CREUSABRO 4800 to ST-37 Welding

(OP)
Hi,

Was wondering if its possible to weld CREUSABRO 4800 to ST-37?
The final weld seam isnt subjected to high loads.

Chemical compositions listed below are for max values and in % by mass.
CREUSABRO 4800: C - 0.20, Mn - 1.6, Ni - 0.20, Cr - 1.9, Mo - 0.4, S - 0.005, P - 0.018
ST-37: C - 0.17, Mn - 1.4, P - 0.045, S - 0.45

Thanks.

Yes, both materials can be welded to each other based on your stated chemical compositions.

Thanks!

RE: CREUSABRO 4800 to ST-37 Welding

Make sure you apply preheat for welding and consider post weld heat treatment based on material thickness at the weld joint region. You should also qualify a welding procedure specification.

@metengr, yeah i figured that for the welding of those two materials i should use the same pre-weld and post-weld heat treatment as recommended by the CREUSABRO manufacturer.

@RolMec, i found this document but there is no mention about welding this metal to another one.
