AISI 4145

AISI 4145 is a medium-carbon alloy steel known for its strength, toughness, and wear resistance. It contains approximately 0.40-0.50% carbon, along with 0.80-1.10% chromium, enhancing its hardenability and resistance to deformation. This grade is commonly used in the manufacture of components such as shafts, gears, and large-diameter pipes, especially in the oil and gas industry. AISI 4145 can be heat-treated to achieve a wide range of mechanical properties, making it versatile for various applications. Its good machinability and weldability, coupled with its strength, make it a preferred choice for demanding engineering applications.
