Definitions
- the invention now seeks to provide a method for producing anchor rods or anchor wires of the type mentioned at the outset, which are distinguished by high corrosion resistance and strength properties corresponding to the intended use.
- the method according to the invention is essentially characterized in that rods or wires made of rustproof austenitic or ferritic steel are cold-hardened, preferably cold-wounded, cold-rolled, cold, in order to achieve a yield strength ratio R P 0.2 / R m of at least 0.7 embossed or cold stretched, after which any heat treatment is avoided after the cold forming.
- Rods or wires made of stainless austenitic or ferritic steel have not previously been strain hardened in a way that makes them appear suitable for ground anchors or rock anchors.
