Chromium is the worst thing we can have in the steel so I don't think it would work. We actually nuclear analyze our wcb bodies to make sure the trace elements are at a minimum
I have posted here a couple of times. I deal in the manufacturing/rebuilding of valves for HF acid service (aka..alky valves). I have recently been contacted by one of my customers to build an experimental valve with stellite over steel trim. We all know that for some reason stellite risists...
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.
We do our own overlay in house. In this particular situation the steel body valve is being severly attacked and a monel replacement is not readily availible. I'm looking for specific treatment to WCB steel to increase corrosion resistance (such as annealing).
Factory support is not an option. We are an independant buisness for the most part. We are an authorized repair center for Durco acid valves I was just looking for some info or suggestions I haven't heard before. We have done this a long time and have a good handle on it.
I just recently had...
Hi,
I stumbled across this board surfing and it looked like a very interesting place.
I have a question about corrosion resistance of steel by HF acid. I work in the valve industry and repair many valves for alky units in refineries. I was wondering if cryo treatment of WCB steel would...
I am a mechanical engineer in the industrial valve industry and deal a lot with valves in HF acid service. Is there any kind of treatment that can be done to steel to improve corrosion resistance? I know that annealing B7 studs improves corrosion resistance but have not heard of anything being...
I am looking for some good books that deal with heat treating (carbon and stainless steel). I am a mechanical engineer and also a beginning gunsmith and I am looking for books that will help me out in this area. I can interperet metallurgy books but am looking for something a little more...
