So, what is the difference, and why use 2 different types of steel in your forged iron offerings?
From a metal standpoint, the characteristics of the materials, specifically the hardness, are very similar. 8620 is a form of carbon that is used when casting carbon steel because it flows better into the cast tool. In form forging, the first step is to cast the head, then after casting, it goes through one forged press process. That is what form forging is. 1035, 1025 etc. are more usually used to describe the carbon steel used in a billet forging. Billet forging is simply where a billet of material is hammered into it’s final shape by going through a series of heating and forging steps.
