ER410NiMo impact properties

Date 11-17-2003 20:47

Has anybody tested this type of material with CVNs at or near 0F (-18C). We are needing 50 ft-lb and our standard FCAW and SMAW electrodes don't usually make it even at room temperature. 40-45 ft-lb would be typical. I was looking at GMAW since the CVNs are usually better than FCAW or SMAW depending on the situation. Probably spray type transfer with 98%Ar, 2% O2.

Hi GRoberts,
I was looking in ESAB's cat. and ran across a FCAW wire (Dual Shield II 70T-12, AWS Class E71T-1/E71T-12MJ w/ 75Ar/25CO2 mix). They are claiming "As Welded #'s" of 101Ft-lbs @ 0F, 90Ft-lbs @ -40F, and 53Ft-lbs @ -60F. Never used this wire so I can't vouch for it.
Just thought the numbers exceeded what you were looking at.

I suppose I should have spelled it out clearer in the body of my question, but in order to clarify for other possible responders, as the title mentions, this inquiry is specifically about ER410NiMo. Sorry for the confusion.
