Study on the Microstructure and Performance of New Type Martensite Wear Resistant Steel
The new low alloy martensitic wear resistant steel 25Si2MnNi3 and steel 53Si2MnNi3 are developed, which hardness are about HB450 and HB600 respectively, the impact abrasive wear resistance of new low alloy steel relative to high manganese steel ZGMn13 is investigated on MLD-10 type impact abrasive wear tester under the different impact energy, and the wear mechanism is analyzed. As a result, the new low alloy martensitic steel which impact toughness is well always obtains better impact abrasive wear resistance than that of steel ZGMn13 under different impact energy, and the primary wear mechanism gradually changes from micro-ploughing and micro-cutting to micro-fatigue and micro-cracking with impact energy increasing.
