Metal desktop box

What Materials Are Used When Making Instrument Enclosures?

KDM can offer instrument enclosures made of the following materials.

# 1. Stainless steel 304

Stainless steel 304 is low carbon austenitic steel.

The 304 stainless steel is acid-resistant and can withstand short-term temperature rises of up to 900 degrees Celsius.

This type is the main grade in the stainless steel family and contains a minimum of 18% chromium and 8% of nickel.

Such an amount of chromium content provides the formation of an oxide layer on the surface, which makes the steel resistant to various chemicals.

Also, this ratio of the elements in the composition of the alloy allows it to exhibit antiferromagnetic properties.

# 2. Stainless steel 316

This grade of stainless steel sometimes referred to as A4 stainless steel or marine grade stainless steel, is the second most common austenitic stainless steel after 304 types.

It contains alloys of iron, chromium (between 16-18%), nickel (10-12%), and molybdenum (2-3%), with small (<1%) quantities of silicon, phosphorus, and sulfur.

The addition of molybdenum provides greater corrosion resistance than 304, concerning the localized corrosive attack by chlorides and to general corrosion by reducing acids, such as sulfuric acid.

When cold worked, 316 can produce high yield and tensile strengths.

# 3. Carbon steel

High-grade carbon steel is a steel with a carbon content of more than 0.6% (up to 2%).

With the rise of carbon percentage in the mass, steel can become harder and stronger through heat treatment.

Regardless of the heat treatment, higher carbon content reduces weldability.

# 4. FRP 

Fiber-reinforced plastic is a high-strength, linearly elastic material used to reinforce concrete structures.

It is an alternative to steel reinforcement elements.
