The role of Nitrogen in improving corrosion resistance of stainless steels

During the early development of stainless steels, nitrogen would have been an unintentional alloying element. However, the advent of modern steelmaking processes such as AOD (argon oxygen decarburisation) and VOD (vacuum oxygen decarburisation) allowed its level to be carefully controlled.

How does Nitronic® 50 compare with other alloys?

Nitronic 50 is an austenitic stainless steel, produced with an increased nitrogen content which improves its strength and corrosion resistance. This alloy is also widely referred to as XM19, which is the designation of the generic alloy caption in ASTM A276 and ASTM A479, as well as UNS S20910 or DIN 1.3964. Nitrogen, along with chromium and molybdenum all increase the Pitting Resistance Equivalent Number (PREN) to >34, which is a similar value as S32205 duplex stainless steel and way above low-alloyed grades.

What are Duplex grades 1.4462, 1.4410, 1.4501 AND 1.4507?

DIN EN 1.4462, 1.4410, 1.4501 and 1.4507 are duplex and super duplex stainless steel designations used across multiple DIN, EN and ISO standards.

DIN stands for Deutsches Institut für Normung e.V., and it is the German national organisation for the creation and maintenance of around thirty thousand DIN Standards, covering nearly every field of technology. Most of the relevant DIN standards are incorporated in to Euronorm (EN) standards for adoption beyond just Germany.
