--Hardox, is an abrasion resistant steel, not very commonly used for structural fabrication. Here're two data sheets which tells almost the same story .
Welding considerations for this steels are quite tricky and requires very high level of preheat . To the best of my knowledge structural codes does not incorporate use of such abrasion resistant steel. If this material is acceptable for construction you should ask the WPS to supported by a qualified PQR form welding approval prior to production.
Thanks.

Dear Gents,
I got one WPS for hardox 450
Required Code: AWS D1.1
Plate Thk: 25mm
My concern is that as per given Data sheet there is not specified Tensile Strength ,on what basis we can accept Report of Tensile Test?
This is my first experience with unlisted material.
Thanks & Regards
