MagnaMax™ PM Stainless Knife Steel
DATA SHEET
MagnaMax is a high-performance PM stainless steel designed for enhanced wear resistance and edge retention while maintaining strong toughness and corrosion resistance.
Recommended Heat Treatment
| Step | With Cryo (Preferred) | Without Cryo |
|---|---|---|
| Austenitize | 2100–2250°F (2150°F recommended) | 2050–2100°F (2100°F recommended) |
| Soak Time | 5–20 minutes depending on temp | 5–20 minutes depending on temp |
| Quench | Plate Quench | Plate Quench |
| Cold Treatment | Immediate Liquid Nitrogen (~1 hr) | Immediate Freezer (~1 hr) |
| Temper | 300–450°F, 2x2 hrs (350°F recommended) | 300–450°F, 2x2 hrs (350°F recommended) |
Cryogenic treatment significantly increases achievable hardness and allows higher austenitizing temperatures without loss of performance.
Tempering curves at 300-450 F: The recommended practice of Austenitize 2150F, followed by Liquid Nitrogen + 2 x 350F tempers resulted in 63-64 HRC.
Toughness tests at various Austenitize and tempering temperatures.
Expected Properties
Hardness: ~63–66 HRC
Toughness: Comparable to CPM-154, S35VN, Vanax
Wear Resistance: Higher than CPM MagnaCut
Corrosion Resistance: Comparable to CPM MagnaCut
