Do you know materials of steel sleeve bearings?

1,142 Published by Aug 03,2018

Before introducing the classification of steel sleeve bearings materials, briefly introduce the basic concepts of ferrous metals, steel and non-ferrous metals.
1) Ferrous metals, also known as steel materials, include industrial pure iron containing more than 90% iron (carbon content less than 0.02%-0.04%%); cast iron containing 2% to 4% carbon, also called pig iron; carbon content less than 2.11% Carbon steel; and structural steel, stainless steel, heat-resistant steel, high-temperature alloy, stainless steel, etc. for various purposes. The broad ferrous metals also include chromium, manganese and their alloys.

2) Put the pig iron for steel making into a steel making furnace and smelt it according to a certain process to obtain steel. Steel products include steel ingots, continuous casting billets and direct casting into various steel castings. Generally speaking, steel generally refers to steel that is rolled into various steel materials. Steel is a ferrous metal but steel is not exactly equal to ferrous.

3) Non-ferrous metals, also known as non-ferrous metals, refer to metals and alloys other than ferrous metals, such as copper, tin, lead, zinc, aluminum, and brass, bronze, aluminum alloys, and bearing alloys. In addition, chromium, nickel, manganese, molybdenum, cobalt, vanadium, tungsten, titanium, etc. are also used in the industry, and these metals are mainly used as alloy additions to improve the properties of metals. Non-ferrous metals are usually classified into light metals, heavy metals, precious metals, semi-metals, rare metals and rare earth metals. Non-ferrous alloys generally have higher strength and hardness than pure metals, and have large electrical resistance and small temperature coefficient of resistance. steel sleeve bearings-2

4) Special metal materials include structural metal materials and functional metal materials for different purposes. Among them are amorphous metal materials obtained by rapid condensation process, as well as quasi-crystal, microcrystalline, nanocrystalline metal materials, etc.; and special functional alloys such as stealth, hydrogen, superconductivity, shape memory, wear resistance, vibration damping and the like. , as well as metal matrix composites and the like.

5) Common materials for steel sleeve bearings: In terms of material selection, depending on the use environment, different product performance requirements, such as toughness requirements, hardness and wear resistance requirements, rust and corrosion requirements, heavy load and impact performance requirements, etc.

The most common ones are ordinary A3 steel; 20 and 45 carbon steel; 20Mn, 40Cr, 42CrMo and other alloying elements; GCr15 and other bearing steel; 202, 304, 316 and other stainless steel; YG8, YG15 and other hard alloy steel. The steel sleeve bearings are widely used, and different materials are suitable for different working environments, which is not mentioned here.
