316L Stainless Steel Capillary Tube
316L stainless steel capillary tube has good flexibility, corrosion resistance, high temperature resistance, wear resistance, tensile resistance, water resistance and excellent electromagnetic shielding performance because of its small diameter.
It can be freely bent into various angles and radii of curvature, and has the same softness and durability in all directions; the axial tension can withstand more than 6 times the nominal inner diameter.
The corrosion resistance is better than 304 stainless steel capillary tube, and it has good corrosion resistance in the production process of pulp and paper. Moreover, 316L stainless steel is also resistant to erosion by marine and aggressive industrial atmospheres.
