Types of Stainless Steel Used to Manufacture Compressed Air Equipment

Air compressorsDesigning and manufacturing compressed air equipment is a lucrative market to enter. One of the factors that will affect the durability and performance of your equipment is material. There are different materials to choose from for your compressed air equipment, but stainless steel beats them all.

This material is the ideal choice for your equipment’s interior components and fittings. Stainless steel pipe fittings are heat- and corrosion-resistant, hygienic, easy to fabricate and guarantee manufacture of durable equipment.

Here are some types of stainless steel you can choose for your compressed air equipment.

Austenitic Steels

These steels have austenite (a face-centred cubic crystal) as their base element. They also contain nickel and chromium and at times nitrogen and manganese.

Type 302 steel, for instance, contains 8% nickel and 18% chromium. Austenitic steel has outstanding corrosion resistance, durability, and tensile strength, making it a good option for the HVAC market.

Ferritic Steels

These steels contain ferrite (a body-centred cubic rock) as their primary element. They also include chromium and iron in various percentages.

Ferritic steels are the leading choice for compressed air system designers because of their corrosion resistance, heat resistance, low density and low thermal conductivity. Since this steel does not contain nickel, it is not affected by its erratic price fluctuations.

Martensitic Steels

These are low-carbon steels containing 12% chromium, 0.12% carbon and iron. The martensite in them makes these steels durable.

Very few martensitic steels are hence fully hardened through tempering. To enhance their corrosion resistance, martensitic steels now have nickel and nitrogen additions.

With these options, you will be sure to design superior equipment for your clients. Remember to specify details such as diameter when ordering your fittings. The available dimensions range from schedule 5S-160S with schedules 5-10S being the ideal options for compressed air systems.
