To eliminate the problem of caustic embrittlement use sodium phosphate instead of sodium carbonate as softening reagents. Adding tannin or lignin to boiler water blocks the hair-line cracks and prevents infiltration of NaOH into these areas. Adding Na2SO4 to boiler water also blocks the hair-line cracks.

Embrittlement is a loss of ductility of a material, making it brittle. Various materials have different mechanisms of embrittlement.
What is grain boundary embrittlement?
Grain boundary embrittlement is a phenomenon where materials become brittle due to the segregation of impurities or the presence of defects at the boundaries between individual grains in a polycrystalline material. This can weaken the material and reduce its ability to deform plastically, making it more susceptible to fracture. Embrittlement can occur due to factors such as intergranular fracture, stress concentrators, and environmental factors.
