Industeel URANUS® B28 High Nickel Super-Austenitic Stainless Steel

 

Subcategory: Stainless Steel; Metal; Austenitic

Key Words: EURONORM X1 Ni Cr Mo Cu 31.27.4, AFNOR Z2 NCDU 31.27.03, DIN W. Nr 1.4563, UNS N08028

Material Notes:
Description: URANUS® B28 (UR B28) is a super-austenitic stainless steel with very high nickel (31%) and chromium (27%) contents. The molybdenum content is about 3.5%. The alloy is designed for specific purposes, including sulphuric or phosphoric acid applications. It behaves particularly well in sulphuric and phosphoric acid environments, even when contaminated by chlorides and fluorides species. The high nickel content improves its stress corrosion cracking resistance. The combined chromium and molybdenum additions contribute to increase drastically the localized corrosion resistance. The alloy behaves much better than alloy 825 and could be considered in some applications (sour gas) to replace the more expensive 625 grade. The alloy is extensively used in chemical and offshore applications including very sour gas fields.

Iron content calculated as remainder.
