    A stainless steel tool chuck was cracking during product assembly, affecting about 30% of all chuck. A failure analysis of the cracked chucks and analysis of the chuck design and manufacturing process was performed to determine the root cause of the cracking. This article discusses the findings and how the problem could have been prevented.[price]Electric cars Page 4 Trap Shooters Forum[steel]Nov 08, 2019 · Hydrogen Embrittlement of Steel Industrial Metallurgists Hydrogen embrittlement is a metal's loss of ductility and reduction of load bearing capability due to the absorption of hydrogen atoms or molecules by the metal. The result of hydrogen embrittlement is that components crack and fracture at stresses less than the yield strength of the metal.[price](PDF) Towards a unified and practical industrial model for [steel]Towards a unified and practical industrial model for prediction of hydrogen embrittlement and damage in steels Article (PDF Available) · July 2016 with 1,173 Reads How we measure 'reads'

    High Temperature Hydrogen Attack an overview

    Prevention of high temperature hydrogen attack. To prevent the formation of methane inside steels, metallurgical choices involve the replacement of iron carbides in steels by carbides more stable with respect to hydrogen, such as chromium, molybdenum, titanium, vanadium or niobium carbides (alloyed steel addition elements).[price]Corrosionpedia Corrosionpedia Contributors Michael Pfeifer[steel]Michael Pfeifer He provides metallurgy training and metallurgical engineering consulting to companies involved with product development and manufacturing.
