RE: 43] Welding Procedure for DIN wb 36(1.6368) to 16mo3(1.5415).

[Bathula Raghuram (Mumbai - PIPING)]

WB36, which is a German low alloy steel (LAS). It differs from typical LAS's primarily by the presence of Cu, which causes precipitation hardening, thereby increasing the strength by about 15-20KSI (103-138MPa) compared to a typical ASME/ASTM LAS, without decreasing the ductility.

 

15NiCuMoNb 5 (WB36,1.6368) is in Germany applied as PV-steel (up to 340°C) in some NPP and as pipe material (below 300°C) in many fossil power plants

Also you may refer code case 2353 in ASME BPV for this material

Main composition:

0.15%C, 1.15%Ni, 0.65%Cu, 0.35%Mo, 0.02%Nb

 

16Mo3 (DIN17175) is another typical LAS with 0.5 Mo, which is equivalent to ASTM A 204 Gr.A/B (UNS#K11820, K12020)

 

Recommended consumables For; GTAW: Bohler DMO-IG (ER80 S-G); SMAW: Bohler Fox DMO Kb (E7018-A1 H4R)

 

 

Please elaborate your question on where you use this for application as well service, Design code etc. to guide you further as well as for the academic interest of members here.

Dear Mr. Surya prakash

Please ensure to change the subject line before posting a mail

 

Please state details of the item (is structural, pressure vellsel), design code, whether it is ASME, AWS or DIN?

And what process u wants to adopt?

dear all,

 

i require the wps for  (1)din wb 36(1.6368)   to   din 16mo3 (1.5415).

 

 

regards,

 

surya prakash.

dear raghuram ,

thank you for the reply,

 

this is used in power plant service.

[Raghuram]

Can please tell why do u select this material, is it client
requirement, are you fabricating this for a German plant? and for
which service (BFW, steam etc.) and operating conditions, just for the
academic interest of members here..

Thanx

[gajjalla surya prakash]

this is for the semens plant comming up in saudi,and material requirement is clients requirements,and you are  correct it is for steam lines.
