WCB vs LCB?
(OP)
What is the heat treatment process between these two steels?
WCB(A216) and LCB(A352). They are the same as far as chemical make up but have a different heat treat procedure.

A-352 does not permit annealing because of its detrimental effect on toughness, while A-216 does because improvements in high temperature properties and resistance to graphitization can be achieved with an annealed, coarse grain structure. Normalizing, normalizing and tempering and specific quenching and tempering practices are used to provide microstuctures that are tough and provide ductility at low temperatures.
