DESCRIPTION
M303 EXTRA Stainless Steel is a type of stainless steel known for its excellent machinability, making it ideal for applications requiring high precision and good surface finish. Based on the 303 stainless steel standard, this variant features a special alloy composition that enhances machinability without compromising mechanical properties or corrosion resistance.
Key Characteristics of M303 EXTRA Stainless Steel:
- Chemical Composition:
- Chromium (Cr): Around 17-19%, provides good corrosion resistance.
- Nickel (Ni): Around 8-10%, maintains the austenitic structure, enhancing strength and corrosion resistance.
- Manganese (Mn): Added to improve machinability and ductility.
- Sulfur (S): Higher content, significantly improving machinability but may slightly reduce corrosion resistance.
- Phosphorus (P): Maximum 0.20%, improves ductility and hardness.
- Physical Properties:
- Good Corrosion Resistance: Despite higher Sulfur content, M303 EXTRA retains considerable corrosion resistance in typical environments.
- Superior Machinability: With increased Sulfur content, this steel is much easier to machine compared to other stainless steels, making it ideal for high-precision and high-volume manufacturing.
- Mechanical Strength: Maintains good mechanical strength, suitable for applications requiring load-bearing capacity and durability.
- Applications:
- Precision Engineering: Used in the production of small components requiring high precision, such as shafts, screws, and other mechanical parts.
- Automation Industry: Applied in machinery parts requiring strength and wear resistance.
- Medical Devices: Utilized in surgical instruments and medical equipment due to its corrosion resistance and durability.
Manufacturing and Processing:
- Production Process: M303 EXTRA is produced through a specialized metallurgical process designed to optimize machinability without compromising other material properties.
- Fabrication: This steel can be easily machined using methods such as turning, milling, and drilling, while maintaining high precision and excellent surface finish.
