Low Alloy Steel Materials

Enhanced strength and toughness for demanding applications

What are Low Alloy Steels?

Low alloy steels are iron-based materials containing small amounts of alloying elements (typically 1-5% by weight) such as chromium, nickel, molybdenum, manganese, silicon, and vanadium to enhance specific properties beyond those of carbon steels.

These carefully engineered compositions provide an optimal balance of strength, toughness, hardenability, and wear resistance, making them ideal for applications requiring superior mechanical properties under demanding conditions.

At Howco, we offer a comprehensive range of low alloy steel grades specifically selected for their ability to perform in critical applications in the energy sector, where reliability and performance are paramount.
