Which steel fasteners are best for your application?
Stainless steel is different from other steel alloys because it doesn’t corrode or rust. Stainless steel is different from carbon steel due to the amount of chromium present. It contains minimum 10.5% to 11% chromium amount by mass, forming a chromium oxide layer which is inert. This is the reason for non-corrosive, anti-rusting attributes of stainless steel. Other than this, it has the basic properties of steel, as mentioned above.
Stainless steel is easy to fabricate and has a pleasing, aesthetic appeal. These properties, coupled by the fact that stainless steel has hygienic properties, makes it popular for consumer products and items that are used in food preparation and healthcare such as cookware and appliances, as well as, surgical instruments and hospital equipment.
Steel is the most common fastener material because it is strong and inexpensive when compared to stainless. Steel fasteners are available plain, as well as, with various surface treatments such as zinc plating, galvanization, and chrome plating. If aesthetics are not particularly important and the finished product will not be exposed to prolonged moisture, a carbon steel fastener would be a good choice for a commercial or industrial product for which function is more important than form – an application in which it simply has to work well, and not necessarily be the prettiest fastener.
