The alloy has very good corrosion resistance in mixed acid and high chloride environments.
UNS N08031 (Alloy 31, 1.4562) Stainless Steel. N08031 stainless steel is a superaustenitic (highly alloyed) stainless steel formulated for primary forming into wrought products. Cited properties are appropriate for the annealed condition. 1.4562 is the EN numeric designation for this material. N08031 is the UNS number.
the corrosion resistance of more expensive high Ni-Cr-Mo alloys in many environments. Cronifer 1925hMo (UNS N08926) was derived from the 904Lalloy, and Nicrofer 3127hMo (UNS N08031) was derived from alloy 28 metallurgy, by in-creasing the molybdenum content to 6.5% and fortifying the composition with 0.2% nitrogen.
Alloy 31, known as the advanced 6 Mo alloy is the higher-chromium-andnickel version, and imparts significantly improved corrosion resistance in a variety of media. Its localized corrosion resistance is superior to many alloys, including the N i-CrMo alloy 625, as shown per ASTM G-48 testing.
A corrosion-resistant alloy (CRA) is an alloy consisting of metals such as: When combined, such metals can promote corrosion resistance more than other components like carbon steel. This type of alloy offers reliable protection from corrosion, eradicating the need for expensive maintenance and repair.
corrosion and the resistance to crevice corrosion. UNS N08031, on the other hand, has a pitting corrosion temperature 85 C and a crevice corrosion temperature of 65 C, both values being in the range of nickel base alloys. The high resistance of UNS N08031 to crevice corrosion is especially advantageous
Alloy 31 is a nickel, chromium and molybdenum stainless steel with nitrogen and cupper additions. High resistance to pitting corrosion.
The weld was performed using the gas tungsten arc welding technique (GTAW) with a nickel-based alloy (UNS N06059) as filler metal. The galvanic corrosion generated by the electrical contact between the base metal, the HAZ, and the weld metal was estimated from the polarization diagrams according to the mixed potential theory.
