Problems solved by technology

[0004] The purpose of the present invention is to solve the problem that in the prior art, when stainless steel is traditionally manufactured, it is generally directly pressed and sintered, resulting in a large structural gap of the stainless steel, and the sealing cannot be further improved, thereby affecting the wear resistance of stainless steel. To solve the problems of strength, toughness and anti-rust ability, provide a formula and process of high-density stainless steel products based on powder metallurgy

Abstract

The invention relates to the technical field of powder metallurgy, in particular to a high-density stainless steel product formula based on powder metallurgy and a process thereof. The process comprises the following specific steps of ingredient preparing, ingredient mixing, pressing forming, and sintering, wherein ingredients comprise SUS304 or SUS310, copper powder and a lubricating agent, the SUS304 or SUS310 serves as main materials, the enough amount of the the SUS304 or SUS310 is ensured, the copper powder is 200-mesh copper powder, the content of the copper powder is 3% to 5%, the content of the lubricating agent is 1%, in the sintering process, the temperature of a sintering furnace reaches 1250 DEG C to achieve the copper melting point, and at the moment, the copper powder is molten. The manufacturing process has the beneficial effects that by adopting the manufacturing process, the structural gap of a stainless steel part can be reduced, so that the overall density of stainless steel is improved, and the wear resistance, strength, toughness and rust resistance of the stainless steel are further improved.

Description

technical field [0001] The invention relates to the technical field of powder metallurgy, in particular to a formula of high-density stainless steel products based on powder metallurgy and a process thereof. Background technique [0002] Powder metallurgy is a process technology for producing metal powder or using metal powder (or a mixture of metal powder and non-metal powder) as raw material, forming and sintering to manufacture metal materials, composite materials and various types of products. The powder metallurgy method has similarities with the production of ceramics, and both belong to the powder sintering technology. Therefore, a series of new powder metallurgy technologies can also be used for the preparation of ceramic materials, and stainless steel is the abbreviation of stainless acid-resistant steel, which is resistant to air, steam, water, etc. Weak corrosive medium or stainless steel is called stainless steel. Stainless steel can provide people with convenien...
