8670 Bar Stock Steel .250" Thickness - See Length Note
8670 is an extremely tough Carbon steel commonly used for large bandsaw blades found in the lumber industry. The nickel content along with the carbon content creates a very durable steel that also can hold a strong edge. It will be a great steel for big choppers and hard use blades

Heat Treatment for 8670 Carbon Steel
Place blade in forge or Heat treat oven pre-heated to Austenitizing temp 1500°F (soak for 5 - 10 minutes if using a heat treat oven)
Quench in fast oil like Park's 50
Temper between 350° to 400°F twice for 2 hours each time. Cool to room temperature in between tempers.
This Should give a hardness of 60-62 HRC
