Alloy Steel AISI 4145 Bars are among the premium alloy steel solutions that Luke Steel, a leading manufacturer and supplier with headquarters in Houstan, United Arab Emirates, is known for providing. In heavy-duty industrial applications, where high strength, toughness, and fatigue resistance are crucial, these bars are designed to perform exceptionally well. Luke Steel, which is dedicated to quality and accuracy, provides AISI 4145 bars in a range of sizes and finishes to satisfy a wide range of client demands in industries like manufacturing, aerospace, defence, and oil and gas in the Middle East and abroad.
Carbon (0.43–0.48%), chromium (0.75–1.20%), manganese, molybdenum (0.15–0.25%), and silicon make up Alloy Steel AISI 4145 Bars. Excellent mechanical qualities, such as a yield strength of about 690 MPa and a tensile strength of 965–1035 MPa, are achieved by heat treating this alloy. The bars have exceptional fatigue resistance, impact toughness, and hardenability. They are appropriate for intricate manufacturing processes due to their exceptional machinability and weldability. Long-lasting and reliable performance in demanding environments is ensured by AISI 4145’s ability to withstand high temperatures and stress.
