Re: [MW:30330] Re: Filler material Selection

While welding CS with 316, ( chemistry 19Cr+12Ni), there is loss in Cr and Ni more 316 when compare with 309( 24Cr+13). For maintaining austenetic structure in ASS( as per code B31.1, which is attached) minimum requirement of Ni is 8, which may not be achievable with 316. So, it is better to use 309 instead of 316

Dear Experts,

Require guidance on filler material selection as per ASME BPVC.

For example:I received this query from a client

Base metal is ASTM A106 Gr.B and they want to weld using E316L electrodes.

Is it possible to use E316L electrodes to weld directly?

Regards,

Navanith
