Description
EN15AM – Bright Bar Overview:
EN15AM is a free-cutting, carbon steel alloy designed for high machinability, making it ideal for use in CNC and automatic machines in mass production. It contains carbon as the main alloying element, along with other elements such as silicon, manganese, and trace amounts of molybdenum, chromium, nickel, copper, and aluminum. The addition of sulfur improves machinability, while elements like phosphorus and sulfur may also be present as impurities. This steel is commonly used in applications requiring good strength and hardness, particularly in automotive and general engineering sectors.
