ABSTRACT

A wear resistant, high chromium white iron, in an unheat-treated condition has a microstructure substantially comprising austenite and M7C3 carbides. The white iron contains at least one martensite promoter and at least one austenite stabilizer which are present at respective levels to achieve a balance between their effects whereby the white iron has a microstructure characterized by at least one of: i) being substantially free of martensite at interfaces between the austenite and M7C3 carbides; andii) having a relatively low level of interconnectivity between carbide particles; such that the white iron is substantially crack-free. The white iron may be as-cast or comprise weld deposited hardfacing. More... »
