The main structure and key components of the pneumatic hoist in operation are commonly made of stainless steel (such as 304, 316L), aluminum alloy, galvanized steel, nickel based alloy, etc. The sealing components are made of fluororubber (FKM) or polytetrafluoroethylene (PTFE), and the specific material selection needs to be combined with the usage environment and performance requirements. The following is a detailed analysis of the main materials of pneumatic hoists:

1、 Main structural materials

stainless steel:

304 stainless steel: It has the ability to resist atmospheric oxidation, does not rust, and is corrosion-resistant in media containing acid, alkali, and salt. This material is widely used in fields with high requirements for rust and corrosion prevention, such as food factories, slaughterhouses, and pharmaceutical factories, as well as in fields such as marine engineering, shipbuilding, offshore oil platforms, and ocean transportation.

316L stainless steel: has higher corrosion resistance and is suitable for more harsh corrosive environments.

aluminium alloy:

Aluminum alloy material is lightweight and has good corrosion resistance, making it suitable for situations where equipment weight needs to be reduced.

Galvanized steel:

Hot dip galvanizing treatment is applied to carbon steel components to form a dense zinc layer, which is resistant to salt spray corrosion and suitable for outdoor use.

Nickel based alloys:

Nickel based alloys have excellent corrosion resistance and high-temperature strength, making them suitable for high temperature, high pressure, or corrosive media environments.

2、 Key component materials

Chain:

Chains are usually made of galvanized steel or nickel based alloys, balancing strength and corrosion resistance. For high-quality workpieces, using a chain type pneumatic hoist is more suitable.

Gear:

Gear components may be made of alloy steel and undergo heat treatment to enhance wear resistance.

Sealing element:

Seals are key components that prevent gas leakage and external impurities from entering, usually made of corrosion-resistant and high-temperature resistant materials such as fluororubber (FKM) or polytetrafluoroethylene (PTFE).

3、 Material selection in special environments

Chemical industry:

In the chemical industry, pneumatic hoists need to resist the corrosion of various chemicals, so corrosion-resistant materials such as stainless steel or nickel based alloys are usually selected.

Marine environment:

In marine environments, pneumatic hoists need to resist the corrosion of seawater and salt spray, so 316L stainless steel or other materials that have undergone special anti-corrosion treatment are usually selected.

High temperature environment:

In high-temperature environments, pneumatic hoists need to use materials that are resistant to high temperatures, such as certain special alloy steels or ceramic materials.
