Failure Investigation of Alloy 625 Sockolets After Prolonged Service in an Ammonia Cracker Unit

Materials and Corrosion, EarlyView.
The failure of the sockolets was caused by intergranular cracking and fracture. The thick and highly brittle nitrided layer formed intergranular surface cracks, which propagated along grain boundaries into the base alloy substrate due to the presence of brittle Cr‐rich carbides. ABSTRACT Several sockolets of Alloy 625 operating at 540°C in contact with

Experimental and Comparative Study of the Corrosion Behavior of Lean Duplex Stainless Steel in Seawater

Materials and Corrosion, EarlyView.
The localized corrosion behavior of lean duplex stainless steel EN 1.4062 is systematically compared with austenitic and higher‐alloyed duplex grades in natural seawater. A clear resistance ranking is established, highlighting EN 1.4062 as a cost‐effective alternative for limited marine exposure.

Chromium Salt: A Review of Salt Formation, Hygroscopic Properties, and Impact on 316 L Corrosion in Hydrochloric Acid

Materials and Corrosion, EarlyView.
This article examines the impact of externally introduced chromium compounds on the localized corrosion of 316 L stainless steel in acidic chloride environments such as hydrochloric acid. While the corrosion resistance of 316 L relies on the formation of a chromium‐rich passive oxide layer, industrial conditions may expose the steel to various chromium

Cold Gas Sprayed Titanium Coating for Corrosion Protection of Bipolar Plates in Proton Exchange Membrane Water Electrolysis

Materials and Corrosion, EarlyView.
Climate‐neutral green hydrogen is produced via water electrolysis using renewable energy. This study explores using cold gas spraying to apply titanium coatings on steel bipolar plates for proton exchange membrane water electrolyzers. The coating shows effective corrosion protection, presenting a promising solution for future designs.

Improved Corrosion Resistance of a Micro‐Alloyed Carbon Steel Assessed by Multi‐Element Electrical Resistance Probes and Coupons in Natural Seawater and Soil

Materials and Corrosion, EarlyView.
Multi‐element electrical resistance probes fabricated from industrial carbon steels enable real‐time corrosion monitoring in natural seawater and soil. A micro‐alloyed grade (AMLoCor) demonstrates up to 2.4 times improved uniform corrosion resistance over conventional S355 GP steel.
