What are stainless steel powder metallurgy materials?

With the development trend of contemporary powder metallurgy production technology, we can see the application of stainless steel powder metallurgy technology in electronic industry, motor manufacturing, state-owned economy, national defense industry and other industries. So, what are the stainless steel powder metallurgy materials? Here is a brief introduction of the Zhongwei Precision Editor:

Stainless steel powder metallurgy

1. Raw materials of cemented carbide tools

Carbide cutter is a raw material made of stainless steel powder metallurgy, in which one or more kinds of fireproof cementite powder is the main component, and cobalt powder is the adhesive. Common cemented carbide tools are divided into tungsten cobalt, tungsten cobalt titanium and tungsten titanium tantalum (niobium) according to their composition and characteristics. Cemented carbide tools have high toughness, high burning strength, excellent wear resistance and high tensile strength, but low bending strength and poor ductility. Excellent corrosion resistance and oxidation resistance. The linear thermal expansion coefficient is small, but the heat transfer coefficient is very poor.

2. Stainless steel powder metallurgy wear-resistant materials

Stainless steel powder metallurgy wear-resistant materials can be divided into iron based and copper based raw materials according to different base metals, and dry and wet raw materials according to different working standards. Wet raw materials are suitable for working in oil. Stainless steel plate powder metallurgy wear-resistant materials are used to produce clutch and brake systems for CNC lathes, large tractors, vehicles, mining vehicles, construction machinery and aircraft.

3. Raw materials of stainless steel powder metallurgy structure

Raw materials for stainless steel powder metallurgy structure can be divided into iron based raw materials and copper based raw materials according to different base metals. Compared with iron based structural raw materials, copper based structural raw materials have lower tensile strength, higher plastic deformation and ductility, excellent conductivity, heat transfer and corrosion resistance, and can be coated in a variety of ways, and are generally used to produce instrument and equipment components, household appliances and mechanical equipment commodity components, such as small control module transmission gears, camshafts, standard parts, gate valves, pins Sleeves are small in size, complicated in appearance, high in accuracy and small in bearing capacity.

Above is the key category of stainless steel powder metallurgy materials. According to the basic and main uses of different metal powders, stainless steel plate powder metallurgy products can be roughly divided into stainless steel plate powder metallurgy mechanical parts, wear-resistant materials, permanent magnetic materials and cemented carbide cutting tool raw materials. Among them, stainless steel plate powder metallurgy mechanical parts are the main products in the field of stainless steel plate powder metallurgy due to their wide use, large demand and high scientific and technological content.
