Question

Which of the following is/are the preventions of hydrogen embrittlement?

(a) Baking of steels at low temperatures (200°F–300°F)

(b) Alloying with nickel or molybdenum reduces susceptibility

(c) Practicing proper welding with low hydrogen welding rods

(d) Baking of steels at low temperatures, alloying with nickel or molybdenum reduces susceptibility and practicing proper welding with low hydrogen welding rods.

I had been asked this question in my homework.

I'd like to ask this question from Eight Forms topic in section Eight Forms of Corrosion of Corrosion Engineering

Answer 1

Correct choice is (d) Baking of steels at low temperatures, alloying with nickel or molybdenum reduces susceptibility and practicing proper welding with low hydrogen welding rods.

Explanation: Preventions of hydrogen embrittlement are:

Baking of steels at low temperatures (200°F–300°F)

Alloying with nickel and molybdenum reduces susceptibility

Practicing proper welding with low hydrogen welding rods.
