Dear Ravinder,
15 NiCuMoNb 5 is mainly using in power plants feed water line having high pressure and medium temperature (near about 400 degree).
The chemical composition is given below
| C | Mn | P | S | Si | Ni | Cr | Mo | Cu | Nb | N | |
| 0.10-0.17 | 0.80-1.20 | 0.025 max | 0.020 max | 0.25-0.50 | 1.00-1.30 | 0.30 max | 0.25-0.50 | 0.50-0.80 | 0.015-0.045 | 0.020 max |
The tensile strength is between 59 to 75 Kg / mm2
The composition & properties are nearly similar to P4 & P5 materials.
For GTAW welding filler wire ER-80SG is suitable
For SMAW welding electrode E-10018-G or E -9018-G is suitable(For both PQR will be get pass)

Dear all,
I am looking for this material
15 NiCuMoNb 5/1.6368 (WB36)
This is the pipe used for power plants of 600 MW. I could not able to match its spec. with ASME. I require one meter spool piece of diameter more than 12'' and thickness should be more than 40 mm for procedure qualification. I want to know following things.
1. Source of material.
2. What consumable to be used for GTAW/ SMAW/ SAW/FCAW.
3. The parameters.
4. PWHT heating cycle.
Regards
Ravinder Sharma
