Alloy 20 flat washers

Considered a “super” alloy of stainless steel, Carpenter 20 (also known as Alloy-20) is practically immune to chloride pitting… which is what makes it so popular within the chemical, food, plastic, and pharmaceutical industries.  Alloy 20 bolts  offer great resistance to stress-corrosion cracking in mid concentration sulfuric acid.  This can be seen in within the food and dye industry alloy-20 nuts are used in SO2 scrubbers.

With a tensile strength of 80ksi, Alloy 20 bolting offers the strenth for most applications while also highly resistant to corrosion in acidic applications, .  For additional information on the properties of Alloy 20 bolts and other fasteners, contact Lightning Bolt at 225-272-6200 or sales@lightningboltandsupply.com
