Engineering steel is a high-performance steel that excels in construction, mechanical, automotive and aerospace applications by providing superior strength, durability, resistance to wear, corrosion and temperature extremes. It is available in different types of carbon, alloy and tool steels, including 4140, 4340, 8620 and 1045, and undergoes special treatments such as quenching, tempering and case hardening for improved performance. It is ideal for gears, shafts, bearings and structural components. Its machinability, weldability and fatigue resistance make it the preferred choice for high stress environments.
