We use 316L stainless chain to drop Zinc Ingots into a galvanizing bath. The bath temperature is 880F. Bath chemistry is 99.5%Zn 0.30%Al 0.005%Fe 0.015%Sb. The chain is submerged beneathe the bath while the ingots melt. The chain is only removed from the bath when more ingots are needed. On...
We are trying to repair rust pits at water jackets on a cast iron block with Solder and so far are unsuccessful. We've tried rod, silver solder with flux, tried arc welding with low melting point nickel rod none of which worked. Is there a way to solder cast iron at low temperature, keep cast...

Our boiler is burning very inefficiently. I have modelled our system with SSAT software for Excel and made my own calculations and I get the same results.
We have a 20,000lb/hr fire tube boiler. We burn Natural Gas. On average our the facility only draws 6,000lb/hr steam at 140psi. I have...
We have two plate heat exchangers. They have approximately 50 plates each. They are continuing to get an algae buildup inside which must be cleaned by dissasembling the heat exchangers. We have Bromicide in the tanks, but the algae builds up anyway. The algae is a orange brown color.

I want to clean the zinc off a sink roll in a galv line pot using an HCl bath. The roll would be dipped in a 15% HCl concentration to remove the zinc. I am assuming we will still need to machine the surface once we remove the roll? I want to know if the HCl could be corosive enough to cause...
