Please check the sample prep for G48 corrosion test. If the diluted zone on the bottom of the weld is not removed completely you are to find pitting on the bottom side. Since it is manual overlay you may have to make the samples thinner to reflect undiluted chemistry on top and bottom. Also...

For corrosion resistant 304L 0r 316L cladding we use 0.0125" as standard thickness.

Nitriding is beneficial on the threads provided the case depth is narrowed down. We nitride to a depth of .002" to .003" on threads for better results.

Thank you Ed & SJ for your inputs. Ed - Is it possible to share any supplier that stocks cold worked material.

Peers, We are Choke valve manufacturer and use Nitronic 50 for Choke Stems. It is governed by Table A.3 in NACE0175-3. However, Table A.3 allows/mentions only 1 supply condition as solution annealed followed by cold working to a max 35HRC. Steel mills doesn't supply solution annealed and cold...

Press Equip - I have used STT in the past for weld overlays including Inconel 625. We were successful in developing procedures for under 10% dilution. It is still manual(semi automatic)application. Fronius CMT was not around at that time. In recent years CMT is becoming popular big time. Trials...

Press Equip. Please visit TIP TIG USA http://www.tiptigusa.com/ There are distributors around N.A and Canada.I do have local distributor and i am in Canada.

Isothermal annealing would be more suitable for 20MnCr5.

I will pass the supplier info soon. less than 5% in 2 layers.

We use pulsed Hot wire TIG process in both flat and horizontal positions for Inconel 625 overlay and can comfortably achieve less than 5% dilution, meet NACE 0175 and API 6A requirements. You also have to be careful about the inconel 625 filler metal. There are only a handful of good Inconel 625...
