The metallurgy of the unit is predominately SS347 and SS316. The areas I'm mainly concerned about are the wash water injection point which is at elevated temperatures (~250F) and dead ends. Wash water is injected in large excess so there is no chance of drying out. Heat tracing maintains temperature above water dew point in the hotter parts …

Comparison between 347 stainless steel and 321 stainless steel. Alloy 321 (UNS S32100) is a very stable stainless steel. When the temperature reaches 800-1500 ° F (427-816 ° C) and chromium carbide precipitates, it still …
The chemical and mechanical properties comparison of SS321 to SS347 are also shown in the below table. SS321 vs. SS347. Both SS321 and 347 are austenitic stainless steel grades having similar mechanical properties and major alloying elements. The only difference is the microalloying elements. While Titanium is added into 321 …
Alloy 347H (UNS S3409) stainless steel plate is the higher carbon (0.04 – 0.10) version of the alloy. It was developed for enhanced creep resistance and for higher strength at temperatures above 1000°F (537°C). In most instances, the carbon content of the plate enables dual certification. Alloy 347 stainless steel plate cannot be hardened ...
The most common of these stabilized grades are types 321 and 347. Type 321 contains a minimum of 5 × (C% + N%) titanium, and type 347 a minimum of 8 × C% niobium. Nitrogen must be considered when titanium is used as a stabilizer, not because the precipitation of chromium nitride is a problem in austenitic steels, but because titanium …
The LWDC SS347 nozzle was fabricated from a forging and final machined including water jet milled channels. This nozzle was then closed out using LWDC. The Inconel 625 and Haynes 230 liners used the wire arc additive manufacturing deposition process for the starting liner material. The Inconel 625 channels were cut using WJM and …
Alloy 347 (UNS S34700) is a columbium stabilized austenitic stainless steel with good general corrosion resistance and somewhat better resistance in strong oxidizing
Type 347 is a stabilized austenitic stainless steel similar to type 304 with an addition of Columbium and Tantalum. The columbium serves to produce a stabilized type of stainless steel which is immune to chromium carbide precipitation. This type of grades are thus recommended for parts fabricated by welding which cannot be subsequently annealed ...
ABSTRACT. Stabilized austenitic stainless steel (SS) grade 347 is used extensively in high-temperature processes in the petroleum refining industry, while duplex SS (DSS) grade 2205 is a relatively newer material in the industry. Though these grades of SSs perform well in refinery process streams, there are incidents of failure of process …
