Composition of Elmax Steel
Elmax is a particle metallurgy stainless steel made by Uddeholm. It is a well balanced knife steel that offers very good corrosion resistance, edge holding and good toughness. It is a good steel to choose for almost any type of knife, including high quality hunting knives, kitchen knives, or folding knives.
Heat Treatment for Elmax
Wrap blade in stainless steel heat treat foil
Bring to 1500°F and equalize (let it soak for 10 minutes)
Bring it up to Austenitizing temp 1980° - 2010°F and hold for 30 minutes
Quench in air or plate quench.
A Cryo treatment in liquid nitrogen (or dry ice) before tempering will reduce retained austenite and increase hardness
Temper between 350°F - 400°F twice for 2 hours each time. Cool to room temperature in between tempers.
Austenitizing at 2010 F followed by a Cryo treatment and tempering at 400F should result in a hardness of 60-61 HRC
