Continuous Screw Flights
Material: Carbon/Mild Steel
short production time, excellent overall rigidity and strength.
Easy to weld and assemble.
Although outer edge thickness is about 1/2 of inner edge thickness, the hardness of outer edge is almost doubled after cold rolled process there for it is much more wear-resistant than inner edge.
Note: 1. The I.D. tolerance of continuous flight is within the range of customer required I.D. + 5mm, the max O.D. should not exceed three times the required I.D.
2. For all the thicknesses that are not listed above, customizations are available when reaching the minimum order quantity of raw materials.
