EN 1.4372 / X12CrMnNiN17-7-5 is a CrMn-Ni austenitic stainless steel, commonly known as AISI 201, developed as a cost-effective alternative to AISI 304. It contains higher manganese (Mn) and nitrogen (N) in place of some nickel, which reduces cost while still maintaining austenitic structure and moderate corrosion resistance.

What is the Chemical Composition of 201 Stainless Steel?
| Element | Content (%) |
|---|---|
| Cr | 16.0 – 18.0 |
| Mn | 5.5 – 7.5 |
| Ni | 3.5 – 5.5 |
| N | ≤ 0.20 |
| C | ≤ 0.15 |
| Si | ≤ 1.0 |
| P | ≤ 0.06 |
| S | ≤ 0.03 |
The reduced nickel and increased manganese content lower cost but also affect corrosion resistance and ductility compared to 304.

🔹 Is 201 stainless steel rust-proof?
201 has lower corrosion resistance than 304 or 316. It may rust in humid or chloride-rich environments (e.g. coastal areas) over time. It's suitable for indoor or low-moisture environments.
🔹 Is 1.4372 magnetic?
Like most austenitic stainless steels, 1.4372 is non-magnetic in annealed condition but can become slightly magnetic after cold deformation.
