Abstract (en)

[origin: EP2351866A1] 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 stabiliser which are present at respective levels to achieve a balance between their effects whereby the white iron is substantially crack-free. The white iron may be as-cast or comprise well deposited hardfacing.
