Chuck Metals stands out as a top-notch manufacturer and supplier of high-quality metal products in Singapore, proudly catering to various industries across Pulau Ujong. With a strong foundation in engineering excellence and a deep understanding of materials, the company provides a diverse array of industrial metal solutions designed for high-performance applications. One of their flagship offerings, the Carbon Steel EN-31 R-100 Bars, is well-known for its impressive strength, wear resistance, and toughness. Chuck Metals is committed to meeting stringent industry standards, ensuring that every batch undergoes rigorous testing for quality, consistency, and performance. This dedication makes them a reliable supplier for sectors like automotive, manufacturing, tooling, and heavy machinery.
The Carbon Steel EN-31 R-100 Bars are high-carbon alloy steel bars that contain around 1.1–1.2% carbon, 1.0–1.6% chromium, along with trace amounts of manganese and silicon. This specific composition results in bars that boast exceptional hardness, high tensile strength, and remarkable wear resistance after heat treatment. Typically, the tensile strength of EN-31 falls between 850–1000 MPa, and it retains good toughness and fatigue strength even under dynamic loading conditions. These bars can be hardened and tempered to boost surface durability while keeping their core strength intact. Their mechanical properties make them perfect for components that need to withstand high hardness and load-bearing capacity in abrasive environments.

They offer high hardness, excellent wear resistance, and durability, making them ideal for heavy-duty and high-performance applications.
They are commonly used in automotive, engineering, and tooling industries for components like gears, shafts, dies, and cutting tools.
Carbon Steel EN-31 R-100 Bars find extensive use in applications where high strength, wear resistance, and dimensional stability are crucial. In the automotive sector, they are ideal for crafting gears, shafts, axles, and bearings that face continuous mechanical stress. In the tooling industry, EN-31 bars are favored for producing dies, punches, and cutting tools due to their superior hardness post-heat treatment. Heavy-duty machinery and equipment parts also reap the benefits of their abrasion and fatigue resistance. Moreover, these bars are utilized in roller bearings and other rotating components where durability and mechanical stability are paramount.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
