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 background in engineering and material knowledge, the company provides an extensive array of industrial metal solutions designed for high-performance needs. 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 rigorous industry standards, ensuring that each batch undergoes thorough 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 unique blend results in bars that boast exceptional hardness, high tensile strength, and outstanding 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.
