Jérôme Duriez proposed the following answer:
Hi,

I think the simplest solution is to just use CohFrictMat for the steel as well. You may just use two different CohFrictMat materials in your simulation: one truly cohesive for the rock particles, and another one with e.g. zero cohesive properties that will apply to the steel.
Doing so, you would be able to use classical CohFrictMat functors in the interaction loop such as Ip2_CohFrictMat_CohFrictMat_CohFrictPhys

You might need to give a look to the corresponding code source [*] to be
sure how the cohesive properties of interactions are derived from the
cohesive Material parameters
