Elmax vs CPM S35VN
Elmax and CPM S35VN both occupy the same well-rounded, no-major-weakness tier of premium stainless steel, one from Bohler-Uddeholm and one from Crucible. They land close enough in toughness and edge retention that the deciding factor for most buyers comes down to corrosion resistance and availability.
Quick Verdict
These two are nearly tied. Toughness and edge retention are essentially equal, with Elmax holding a modest edge in corrosion resistance. Either is a safe, dependable choice for general-purpose knives, so the decision often comes down to which one a particular knife or blank happens to be available in.
Toughness
Tied. Both use a fine, round powder-metallurgy carbide structure that gives good resistance to chipping for steels in this performance class.
Edge Retention
Tied. Both offer solid, dependable wear resistance without leading the field in either direction.
Corrosion Resistance
Elmax holds a real advantage here, with roughly 18% chromium versus S35VN's 14%, making it the better choice for wet, humid, or marine environments.
Heat Treat
Both use broadly similar heat-treat windows (roughly 1900-2050 F austenitize with a cryogenic treatment and double temper), so neither is meaningfully harder to heat treat than the other at the shop level.
Grinding
Comparable. Both are moderately demanding powder-metallurgy steels that grind similarly and are easier to work than harder-edged steels like CPM S30V or CPM 20CV.
Best-Use Scenarios
Choose Elmax when corrosion resistance is a slightly higher priority, such as marine or humid-climate use.
Choose CPM S35VN for general EDC and hunting knives where either steel would perform well and availability or cost tips the decision.
