Previously we reported that the martempering process is excellent as a heat treating method of card clothing wire. Here, we studied the influence of steel making process on the properties of martempered and finished card clothing wire and similar high carbon-steel wire. The results were as follows : <BR>1. The card clothing wire of acidic open hearth steel with 0.8 % manganese had slightly higher tensile strength than the commen hard steel wire of acidic and basic open hearth steel with a similar composition but with 0.5 % manganese, when they were martempered in the same condition.<BR>2. The wire made of the acidic open hearth steel had slightly higher tensile strength than the wiwire made of the basic open hearth steel when they were martempered in the same condition.<BR>3. The common hard steel wire would have also the same properties as the card clothing wire by a slight control of the heat treating condition.<BR>4. The wire which had large size austenite grains showed smaller variation of the properties when the heat treating condition were changed.
