1.	Which of the following is/are the characteristics of the Knife-line attack?(a) KLA occurs immediately adjacent to the weld(b) KLA occurs in the stabilized steels only(c) KLA occurs in the non-stabilized steels only(d) KLA occurs in the stabilized steels and it occurs immediately adjacent to the weldThe question was asked by my college professor while I was bunking the class.Query is from Eight Forms in division Eight Forms of Corrosion of Corrosion Engineering
Answer» RIGHT choice is (d) KLA OCCURS in the stabilized steels and it occurs immediately ADJACENT to the weld Easiest explanation: KLA occurs in a NARROW band in the parent metal adjacent to weld and it occurs in the stabilized steels that are alloyed with niobium, titanium, and COLUMBIUM.
