CPM S45VN is the updated version of CPM-S35VN. The chemistry has been rebalanced to improve corrison resistance, wear resistance and edge retention. It also has increased Carbon and a some Nitrogen added to allow for higher hardness than CPM S35VN. Toughness is better than CPM S30V, but slightly less than CPM-S35VN.

Heat Treatment for CPM S45VN

Wrap blade in stainless steel heat treat foil

Bring to 1550/1600F and equalize (let it soak for 10 minutes)

Bring it up to Austenitizing temp 1900 - 2000F 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 300F to 500F twice at 2 hours each time. Cool to room temperature in between tempers.

Austenitizing at 2000F followed by a Cryo treatment and tempering at 400F should result in a hardness of 61-62 HRC
