Stainless Steel: Stainless Steels are part of a family of iron based (ferrous) alloys, each having a chromium content of not less than 12 percent.  Chromium does not corrode; therefore stainless steel has a high degree of resistance to corrosion.  The higher the chromium content in the stainless steel, the greater the degree of resistance to corrosion.  In addition to iron and chromium, stainless steel also contains varying amounts of nickel.  Nickel gives the stainless steel even higher resistance to corrosion, and makes the stainless steel stronger, especially at high or low temperatures.  The reason why stainless steel does not rust, is its ability to spontaneously form a thin invisible oxide film coating on the exposed surfaces, which when formed, prevents further corrosion from taking place.  Stainless steel is an expensive material, but less expensive than the nickel alloy materials (monel, etc.).  It is stronger than steel, and monel.  It is always annealed.  It is almost never plated, as it needs no additional protection from corrosion.  There are many different alloys of stainless steel; the types most commonly used for rivets are: A-286, 302HQ, 304L, 305, 316, 347, & 430.  There are a wide variety of uses for stainless steel including: hardware, cookware, cutlery, surgical instruments, appliances, and as a structural material in buildings, and in the automotive and aerospace industry.

Large:  Large Flange Head.  In blind rivets, this style refers to a wide diameter protruding head, which is used when a large bearing surface is required.  Somewhat the same as a brazier head style in a solid rivet.

Steel:  (Also called Mild Steel and Low Carbon Steel)  This is the most common material for use in fasteners.  Steel is an alloy consisting of mostly iron, and a small percentage of carbon, (between 0.05 – 1.1%) It is the least expensive metal.  It is strong, has good workability, and can be produced in a wide variety of forms.  Its chief disadvantage is its susceptibility to corrosion (rust) in an un-plated, unprotected form.  Its other drawback, in aerospace applications, is that steel is about three times heavier than aluminum, while not offering any great advantage in strength.  Steel is magnetic.  Most mild steel used for rivets is heat treated, although there are some exceptions.  Most steel rivets will have some form of protective finish or coating when delivered from the mill (factory) to prevent corrosion.  Most steel for commercial applications will be plated zinc with a clear chromate.  Most steel for military or aerospace applications will be plated cadmium with a yellow chromate.  

Tubular:  Full tubular rivet. Similar to the semi-tubular rivet, but with a deeper drilled hole. Commonly used by the loose-leaf binder industry.
