machinig and then heat treating sheet steel

[japesy]

Hi Guys,

I work with EN16t and EN24t in solid bar condition. I am looking for a sheet steel with similar specs

I want to make "spade heads" and fit the to a roller which will then be tractor puled and slice into the ground.

I will require laser cutting and then maybe heat treating to obtain a case hardened material scoring about 55 on the rockwell test.

Any advice as to the steel grade would be helpful
Material thickness 2.0mm 2.5mm and maybe 1.5 or near

many thanks

Richard

I'm not too familiar with your designations in the UK, but the threads in the materials forums seem to be a good place to try. A relevant thread below:
