Abstract
The invention contemplates a method and means for making a dryer or the like roll having a ferrous metal surface provided with a surface coating of a hardfacing alloy, the ferrous metal surface having a thermal conductivity relative to silver taken as 1 cal/cm.sup.2 /cm/.degree.C./sec of at least about 0.06 the hardfacing alloy being a hardfacing heat, corrosion and wear resistant iron-group metal-base alloy mechanically and metallurgically bonded to said ferrous metal surface which is preferably made of cast iron, the hardfacing alloy coating having a thickness ranging from about 0.01 to 0.15 inch, the thermal conductivity of said coating being at least 0.05.
