1.	Which of the preventions is/are the preventions of hydrogen blistering?(a) Use of clean steel instead of rimmed steel(b) Applying metallic, inorganic and organic coatings(c) Use of substituting alloys such as nickel-based alloys(d) Use of clean steel instead of rimmed steel, applying metallic, inorganic and organic coatings and use of nickel-based alloysThe question was posed to me during a job interview.This is a very interesting question from Eight Forms in section Eight Forms of Corrosion of Corrosion Engineering
Answer» Right choice is (d) Use of CLEAN steel INSTEAD of rimmed steel, applying METALLIC, inorganic and organic COATINGS and use of nickel-based alloys Easiest explanation: Preventions of hydrogen blistering are: Use of clean steel instead of rimmed steel Applying metallic, inorganic and organic coatings Use of substituting alloys such as nickel-based alloys Removing poisons such as sulfides, arsenic compounds, cyanides, and phosphorus IONS.
