Mechanical Properties and Corrosion Resistance of a Novel Ni-Cr-Mo Alloy,

ADVANCED ENGINEERING MATERIALS, Issue 1-2 2007
P. Huang
A new Ni-23Cr-18Mo (wt.%) alloy, designated as Nistelle Super C, was developed recently at Deloro Stellite Inc. for high corrosion resistance applications. Microstructure and phase transformation behaviour of the alloy were studied using SEM and DSC techniques, respectively. Mechanical properties such as stress - strain relation of the alloy and load , depth relation of individual phases of the alloy were determined under uniaxial tension and under nano indentation, respectively. Corrosion resistance of the alloy in oxidizing and reducing acids was evaluated in accordance with ASTM standard test designation G31-72. [source]

Corrosion characteristics of the wrought Ni-Cr-Mo alloys

MATERIALS AND CORROSION/WERKSTOFFE UND KORROSION, Issue 9 2005
P. Crook
Abstract This paper concerns the wrought, nickel-chromium-molybdenum (Ni-Cr-Mo) alloys, a family of materials with a long history of use in the chemical process industries. Their attributes include resistance to the halogen acids and resistance to pitting, crevice attack, and stress corrosion cracking in hot, halide salt solutions. The purpose of this paper is to characterize the performance of the Ni-Cr-Mo alloys in several key chemicals, using iso-corrosion diagrams. These indicate the expected corrosion rates over wide ranges of concentration and temperature. Furthermore, the differences between individual Ni-Cr-Mo alloys, and their behavior relative to the stainless steels are defined. The data indicate benefits of both a high chromium content and a copper addition, as used in Hastelloy® C-2000® alloy. [source]
