Stainless Steel

Protocase Tech Tip Video

Premium solution to corrosion resistance.

Same stiffness advantage of steel yet even higher strength.

Non-painted Stainless is 'passivated' using Citric Acid to remove any iron contamination that may show up as rust spots.

Powdercoat, Passivate, Grained Finish

Typically use stainless fasteners and PEMS

Highly weldable (unless brushed)

Stocked Stainless Steel

304 Stainless Steel (A240 TP304 2B)

304 stainless steel has a high resistance to corrosion and lends itself to many types of fabrication, making it one of the most widely used forms of stainless steel used today. This alloys may be considered for a wide variety of applications where one or more of the following properties are important: resistance to corrosion, prevention of product contamination, resistance to oxidation, ease of fabrication, excellent formability, beauty of appearance, ease of cleaning, high strength with low weight, good strength and toughness at cryogenic temperatures, ready availability of a wide range of product forms.

The gauges shown above are based on American stainless steel sheet steel manufacturers gauge thickness. These will vary from british gauges with some exceptions.
