Sri Sakthi Steels

EN1A steel is a low carbon-manganese free cutting steel, known for its machinability. It typically has a chemical composition that includes carbon (0.07-0.15%), manganese (0.80-1.20%), silicon (0.10% max), phosphorus (0.070% max), and sulfur (0.20-0.30%), as per BS970:1955 .It can also be leaded (EN1APb) for further enhanced machinability. EN1A Chemical Composition (BS970:1955):

• Carbon (C): 0.07-0.15%
• Silicon (Si): 0.10% max
• Manganese (Mn): 0.80-1.20%
• Phosphorus (P): 0.070% max
• Sulfur (S): 0.20-0.30% 

EN1A Leaded (EN1APb) Chemical Composition: 

• Lead (Pb): 0.15-0.35%
• Other Elements: Similar to non-leaded EN1A, but with the addition of lead. 

Key Features and Applications:

• Machinability: Excellent machinability due to low carbon content and sulfur and phosphorus. 
• Free Cutting: Designed for rapid production of components on automatic lathes.
