The steel generally will be half or nearly fully hard depending on the type. It may often have mill scale residue. This steel can be easily forged. It can also be ground via stock removal. Drilling a hole in the tang maybe hard to do with out a carbide bit. HRA is the same but the steel was later annealed to relieve stress and make it as soft as possible for easier machining. Several companies produce "powder" smelted steels. This is a premium smelting process that improves the mixing of alloy content and generally produces a finer grain structure as a result. The powder steels are nearly always annealed and can be assumed to annealed unless noted otherwise. Heat Treatment for CPM MagnaCut Wrap blade in stainless steel heat treat foil Bring it up to Austenitizing temp 2050F and hold for 15 - 30 minutes Quench in air or plate quench. A Cryo treatment in liquid nitrogen (or dry ice) before tempering will increase hardness Temper between 350F twice at 2 hours each time. Cool to room temperature in between tempers.
