A. Martensitic steels are less susceptible to pitting corrosion than austenitic steels
B. Pitting corrosion is usually very localised
C. Hydrogen embrittlement is facilitated by tensile stress
D. Stress corrosion cracking is facilitated by tensile stress

A. Carbon and other alloying elements get oxidised from the weld pool
B. Excessive ferrite forms in the heat affected zone leading to poor toughness of the weld
C. Martensite forms in the heat affected zone leading to poor toughness/ductility of the weld
D. Segregation of carbon and other element occurs in the weld pool leading to poor properties of
the weld
