ASTM G98 Unprecedented galling test:
= Expanite surface hardening prevents galling!
Galling, or adhesive wear, is a pervasive problem for stainless steels, of which the soft austenitic alloys are notoriously prone. In an on-going effort to increase its database of engineering data, Expanite®
recently conducted the ASTM G98 Standard Test Method for Galling Resistance of Materials on AISI 316L, with and without Expanite® surface treatment. The results were remarkable, and challenge the conventional wisdom that a 'hardness differential' in a material couple is required to resist galling.
