The maraging steel corrosion properties with hardening of different kinds after double aging
Engineering Education # 03, March 2014
DOI: 10.7463/0314.0699856
The paper examines a possibility to apply the ÈP 678 and ÈP 817 martensitic-aging steels to manufacture the force-measuring resilient member in electronic strain-gauge balance. It proposes to use double aging, namely main and low-temperature one as a hardening heat treatment after hardening. Microstructure, X-ray microanalysis, X-ray diffraction, potentiodynamic researches have been conducted, and structure and properties of hard-ended samples after main and double aging have been compared. It is established, that double aging causes extra hardening of steels, but it has a different influence on corrosion resistance of steel, namely the corrosive properties of AP817 steel containing copper are improved due to formation of uniformly distributed cathode ε-Cu corpuscles; the corrosive properties of AP678 steel are deteriorated because of increased heterogeneity of structure.
Corrosion resistance of welded joints of maraging steels for force-measuring elastic elements
Engineering Education # 10, October 2012
DOI: 10.7463/1012.0463200
 The authors study the effect of welding heat to corrosive properties of maraging steel, the influence of chemical composition of steel on liability to intergranular corrosion; they set a method of improving corrosion resistance of welds by use of surface treatment.
