Abstract

According to the scheme, 316 austenitic stainless steel serves as a deformed steel base body to be machined, and the deformed steel comprises, by mass, 0.08% of C, 1% of Si, 2% of Mn, 0.35% of P, 0.03% of S, 10-14% of Ni, 16-18.5% of Cr, 2-3% of Mo and the balance Fe. The deformed steel has high strength and mechanical properties. According to the scheme, nitriding, co-permeation and magnetron sputtering are carried out on the surface of the deformed steel to form a composite film layer, the overall process is reasonable in design and easy to operate, and the prepared deformed steel has excellent surface wear resistance, high strength and high surface hardness, can be widely applied to the technical fields of various building construction, equipment machining and the like and has high practicability.

Description

technical field [0001] The invention relates to the technical field of special-shaped steel, in particular to a high-strength seamless special-shaped steel and a processing technology thereof. Background technique [0002] Special-shaped steel is the abbreviation of complex and special-shaped section steel, which belongs to a kind of section steel, and is different from the name of simple section steel. According to the different processes, it can be divided into hot-rolled special-shaped steel, cold-drawn (cold-drawn) special-shaped steel, cold-formed special-shaped steel, welded special-shaped steel, etc. Usually special-shaped steel refers to hot-rolled special-shaped steel. Hot-rolled special-shaped steel is a hot-rolled section steel that distinguishes square steel, round steel, flat steel and common shapes. [0003] As the application of special-shaped steel becomes more and more extensive, the research and development of the production process of special-shaped stee...
