The key characteristic of austenitic Hadfield steel is high resistance to the abrasion wear. Different applications mean various operating conditions and different types of abrasive wear.This paper compares the two abrasive resistance testing methods on rolled sheets of manganese (Hadfield) steel. As the base for samples selection were chosen the sheets of standard production. For the comparison of abrasive resistance was used test in shot blasting machine and impact test on laboratory equipment developed at University of West Bohemia. The aim was to verify if new method (Impact test) can be used for abrasion wear resistance testing. The Shot Blast Test compares the weight loss of the tested material, while the Impact Test evaluates the magnitude of the repeat imprint of the test indenter.The Sample A reached the best wear resistance results in the both testing methods. The Impact Test method is a simpler and cheaper alternative to the blast test in terms of determining the expected resistance to abrasive wear.
