Norman Nickel Alloys stands out as a top-notch manufacturer and supplier of high-quality Alloy Steel AISI 4140 Bars right in Kuala Lumpur, Malaysia. We take pride in offering products that are designed for exceptional strength, toughness, and durability. Our AISI 4140 bars are crafted with precision to meet rigorous international standards, ensuring they perform reliably even in the toughest industrial settings. These bars find their way into various sectors, including automotive, aerospace, oil and gas, and heavy engineering, making them perfect for components that demand outstanding mechanical properties, high wear resistance, and a long service life, even under intense stress and fluctuating operational conditions.
Alloy Steel AISI 4140 Bars are made from chromium-molybdenum alloy steels, featuring about 0.38–0.43% carbon, 0.75–1.00% manganese, 0.80–1.10% chromium, and 0.15–0.25% molybdenum. This specific blend strikes a great balance between strength, hardness, and toughness. Typically, they showcase a tensile strength ranging from 655–1080 MPa and a yield strength of 415–760 MPa, along with impressive impact resistance. Plus, these bars can be heat-treated to boost their mechanical performance, making them perfect for high-stress applications that require both durability and precision.
