EN 1A Steel Supplier in India | High-Quality Free-Cutting Steel
Introduction to EN 1A Steel
EN 1A steel is a popular low-carbon, free-cutting steel renowned for its exceptional machinability and ability to produce a smooth, clean surface finish. This grade is specifically engineered for high-speed machining operations on automatic and CNC lathes, making it the material of choice for mass-produced, non-critical components. Its chemistry allows for excellent chip-breaking properties, which significantly increases production efficiency and extends tool life. At Jupiter Steels, based in Delhi, we are a trusted stockist and supplier of EN 1A steel, providing certified material to businesses throughout India, including industrial hubs in Manesar, Haryana, and beyond.
Chemical Composition of EN 1A Steel
The outstanding performance of EN 1A steel is a direct result of its carefully controlled chemistry. The key elements and their typical weight percentages are:
- Carbon (C): Max 0.09%
- Manganese (Mn): 0.90 – 1.20%
- Sulfur (S): 0.23 – 0.33%
- Phosphorus (P): 0.05 – 0.10%
Functioning and Reasoning of Chemical Elements
- High Sulfur (S) & Phosphorus (P): The elevated content of sulfur and phosphorus is the core reason for EN 1A steel‘s superior machinability. Sulfur forms manganese sulfide inclusions which act as chip breakers, while phosphorus promotes brittleness. Together, they allow for easy formation of small, manageable chips, which prevents tool clogging and allows for faster machining speeds.
- Low Carbon (C): The very low carbon content ensures the steel remains soft and ductile, making it easy to form and cut.
Hardness, Properties, and Applications of EN 1A
Hardness
In its as-drawn condition, EN 1A steel is a soft material with a hardness typically in the range of 120-150 HB. It is not typically heat-treated to achieve higher hardness.
Properties
- Exceptional Machinability: Its primary advantage is its ability to be machined at very high speeds with minimal tool wear.
- Good Weldability: The low carbon content makes it easy to weld, although the high sulfur content can affect weld quality.
- Smooth Surface Finish: It consistently provides a high-quality surface finish directly from the machining process.
- Ductility and Formability: It is a soft material, making it easy to bend and form.
Applications
EN 1A steel is extensively used for non-critical, high-volume production of components. Key applications include:
- Nuts and Bolts
- Studs and Threaded Components
- Screws and Pins
- General engineering components that require high-speed machining and do not need high strength.

EN 1A Steel FAQ Section
Q1: What is EN 1A steel used for?
A: EN 1A steel is primarily used for high-speed machining applications to produce non-critical components like screws, nuts, and bolts.
Q2: Is EN 1A a high-strength steel?
A: No, EN 1A steel is a low-carbon, low-strength steel. Its main benefit is its exceptional machinability, not its strength.
Q3: Can EN 1A be heat-treated?
A: Due to its very low carbon content, EN 1A steel cannot be hardened by conventional heat treatment methods.
