Is it STRESS CORROSION.
We are having a Continuous Hardening & tempering Mesg belt furnace. Life of mesh belt , upon which the material is loaded is having very short life, only 3-4months. very expensiec affair. Isn't it.
Gear blanks, wt.600-850gms, are loaded upon the mesh belt, it move inside the furnace set at 880=B0C. at the end material falls into quench tank (sealed with oil stream) and mesh belt move down abd back into water bath.
mesh belt of steel SS 310.
We see corroded surface of the mesh belt. Slowly it get thin and breakdown.
What could be the reason. We checked down the water statsu it was having high chloride content not acidic...!!!
