN-351 Bar is commonly used in construction, structural applications, and manufacturing machinery components, providing strength, durability, and resistance to wear, corrosion, and impact for various industrial uses.
The available thicknesses for Carbon Steel EN-351 Bars typically range from 5mm to 250mm, depending on the supplier and specific requirements, with custom thicknesses available upon request.
Carbon Steel EN-351 bar has high strength, good toughness, and moderate corrosion resistance. It exhibits good weldability, hardness, and machinability, with tensile strength ranging from 560 to 700 MPa.
The **Applications** of EN‑351 Bars are diverse, including the production of high-wear components like gears, shafts, pins, and small mechanical parts that benefit from a hard exterior and a tough core. Their well-balanced machinability and impressive hardenability make them particularly well-suited for components that undergo through-hardening and case-hardening, especially those facing cyclic or impact loads.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
Sahil Metals is a leading manufacturer, supplier, and exporter of high-quality bars, rods, and forgings, catering to various industries in Riyadh, Saudi Arabia
