Hi IFI
I work as a machinist and at work I often talk to my colleague about forging, he gave me some material to try forging at home. I went home to forge it and for the first hour it was alright to hammer the material, but after 4 hours of hammering I started getting nowhere. I asked him back at work what kind kind of material he gave me and he said it was special tool steel. I complained for a while as I barely could hammer it. He then said that since I'm using a coal forge, I'm passively increasing the carbon content in the steel. I was aware of this, but I didn't think it would be by such a huge amount.
my question is does anyone have an estimate on how much it matters? And how much carbon is added to the steel?
Best regards
