    Stainless price escalation

    I need a good source to show the trends of stainless steel prices over the last 5 years. Does anyone have a handle on this and can you direct me to some hard numbers. THanks, GG

    Price increases

    Does anyone have a good source for the recent price trends in corrosions materials (hastally and 2205). I'm looking at the last 5 years and trying to establish a firm basis for some budget increases at my plant. Thanks, Gene G.

    Price increases

    Can anyone tell me a good source for the price trends of boiler tubes over the last 5 years. I know there has been increases but I am trying to nail down the amount to help me justify some budget adjustments. Help would be appreciated.

    2205 flux core welding

    I have some tank work dealing with 2205 alloy. One of my bidders has proposed a flux core wire welding process. I am not familiar with flux core in a duplex stainless application. Is this inferior wire feed using a shielding gas? What are the trade-offs if any? Any input would be appreciated.

    AR Plate and temperature performance

    Hello all. Need some advice We have been using 400 and 500 AR type plate in our ductwork for wear resistance due to massive amounts of flyash. At one point in this ductwork the temperature runs about 700 F and at another part it is about 350 F. What I am wondering is at this temperature...

    2205 machine welding

    All, Need some advice. I just visited a shop where we are having some 2205 ductwork fabricated for FGD outlet duct use. I know that termpature and HAZ is important and bead sequence should be watched. When I got to the shop they used a machine to weld about 70% of the welds. I inquired...

    Fly Ash Erosion

    I have a boiler burning lignite with 29% ash. As you can imagine the flyash erosion is mind boggling. Ducts, Boiler tubes, economizer, precip, etc. all take a beating. What type of materials have proven to be cost effective solutions in this severe application?

    2205 wire weld material

    I have some left over spools of C 276 from a previous project. This year we are fabricating new FGD ductwork of 2205. I would like to use this C 276 wire instead of 2209. Any thoughts?

    Up Alloying weld material?

    For 2205 of other duplex stainless steels the weld and HAZ is much weaker (especially if too much heat input) than the rest of the material. This is to be used in outlet FGD ductwork. I'm wondering if using C-276 wire for the welds would eliminate that weakness of would the HAZ extend past the...

    Fan blades brazing

    I have some stainless ID fan blades at a power plant. We are considering having Conforma-Clad or a similar company braze tungston carbide onto the leading edge. To perform this process they bake the part at around 2000 degrees F. This is a twisted and tapered blade and the profile is...
