00Cr18Ni10N Stainless Steel Composition & Nitrogen‑Enhanced Austenitic Properties

00Cr18Ni10N is a nitrogen‑enhanced, low‑carbon austenitic stainless steel specified in GB/T 4237 and GB/T 4238. The addition of nitrogen increases yield strength, improves pitting resistance, and enhances austenite stability while maintaining excellent corrosion resistance and weldability.

The grade is suitable for pressure vessels, storage tanks, seawater systems, chemical equipment, and structural components requiring higher mechanical performance. Compared with standard 304L‑type materials, it provides improved load‑bearing capacity and localized corrosion resistance.

00Cr18Ni10N is available as plates, sheets, strips, tubes, and bars. It is widely used in energy equipment, marine engineering, pharmaceutical installations, and high‑purity fluid handling systems.
