1.4571 - AT A GLANCE
What kind of steel is the 1.4571?
Like other austenitic steels, stainless steel 1.4571, also know as the 6CrNiMoTi17-12-2, cannot be magnetized. Also it cannot be hardened by heat treatment. Cold forming of the material causes a change in the microstructure and therefore work hardening, which increases tensile strength, yield strength and hardness. It has very good corrosion resistance, under certain circumstances excellent weldability and high durability, which helps in applications like furnace parts, heat exchangers, brewery equipment and medical implants or for the storage and transportation of milk for example.
Properties
The 1.4571 is an austenitic stainless steel that is resistant, due to the addition of titanium, to sensitization at high temperatures. It is suitable for applications where heat-induced intergranular corrosion is a problem and a variety of aggressive environments.
- Austenitic stainless steel
- Austenitic chromium-nickel-molybdenum steel
- Seawater resistant
- Resistant to diluted sulphuric and hydrochloric acid
- Resistant to intergranular corrosion after welding
- Very good cold formability
- Very good weldability
- Non-magnetizable
Applications
Due to the stabilizing titanium in this material it can be used in environments with high temperatures as well as in corrosive environments like chlorides or sulphorus environments. It can be used for chemical processing applications and in the pulp and paper industry where chemicals and high temperatures are used/needed.
