FAQs
Q: How does 201 stainless steel compare to 304?
A: 201 has lower nickel content (3.5–5.5% vs. 8–10% in 304), making it cheaper but less corrosion-resistant. Ideal for indoor or low-moisture environments.
Q: Is 201 stainless steel magnetic?
A: No—it’s austenitic and non-magnetic, unlike 430 or 410 grades.
Q: Can it be used outdoors?
A: Yes, but it may require periodic maintenance in humid or coastal areas. For harsh environments, consider 316 grade.
