Details description
Chemical Composition
Carbon (C) content: 0.30%-0.50%, Silicon (Si): 0.30%-0.80%, Manganese (Mn): 17.0%-19.0%, Phosphorus (P) ≤0.05%, Sulfur (S) ≤0.05%, Chromium (Cr): 3.0%-4.0%, Nitrogen (N): 0.08%-0.12%.
Mechanical Properties
Tensile strength ≥530MPa, Yield strength ≥300MPa, Elongation δ5: 30%, Cold bending (180°d=2a) qualified, Permeability ≤1.05 high/Oe.
Performance Characteristics
Non-magnetic: Extremely low permeability, maintains weak magnetism in a magnetic field, effectively reducing the influence of magnetic fields on electronic and electrical equipment, suitable for occasions where magnetic field interference needs to be avoided.
Good corrosion resistance: The addition of high manganese and chromium enables it to withstand most common corrosive media, such as acids, alkalis, and salts, allowing for long-term stable operation in harsh environments.
High strength and wear resistance: It has high strength and hardness; the strength is even higher after heat treatment. Good wear resistance extends the service life of equipment and tools.
Good processing performance: Easy to process and weld; it can be formed by various methods such as forging, quenching, and heat treatment, meeting the processing requirements of various complex shapes.
Product Specifications
Common specifications include plates of (6mm-40mm) ×1.5m or more ×5m or more. It can also be processed into various forms such as bars, tubes, steel strips, wires, and forgings.
Application Fields
Widely used in shipbuilding, aerospace, machinery, and chemical industries. Specifically, it can be used to manufacture large and medium-sized transformers, electromagnets, and other non-magnetic structural materials. It can also be used to manufacture bearings, gears, shafts, and other components, as well as nuclear magnetic resonance imaging equipment housings, maglev train rails, and electronic component housings.
Stainless steel pipe offers durability and corrosion resistance.
