it is structural grade carbon steel. killed steel and supplied in as rolled condition for thickness upto 12mm, plates above 12mm will be normlaised/controled rolled, and it is weldable grade.
included in P number 1 2011 addenda of ASME IX.
27J CVN value is gaurenteed at -40 deg C, if specified by the purchaser
you can use normal CS WPS , which is being used for any P1 material

Dear group members,
To my knowledge, this material is a killed, fine grained, normalized and weldable steel, correct?
In my case, the material should be used for a railway bridge. Largest thickness: 50 mm
I assume from the composition and mechanical characteristics that it is rather similar to EN 10025-3, type 420N steel.
Can somebody tell more about how WPQR and WPS should be for the material?
Would it not be appropriate to Charpy test 50 mm test specimens at -20 deg C with acceptance at least 25 J to show welds and HAZ has at least same
toughness as the parent material?
All advise in regard to welding of the material is appreciated. Thanks
Kind regards
Kristian Lund Jepsen
