parent mental is 25crmo4 to 25crmo4. Is 80S-B2 filler material is suitable or anything else one plz suggest

[Mehul Patel]

Dear Experts'

Plz suggest me filler metal for 25crmo4 & explain 80S-B2. 

[Vishwas Keskar]

Pl send details of mechanical and chemical properties of the base metal - 25 CrMo4

Pl detail out service conditions of components being fabricated 

Any specific application?

Thanks

1. General property which is found on 25Crmo4 material.

2. General application 

[Kannayeram Gnanapandithan]

25CrMo4 is equivalent 0.25%C, 1%Cr, 0.25% Mo which almost matches ur rod selection 80S-B2

Dear 

1. TIG/MIG Welding:ER80S-B2: A filler wire designed for welding Cr-Mo steels. It has good creep resistance and is suitable for high-temperature applications.ER90S-B3: This wire provides higher strength and creep resistance than ER80S-B2 and is appropriate for critical applications where higher tensile strength is needed.

90S-B3 is overmatched. B3 weld chemistry is 2.25Cr + 1Mo

Not necessary. 80S-B2 is more than enough.

Mr. Mehul Patel,

For welding 25CrMo4 steels, a 175 to 250-degree C preheat is suggested to avoid  

hot cracks, martensite forming, and residual stress concentration. Avoid rapid cooling  

to control increased hardness and brittleness.

E/ER 80S B2 contains around  0.08% C, 1.30% Cr, 0.55% Mo, and UTS & YS are 590 

& 490 MPa, and compatible with base metal.

Sridhar.
