1Cr17Mn6Ni5N Stainless Steel Composition & High‑Strength Austenitic Properties

1Cr17Mn6Ni5N is a nitrogen‑alloyed austenitic stainless steel defined in GB/T 4237 / 4238. With about 17% chromium, 5% nickel, manganese, and nitrogen, it offers higher strength and improved pitting resistance compared with conventional low‑nickel grades.

It is suitable for pressure vessels, storage tanks, structural components, food‑processing equipment, chemical piping, and seawater systems. Weldability is good, and nitrogen helps maintain a stable austenitic structure after welding. 1Cr17Mn6Ni5N is supplied as plates, tubes, bars, and profiles. It is a cost‑efficient stainless steel for applications requiring both strength and corrosion resistance.
