Effect of Oxygen and Nitrogen Oxide Gas Concentration on Corrosion of 310N Stainless Steel in Solar Salt at 600°C

open access: yesMaterials and Corrosion, EarlyView.
Schematic depicting corrosion layer formation and changes in stainless steel exposed to Solar Salt at 600°C for 1000 h under different atmospheres: (a) N2 accelerates salt decomposition, producing nitrite and oxide ions, causing severe corrosion. (b) Adding O2 reduces nitrite ions formation, resulting in less corrosion than N2 alone.

Corrosion Behavior of Commercial FeCrAl and TiAl Alloys in Molten Pb With 2E‐7 wt% Oxygen at 600°C and 700°C

open access: yesMaterials and Corrosion, EarlyView.
Excellent corrosion resistance of commercial Al‐containing materials is shown for exposures to liquid lead (Pb) at 600°C. However, oxide scale failure occurs at 700°C. The formed oxide scales and their failure mechanisms are explored. ABSTRACT Liquid lead (Pb) is an attractive heat transfer fluid for advanced thermal energy storage (TES) systems.

Influence of Higher Tramp Element Level on the Weldability of Automotive Steels

open access: yessteel research international, EarlyView.
The use of green recycled steels is constantly expanding in the automotive industry. The increase in tramp elements resulting from the recycling of steel is problematic. Tramp elements can lead to a negative influence on the weldability. To understand the influence, the welding properties of three green steels are characterized. The potential limits of
