Re: [MW:17852] Welding and cladding SA-516 Gr. 60 + AISI 410S

Hi! I would like to share my experience with 410S overlay on CS i) If you try to overlay 410S/410  chemistry on Cs,  It does not pass in bend during bend test as per ASME sec IX (It cracks) if client is very stringent and he requires only 410S chemistry in such case you require to take waiver  for Bend test which is job specific    You can try with 410 consumable with low C% less than 0.04 (Which is very difficult to get( Some time even 309MoL/309L barrier  with subsequent layer by 410 chemistry being used)   ii) Some time you may use 410 Ni Mo to get satisfactory bend test results However weld chemistry will have Ni ,Mo but major element will of Cr which will be in the range of 410   iii) However my experience is a) ",client accepts the 309L/309MoL for 410 clad restoration and b)  for high temp service (Like coke drum)client accepts the NiCrFe3 or NiCrMo3 chemistry where there is no problem of crack during bend test   In such case PWHT temp governs as per  UCS56 of ASME Sec VIII Regards   Hegde P.B.     --- On Fri, 31/5/13, Ramin Kondori <raminkondori if clie@gmail.c would like tostry shareIom> wrote:s ring bend test as From: Ramin Kondori <raminkondori@gmail.com> Subject: Re: [MW:17849] Welding and cladding SA-516 Gr. 60 + AISI 410S To: materials-welding@googlegroups.com Date: Friday, 31 May, 2013, 2:54 PM 410S itself is not martensite but this is when you have a weld metal which is only consisted of 410S not mixture of carbon steel and 410S... Dilution will occur and chemical analysis of the weld will be totally different than 410S. When 410S is deposited on carbon steels, depending on the carbon content of the substrate, the resulted weld metal will be something new rather than 410S... Cr wil be around 6-8% and There will be martensite in resulted weld metal. This martensite, if exceeds certain levels will be problematic and should be avoided. Some references recommend a maximum of 30% martensite in the weld metal microstructure and some allow up to 50% martensite in the microstructure. This is only achievable by preheat... One safe method is to use a buffer layer such as 309L or 310 followed by a low heat input process like Pulsed-MIG for depositing the 410 (or 410S if it is available) layer to avoid a layer which is over-alloyed by Cr... Depending on the client, this becomes a difficult task as the client does not accept variations in Cr levels in top layer of overlay. So clear every thing with the client or inspector before proceeding.
