Dear All,
This has reference to trailing mail, My client is asking hardness 88 RB max.on SS410 S weld overlay. Whether is it pratically possible? Your quick opinion on this issue is requested. Thanks in advance. Vinit

| Requesting Expert views on following case.
Design Code.: ASME SEC VIII DIV.1 MOC : SA387 GR.11 CL.1 + SA 240 GR.410S CLAD
THK. : 60.0 mm + 4.0mm
Clad restoration by E309 LMO(Barrier Layer) + E410(Subsequent Layers) welding electrodes. Undiluted chemistry at 2/3 depth from the top shall meet with restriction Carbon Content 0.06% Max., Nickel Content 0.7% Max.Chromium Content 11 to 13.5%. Can we achieve hardness 88RB (176 BHN)on weld overlay of SS 410S after taking all care of Pre heat(150°C min.),Post heat (300 - 350°C@ 2 Hrs.) and PWHT (700°C@3 Hrs.). OR How much we can get? As per my Qualified Welding Procedure Hardness could achieve Between 240 to 260 BHN.
Please share your experience.
