Why Engineers Choose EN1.4310 Stainless Steel Foil Over 304

When selecting a stainless steel foil for technical applications, EN1.4310—also known as SUS301—offers some clear advantages over the more common 304 grade, especially in scenarios where mechanical strength and cold workability are major considerations.

Key Differences and Advantages

Unlike 304, EN1.4310 contains less nickel and chromium, but is enriched with nitrogen, which significantly improves its ability to be strengthened through cold rolling. This allows it to reach much higher strength levels without the need for heat treatment, which can simplify production processes and reduce costs.

Although 304 stainless steel is known for its excellent corrosion resistance, EN1.4310 still provides reliable protection against rust in atmospheric environments, making it suitable for most general-purpose and industrial applications. While it may not match 304 in aggressive chemical exposure, its resistance is more than sufficient for many transportation and mechanical uses.

Another key benefit is its lightweight nature. In applications like trams and other transport systems, using EN1.4310 helps reduce overall vehicle weight while maintaining structural performance—an important factor in improving energy efficiency and speed.

Ideal Use Cases

EN1.4310 is well-suited to applications that involve:

- Frequent mechanical stress, where its fatigue resistance is a major advantage

- High-temperature environments, where strength retention is crucial

- Precision forming, such as in electronic connectors, spring components, and structural fasteners

For engineers and manufacturers looking for a strong, formable, and cost-effective stainless steel solution, EN1.4310 offers a well-rounded option that performs in both structural and functional roles.
