Chuck Metals stands out as a trusted manufacturer and supplier of Alloy Steel AISI 4145 Bars right in Singapore, Pulau Ujong. They offer top-notch alloy bars that are built for outstanding strength and performance, even in the toughest conditions. These bars are well-known for their impressive toughness, fatigue resistance, and hardenability, making them perfect for heavy-duty tasks. Chuck Metals provides AISI 4145 bars in a variety of sizes, finishes, and heat treatments to align with specific industry standards. With a strong commitment to quality and precision, the company caters to a wide array of sectors, including oil and gas, power generation, and machinery manufacturing.
The composition of Alloy Steel AISI 4145 Bars mainly includes carbon (0.43–0.48%), chromium (0.75–1.20%), manganese (0.65–0.95%), molybdenum (0.15–0.25%), and silicon (0.15–0.35%), along with trace elements that boost its strength and toughness. The mechanical properties are impressive, featuring a tensile strength of about 850–1000 MPa, yield strength around 650–850 MPa, elongation of 18–22%, and remarkable impact resistance, especially when heat-treated. This makes them ideal for heavy-load applications.
