1. Introduction to AISI 1050 Steel

AISI 1050 is a high carbon steel belonging to the SAE-AISI system. This classification system, developed by the Society of Automotive Engineers (SAE) and the American Iron and Steel Institute (AISI), uses a four-digit numbering system to represent various steel grades. AISI 1050 steel is designated as 1050 because it contains approximately 0.50% carbon. This medium carbon steel is known for its good mechanical properties, particularly its strength, toughness, and ductility.
