ASTM Equivalent for British Standard 1

[phillyfunk]

I'm looking for a north-american equivalent for

BS 4360 Gr. 43C and BS EN 10025 S355 J2G3

If anyone is familiar with these two materials please help, my project depends on it.

Thanks

BS 4360 43C is a structural grade like ASTM A 36 but with guranteed charpy properties:
C .19 max, Si .5 max, Mn 1.5 max
UTS 62,400 psi
Yield Strength depends on thickness but up to 1.5-inch would be 35,000 psi

Charpy impact tested at 0 degrees C (-32 Degrees F)minimum average impact toughness 27 J (20 ft lb)

The equivalent to EN 10025 is ASTM A 1011/1011M. The equivalent grade to S355 J2G3 is SS Grade 50 [340]. The BS standard must be obsolete by a number of years, as I do not see any mention of it in my references.
