URANUS B6 is a high-alloy austenitic stainless steel with low carbon content. It was originally developed and used for many years to resist corrosion in dilute sulfuric acid. It is one of the best stainless steels for very aggressive chemical environments, in particular sulfuric and phosphoric acids. This datasheet provides information on composition, physical properties, microstructure, elasticity, and tensile properties. It also includes information on corrosion resistance as well as forming, heat treating, and joining. Filing Code: SS-565. Producer or source: Creusot-Marrel.

URANUS B6N is a multipurpose austenitic stainless steel with excellent corrosion properties. This alloy, developed more than 40 years ago, has been improved by the higher addition of nitrogen to approx. 0.13% to increase its structure stability and corrosion resistance. See also URANUS B66, Alloy Digest SS-602, July 1995. This datasheet provides information on composition, physical properties, hardness, elasticity, tensile properties, and shear strength as well as fracture toughness. It also includes information on high temperature performance and corrosion resistance as well as machining and joining. Filing Code: SS-747. Producer or source: Creusot-Marrel. Originally published June 1999, corrected July 1999.

URANUS B26 is a superaustenitic alloy with 6 molybdenum and a pitting resistance equivalent number (PREN) equal or greater than 43. This datasheet provides information on composition, physical properties, elasticity, tensile properties, and shear strength. It also includes information on corrosion resistance as well as forming, heat treating, joining, and surface treatment. Filing Code: SS-610. Producer or source: Creusot-Marrel.

URANUS 52N+ is a chromium super duplex stainless steel with a pitting index equal or greater than 40. Improvements in the composition include optimization of the molybdenum and nitrogen. This is an improved version of URANUS 52N (See Alloy Digest SS-566, May 1994). This datasheet provides information on composition, physical properties, elasticity, tensile properties, and shear strength as well as fracture toughness. It also includes information on corrosion resistance as well as forming, heat treating, and joining. Filing Code: SS-592. Producer or source: Creusot-Marrel.

URANUS 76N contains high chromium, molybdenum, and nitrogen contents and has a pitting resistance equivalent number (PREN) ≥ 40. These factors explain why the duplex austenitic/ferritic stainless grade is very resistant to localized corrosion. The alloy has been used for offshore applications. This datasheet provides information on composition, physical properties, tensile properties, and shear strength as well as fracture toughness. It also includes information on corrosion resistance as well as forming, heat treating, and joining. Filing Code: SS-1028. Producer or source: Industeel USA, LLC.

The high chromium, molybdenum, and nitrogen contents of alloy Uranus B25 (also referred to as UR B25) and its pitting resistance equivalent number (PREN) of >=42 explain why the grade is very resistant to localized corrosion even in acidified oxidizing environments. The alloy has also been used for seawater applications. This datasheet provides information on composition, physical properties, microstructure, hardness, elasticity, tensile properties, and shear strength as well as fracture toughness. It also includes information on high temperature performance and corrosion resistance as well as heat treating and joining. Filing Code: SS-907. Producer or source: Industeel USA, LLC.
