Wear-resistant iron base alloys

A homogenous iron base alloy possessing good hot hardness and excellent wear resistance, comprising:

• a) less than about 0.1 wt % carbon;
• b) about 6 to about 15 wt % chromium;
• c) about 1.5 to about 3 wt % silicon;
• d) about 29 to about 36 wt % of molybdenum;
• e) about 0 to about 15 wt % cobalt;
• f) about 0 to about 14 wt % nickel;
• g) at least about 40 wt % iron;
• and
• h) wherein the alloy contains at least one of nickel or cobalt, the total amount of nickel and cobalt being greater than 3 wt % but not more than 15 wt %.
