1215MS Non-Alloy Bar Steel is a low carbon, non-alloy steel known for its excellent machinability. This steel is commonly used in applications requiring high-speed machining, such as turning, milling, and drilling.

Key Characteristics of 1215MS Non-Alloy Bar Steel:

- Chemical Composition:
- Carbon (C): Approximately 0.09 - 0.13%
- Manganese (Mn): Approximately 0.75 - 1.05%
- Phosphorus (P): Max 0.04%
- Sulfur (S): Approximately 0.26 - 0.35%
- Lead (Pb): Small amounts may be added to improve machinability
- Iron (Fe): The remainder

- Physical Properties:
- Tensile Strength: Approximately 350 - 450 MPa
- Elongation: Approximately 10 - 20%
- Machinability: Excellent, easily machined with cutting tools, no heat treatment required

- Applications:
- Precision Machining: Widely used in components requiring high precision, such as shafts, screws, bolts, and other small parts
- Mass Production: Suitable for mass production in industries that demand quick machining and low costs
- Other Mechanical Applications: Used in machinery parts that do not require high strength but need good machinability

- Shape and Size:
- 1215MS is typically supplied in round, square, or rectangular bars depending on specific application requirements

Manufacturing and Processing:
- 1215MS is produced through hot rolling or cold rolling processes, and can be easily machined using traditional mechanical methods. Due to its high sulfur content, this steel offers excellent machinability, reducing tool wear and enhancing production efficiency.
