Why is 1045 steel round bar referred to as excellent grade steel
1045 steel bar is a high-quality carbon structural steel, which not only has low price, good plasticity and toughness, but also has high strength. It is suitable for cutting processing and is widely used in the production of small section quenched and tempered parts that bear large loads, as well as large normalized parts with low stress.
