Abstract

The invention discloses a stainless steel part and a method used for machining the stainless steel part. The stainless steel part comprises following components including, by mass, 0.1%-0.3% of C, 0.05%-0.1% of Ni, 0.1%-0.4% of Mo, 5.0%-8% of Si, 5%-8% of Cu, 3.5%-5% of N, 3.5%-5% of rare earth elements and the balance Fe and inevitable impurities. The rare earth elements are included in the stainless steel part, and therefore the rare earth elements and the copper element can cooperatively improve the corrosion resisting capacity of stainless steel, and the service life of the stainless steelpart can be prolonged; and then, the nitrogen element in the stainless steel part is high, and it is guaranteed that a stainless steel pipe has good corrosion resistance, tensile performance and highstrength.

Description

technical field [0001] The invention belongs to the technical field of stainless steel processing, and in particular relates to a stainless steel part and a method for processing the stainless steel part. Background technique [0002] In the prior art, when manufacturing circular steel rings, it is usually difficult to complete it with one piece of equipment, and multiple processes are required to form a circular steel ring. Not only is the work efficiency low, but also the input of workers, labor The strength and so on are great.
