Possible applications of A2 AISI 304 stainless steel screws

A2 stainless steel (AISI 304) – The most commonly used stainless steel

The most commonly used stainless steel is A2. About one third of the volume in stainless steel production is this type of alloy. It belongs the group of conventional stainless steels.
There are many alternative designations used for this type of stainless steel. For example, it is also referred to as V2A or AISI 304. It is an austenitic stainless steel, which is also counted
amongst the group of non-corrosive high-grade steels (Inox stainless steel) owing to its nickel and chromium content. Basically, AISI 304 differs from A4 steel only in the absence of
molybdenum. As a result, it is less corrosion and acid resistant and is assigned to the lower Corrosion Resistance Class (CRC) II. The purposes for which V2A steel is suitable are regulated
by DIN EN 1993-1-4: 2015-10/Eurocode 3 and the General Building Inspectorate Approval.

A2 stainless steel and its main features

AISI 304 stainless steel differs from Inox A4 stainless steel because it contains no molybdenum. As a result, it is less resistant to corrosion and acid and is therefore only assigned Corrosion Resistance Class II. In the presence of salt and seawater, and media or atmospheres containing chlorine like in indoor pools, the material is not resistant. The tough alloy tends to harden during cold working. This makes it difficult to process by machining, drilling or punching. This grade of stainless steel is suitable for temperatures as low as -200 degrees Celsius.

Possible applications for V2A connecting elements and stainless steel screws

Stainless steel V2A screws do not rust in normal environments. Typical fields of application for connecting elements made of this type of steel include device assembly or wood fittings, including decking boards or wooden fences. However, the screws cannot be exposed to chloride or acidic environments. Constant moisture also causes A2 stainless steel screws to reach their limits. Other typical applications include kitchen appliances. This stainless steel is not suitable for use in indoor pools or seawater.

 

Typical application areas for connection technology made of AISI 304 stainless steel include:

  • Device assembly
  • Wood fittings
  • Kitchen appliances
  • Railings
  • Automotive construction
  • Beverage industry
  • Architecture
  • Domestic appliances
  • Sanitary units
