1.4372 Stainless Steel Composition: Mn‑Enhanced Austenitic Grade for Cost‑Efficient Structural Applications
1.4372 (X12CrMnNiN17‑7‑5) is a manganese‑enhanced austenitic stainless steel grade specified under EN 10028‑7 and EN 10088‑2. Often regarded as an upgraded version of the 201 series, it contains 16–18% chromium, 3.5–5.5% nickel, 5.5–7.5% manganese, and 0.05–0.25% nitrogen. This composition provides higher strength, improved work‑hardening capability, and a more cost‑efficient alternative to conventional 304 stainless steel.
The grade offers good ductility, weldability, and moderate corrosion resistance, making it suitable for structural components, decorative parts, and general mechanical applications. Its strong work‑hardening response allows significant strength increase through cold rolling, enabling the production of lightweight yet durable sheet structures.
1.4372 is available in cold‑rolled sheets, hot‑rolled plates, strips, and tubes. It is widely used in appliance panels, kitchen equipment, architectural decoration, transportation components, and light structural assemblies. As a cost‑effective substitute for 304, it provides a balanced combination of strength, formability, and corrosion resistance for projects requiring both performance and economic efficiency.
