Outstanding abrasive wear results after Expanite hardening
Expanite treated parts achieve very high surface hardness of approx. 1000HV on Inconel 718 while the outcome on Monel K500 is approx. 500HV.
Abrasion wear is an extensive problem for stainless steels. In the on-going effort to increase the knowledgebase on abrasion, Expanite requested Bud Labs to measure the dry abrasion
characteristics of untreated and Expanite treated samples of austenitic AISI316L using the ASTM G 65 Procedure Expanite provides various solutions for hardening different products in Inconel and Monel achieving a surface hardness of approx. 1000HV on Inconel 718 while the outcome on Monel K500 is approx. 500HV.
The result
The ASTM G 65 Procedure is a standard test method for measuring abrasion using the dry sand/rubber wheel apparatus where weight loss is used as indicator for the wear resistance: the less the better.
The results are indisputable: The 316L with SuperExpanite is more abrasion resistant than the untreated sample approximately reducing abrasive wear by more than 60%.
