I made a simple Resourcepack that changes the name of the items and blocks from the mod "Pigsteel" to Inferrum. I simply think it makes sense given iron can be obtained thanks to the mod resources, and not steel, it may also fit some Modpacks better, and, I think it is a cool, fitting name.
Infernus+Ferrum (Iron) = Inferrum
I've also included a es_es translation, that localices it to "Infierro".
I don't mean any disrespect towards the Pigsteel DEVS, whom I thank for creating the mod in the first place, you can find the mod for Forge and Fabric:
Pigsteel [Forge] Pigsteel [FABRIC]
I tested this with the Fabric version, if anything goes wrong in Forge or you want to talk about anything you can find me as @Jasdan in Discord.
You are free to include this Resourcepack, partially or on it's enterity on Modpacks, or as part of a mod, you may also rehost it if you require to do so.
