Definitions
- the invention relates to the production of stainless structural steels which can be used in a wide range of applications for sheets, strips, tubes, rods, etc.
- a preferred field of application is the production of smooth or ribbed and also weldable reinforcing steel, i.e. of stainless reinforcement steels for reinforced concrete construction.
- Such stainless structural steels belong to the martensitic or ferritic-martensitic class and are given their intended properties by thermomechanical treatment.
- the intended properties of the rustproof structural steels are achieved once by thermomechanical treatment from the rolling heat, i.e. in the rolling process, and not achieved by annealing and subsequent cold forming.
- the intended properties according to DIN 488 Tl can be achieved by hot rolling with subsequent tempering.
- the annealing and cold forming can be omitted and stainless structural or reinforcing steel can be produced more cost-effectively.
- the cooling of the stainless reinforcing steel takes place after rolling from the
- Cooling pipes in water This creates a fine-grained soft martensitic or ferritic-martensitic structure of high strength and toughness, so that the requirements of the previous one
- a preferred composition of the reinforcing steel produced according to the invention is given when using material 1.4003 according to DIN EN 10088.
