Details description
Execution Standard
GB/T 699-1999.
Chemical Composition
It usually contains a high content of manganese (Mn), approximately 18%, chromium (Cr) at about 3%, carbon (C) at about 0.5%, and small amounts of silicon (Si), phosphorus (P), and sulfur (S). The specific composition may vary slightly depending on the manufacturer and standard requirements.
Mechanical Properties: After proper processing, it exhibits high yield strength. Some manufacturers produce this steel with a yield strength of around 585 MPa, and through special processes, the highest yield strength can reach 681 MPa. The tensile strength can reach 1120 MPa, and the relative permeability is low, as low as 1.008.
Performance Characteristics
Non-magnetic: As a non-magnetic steel, its permeability is extremely low, and eddy current loss in a magnetic field is minimal, well meeting the requirements for use in non-magnetic environments.
High Strength: With relatively high carbon content and after solution treatment, strength can be further improved through semi-hot deformation strengthening or cold deformation strengthening, enabling it to withstand considerable stress.
Acceptable Machinability: Although the processing difficulty is slightly higher than some ordinary steels, it can still undergo forging, rolling, and other processing methods, and can be made into various forms such as plates and bars.
Product Specifications
Different specifications of plates, bars, and tubes can be produced according to demand. Plate thickness, width, and length can be customized, and various specifications of bar diameters are available.
Application Fields
Mainly used in manufacturing non-magnetic protective rings for steam turbine generators and other components requiring non-magnetic properties. It can be used as a non-magnetic structural material in large and medium-sized transformers, electromagnets, and other equipment.
