Welding S355 Steel to D1.1 Code

By Jeff Carney Date 07-22-2013 19:03

Welding S355J2C+N steel to API 2H Grade 50.

My question is, for the purposes of prequalified base metal filler metal combinations for matching strength (table 3.1, D1.1), what is the ASTM equivalent and which D1.1 Group number does the S355 material fall under? API 2H G50 is a group II (p. 66 D1.1-2010).

The closest information I could find indicates that the S355 may be an ASTM A572 material, but I have found nothing definitive.

Your assistance would be appreciated.

S355J2C is a steel manufactured to European standards. It is not a listed prequalified steel in AWS D1.1, so you would have to qualify the welding procedure if you wish to meet AWS D1.1 requirements.
