8670 is an improved version of 5160 with better comparable toughness and edge holding thanks to the added Nickel and Carbon. This is a great starter steel with an easy heat treatment (Possibly the easiest and most forgiving heat treatment cycle of all the steels we sell!). It is not only a great steel for stock removal but also forges very easily to!
