## Abstract

An endless steel pressing band for continuous structure transfer of a surface designed to laminated products, wood chip boards and the like, is welded at a butt point and has an alloy which provides after the galvanic removing good and uniform structuring in welding seam zones, including alloying ingredients carbon 0-0.03%, silicon 2-4%, manganese 0.15-0.5%, chromium 11-14%, nickel 6-8%, and a balance of iron.

## Claims

### Claim 1

A method of galvanic structuring of endless pressing bands, including the steps of providing a steel band having a weld seam; treating the steel band in an acid bath; and selecting the steel band with the following alloying ingredients:
______________________________________ Carbon 0-0.03% Silicon 2-4% Manganese 0.15-0.5% Chromium 11-14% Nickel 6-8%, and a balance of iron. ______________________________________

### Claim 2 (depends on 1)

A method as defined in claim 1, wherein the alloying ingredients of the steel band are:
______________________________________ Carbon 0.01% Silicon 3% Manganese 0.25% Chromium 13% -Nickel 7.3% , and a balance of iron. ______________________________________

### Claim 3 (depends on 1)

A method as defined in claim 1; and further comprising the step of selecting the acid bath of the following composition:
______________________________________ Phosphorus portion 40-50% Sulfuric acid portion 30-40%. ______________________________________

### Claim 4 (depends on 3)

A method as defined in claim 3, wherein said acid bath has the following composition:
______________________________________ Phosphorus part 45% Sulfuric acid part 34%. ______________________________________

### Claim 5 (depends on 1)

A method as defined in claim 1; and further comprising the step of subjecting the acid bath to the action of direct current with a current density of 3 ampere/dm.sup.2.

### Claim 6 (depends on 1)

A method as defined in claim 1, wherein said treating includes galvanically treating an inner side of the steel band.

### Claim 7 (depends on 1)

A method as defined in claim 1, wherein said treating includes galvanically treating an outer side of the steel band.

### Claim 8 (depends on 1)

A method as defined in claim 1, wherein said treating includes galvanically treating an inner and an outer sides of the steel band.

### Claim 9

A steel band for galvanic structuring of endless pressing bands having a welding seam and treated in an acid bath, comprising the following alloying ingredients:
______________________________________ Carbon 0-0.03% Silicon 2-4% Manganese 0.15-0.5% Chromium 11-14% Nickel 6-8%, and a balance of iron. ______________________________________
