It's made from N1310 low carbon alloy-steel, refined and forged by strict chemical analysis to reach its mechanical properties. It has favorable low-permeability, high-strength mechanical properties, great splitting properties of corrosion resistance and excellent abrasion performance.
When MPS=1×105/4π A/m, its relatively magnetic permeabilityμr≤1.010
When any distance by the inner hole is 100mm, its field gradient≤0.05μT
