?? The dimensional tolerances of the outer diameter, inner diameter and length of the tungsten steel arc seal meet ±0.01, arc R1 meets ±0.1, arc R9-R9.68 meets ±0.01, and the actual size of arc R is detected by a profiler to meet precision processing requirements. , the entire tungsten steel seal is precision machined and then polished, resembling a candied haws, exuding a beautiful metallic luster. Material performance parameters are as follows: 1. Co content: 10%; 2. Density g/cm3: 14.45;…
