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=1×10⁵/4πA/m, its relatively magnetic permeabilityμ_r≤1.010

  When any distance by the inner hole is 100mm, its field gradient≤0.05μT
