Processing process of wear-resisting anti-impact type pile foundation steel protective barrel

The invention discloses a processing process of a wear-resisting anti-impact type pile foundation steel protective barrel. 0.16-0.22% of Mn, 0.85-1.0% of Cr and 0.16-0.22% of Mo are added, so that the atomic activities of the elements C and N are improved, air mass formed by each atom can form strong interaction with dislocation to generate a yield platform, and relatively great stress is needed to be provided by the outside to start the dislocation, and therefore, the tensile strength is guaranteed to reach 675/Mpa, the percentage elongation after fracture is guaranteed to reach 18.20%, the end-surface shrinking percentage is guaranteed to reach 38%, the yield point elongation is guaranteed to reach 44.4J and the yield point elongation is guaranteed to reach 850/Mpa. The processing process of the wear-resisting anti-impact type pile foundation steel protective barrel disclosed by the invention can be used for improving the hardness and the wear resistance of the pile foundation steel protective barrel, and has the advantages of high strength, no pollution, good hardenability, less possibility in cracking and low degree of relaxation.
