D) Oxidation is also important in high temperature services to prevent corrosion.

I'm gonna go with C. Stress cracking is the real enemy here. These anchors need to be tough as nails to handle the crazy stresses of those furnaces.

I agree, but I still think C) Stress cracking is the main issue we need to address.

I think it's A) Thermal fatigue because the anchors need to withstand repeated heating and cooling cycles.

Haha, I bet the right answer involves something with the word 'thermal' in it. These refractory anchors are like the superheroes of the high-temp world!

A and D seem like the correct answers to me. Refractory anchors need to be resistant to both thermal fatigue and oxidation in high-temperature services.

I'd go with B. Thermal cracking is the biggest challenge for refractory anchors. They need to be able to withstand the extreme temperature changes without fracturing.

Definitely D. Oxidation is the key factor that refractory anchors need to resist in high-temperature environments. Thermal fatigue, cracking, and stress cracking are secondary concerns.
