Sir,
How to do welding on Monel Casting. Whenever we do welding (major or minor / spot weld) we end up with a boundary mark in Dye penetrant testing around the fusion line (base/weld interface, in HAZ). No defects were revealed in weld metal. But only a boundary is appearing in fusion line...
Dear Sirs,
My reported Aluminium level was 0.032% and we checked from the chemical specimen which was poured from the ladle with spectrometer.
My customer requirement is 0.04% max. Its with in the required limit and we sent the casting.
But my customer was checked the Aluminium level on the...
Sometimes WCB Normalized (920 Deg C), Tempered (640 Deg C) & Quenched (920 Deg C), Tempered (640 Deg C) also getting ail in tensile test.
Required value: 485 - 655 MPa
Actual Value: 465 MPa
Please give your input for the same.
Inconel 825 (CU5MCuC), tensile & elongation is getting failed after solution annealing & stabilizing treatment. I have tried with only solution annealing treatment but that too getting failed but as per standard A494 we have to do solution annealing & stabilizing. The fracture surface doesnt...
During the chemical analysis of CF3M (final sample from melt) am getting Carbon - 0.025%. But after 2 or 3 weeks to ensure the same if I sparked the sample am getting +/- 0.002 - 0.004% variation. Is this variation is allowed for all type of steel samples and any standards for the same.
WCB with Normalized (940 Deg C) & Tempered (640 Deg C) are getting failure with lower yield and lower UTS. Please guide me to resolve it.
Similarly in the case of Inconel 825 (CU5MCuC) getting failure in elongation (Solution annealed 1900 Deg C & Stabilized @ 960 Deg C). How to solve it, the...
