Where Quality & Service Make The Difference
Stainless Steel
The "300" series of Stainless Steel is the most common. It offers the greatest resistance to corrosion. They are austenitic, non-magnetic, and resistant to most acids. They cannot be hardedned by heat treating but when work hardened they can become slightly magnetic.
Commonly used for cold heading of screws, bolts, washers , cotter pins, and stamped parts.
Items milled from bar, i.e Screw Machine parts, Hexagon Nuts.
Used for Machine, Cap, and Sheet Metal Screw. Other Items hot forged or cold headed. A superior grade of 18-8.
Same as 304 but improved for cold heading qualities. Does not work harden as well as previous three types. Most cold headed products are made from this.
Excellent corrosion resistance. Resists oxidation temp. up to 2,000 deg.
Better corrosion resistance than 18-8 because of higher % of Nickel & Molybdenum.
The "400" series will not progressivley rust but corrosion resistance is lesser than that of the "300" series. They are magnetic and are usually more inexpensive.
Used for Sheet Metal Screws. Can be hardened to 40 Rockwell C.
Items Milled from bar i.e Hexagon Nuts. Can be bright hardened.
Generally used in Production of Phillips Head fasteners when cost is an major factor.
