Main types of stainless steel powder metallurgy materials

With the development of modern stainless steel powder metallurgy manufacturing technology, we can see the application of stainless steel powder metallurgy technology in electronic industry, automobile manufacturing, civil industry, military industry and other fields. So, what are the main types of stainless steel powder metallurgy materials? Qinhuangdao zhongwei precision powder metallurgy gear processing factory shares:

1. Carbide materials

Hard alloy is made of stainless steel powder metallurgy, in which one or more refractory carbide powders are the main components, and cobalt powder is the binder. According to the composition and properties of cemented carbides, common cemented carbides are divided into tungsten cobalt, cobalt tungsten titanium and tungsten titanium tantalum (niobium). Cemented carbide has high hardness, high thermal hardness, good wear resistance, high compressive strength, but low bending strength and poor toughness. Good corrosion resistance and oxidation resistance. The linear expansion coefficient is small, but the thermal conductivity is very low.

2. Stainless steel powder metallurgy friction materials

Stainless steel powder metallurgy friction materials can be divided into iron based materials and copper based materials according to different base metals, and can be divided into dry materials and wet materials according to different working conditions. Wet materials are suitable for oil processing. Stainless steel powder metallurgy friction materials are mainly used to manufacture clutches and brakes on machine tools, tractors, automobiles, mining vehicles, engineering machinery and aircraft.

3. Stainless steel powder metallurgy structural materials

Stainless steel powder metallurgy structural materials can be divided into iron based materials and copper based materials according to different base metals. Compared with iron based structural materials, copper based structural materials have lower tensile strength, higher plasticity and toughness, good conductivity, thermal conductivity and corrosion resistance, and can be coated in a variety of ways. It is widely used to manufacture instrument parts, electromechanical parts, such as small module gears, cams, fasteners, valves, pins, sleeves, etc. The utility model has the advantages of small size, complex shape, high dimensional accuracy and small force.

These are the main types of stainless steel powder metallurgy materials. Stainless steel powder metallurgy products can be roughly divided into stainless steel powder metallurgy mechanical parts, friction materials, magnetic materials and cemented carbide materials according to the basis and use of metal powders. Among them, stainless steel powder metallurgy mechanical parts have a wide range of applications. High requirements and high technology content are the leading products in stainless steel powder metallurgy industry.
