US to Canadian steel types - are we getting what we specified?

[KM]

We wanted weldable notch-tough structural steel to CAN/CSA G40-21 grade 350WT.

Supplier proposes American A992 steel with average of 3 Charpy test results being 37 foot-pounds at -20 degrees F.

Can't find in "CISC Handbook of Steel Construction" exactly what are the Charpy requirements for WT steel. Does anyone have these?

Am trying to figure out if the proposed material is indeed equivalent to WT steel.

You should be fine for impact. According to SSAB, minimum impact for C40 Grade 350WT is 27 J (20 ft-lb) for the temperature range between -45^o C to 0^o C.
