Differences Between 300 and 400 Series Stainless Steel
Differences Between 300 and 400 Series Stainless Steel
Crystal Structure and Magnetism
- 300 Series: This stainless steel has an austenitic crystal structure and is non-magnetic.
- 400 Series: It features a ferritic crystal structure and is magnetic.
Suitability for Food and Pharmaceutical Applications
- 400 Series: Ideal for environments where magnetic detection is needed. Magnetic sensors can identify loose steel parts at the end of the production line, ensuring safety.
- 300 Series: Commonly used for tubing in food and pharmaceutical applications. Tubing does not typically involve loose parts, making it a reliable choice despite being non-magnetic.
In summary, the 400 series is preferred for applications requiring magnetic detection, while the 300 series is better suited for secure, fixed components like tubing.
