alloy 625. Tensile Properties and Hardness Typical tensile properties of annealed and solution- treated material from room to elevated temperature are shown in Figures 3, 4, and 5. The approximate relationship between the hardness and tensile and yield strength of strip is shown in Figure 6.
PWHT of Inconel 625 cladding - Metal and Metallurgy
May 19, 2005I am reveiwing a contractor WPS for cladding F65 forging materials with 625 CRA in two layers up to 5 mm thick. Base material qualified is for 25.4 mm upwards. I note that the procedure is qualified with PWHT at 600 to 630 Celcius at one hour per inch - max 3.3 hours. I am uncomfortable with PWHT of Inconel.I should have added that the cladding process is mechanised TIG. CheersIt is standard practice to carry out a post weld heat treatment in order, among other things, to achieve the required hardness in the heat affected..It is a common practice to specify inconel where austenitic stainless steel would normally do because inconel does stand up to PWHT better than aus..See NACE MR 0175, page 14, clause 5.2.1 states "Overlays applied to carbon and low alloy steel or to martensitic stainless by thermal processes suc..Thanks one and all!Only thing to remember and ensure that the PWHTtemperature is lower than the tempering temperature of the Q&T for F65 Thanks and regards Sayee Pra..We have a joint of 1-1/2 Mo , line to vessel in hydrogen reformer service, that showed a defect in Rx after PWHT. After removing the transvers..First off, it would be of benefit if you could start a new thread instead of tagging it to an existing thread. My comments - as long as you do not..Second comment - after re-reading your post it would appear that you have no cladding, and are performing a local weld repair directly to the P-No4..mcisajp, Assuming that the repair is to the weld in the P-4 to P-4 joint, is your welding procedure qualified per ASME Section IX or an appropriate..Inconel 625 cladding on valves - Corrosion engineeringJul 16, 2009alternates to 625 inconel cladding - Corrosion engineering See more results[PDF]
