The term abrasion or wear resistance refers to the ability of materials and structures to withstand abrasion or wear.
Wear is a common challenge for stainless steel — even martensitic grades, despite vacuum hardening.
Expanite’s advanced nitrocarburizing process changes the game: with surface hardness levels reaching 1200–1500 HV, wear resistance is taken to a whole new level.
In ASTM G133 wear tests, SuperExpanite®-treated AISI 316 showed 168 times better performance compared to an untreated reference.
This impressive improvement comes without applying any coating — only nitrogen and carbon are diffused into the surface, making it up to 10 times harder.
