Carpenter 20

Carpenter 20 is considered to be one of the "Super" alloys in the stainless steel world.  The alloy has been constructed to be highly resistent to acid attack, which is inheret due to its high nickel, molydbenum,copper, and chromium concentrations.  Carpenter-20 fasteners are also given many other names including Nicrofer 3620 NbTM, UNS N08020, Carpenter 20, CB 3TMCN7M,AL 20TM,Carlson Alloy C20TM,Nickelvac 23TM, DIN 2.4660. 
Regardless what you call it, alloy-20 fasteners is even resistant to the harsh conditions of boiling sulfuric acid at concentrations up to 40%.  This alloy is also used SO2 scrubbers and throughout the food, chemical, and dye industry.  Allow Thunder threads to be your sole source for Carpenter 20 fastners.  We stock and immense inventory of carpenter 20 bolts, screws, studs, washers, carpenter 20 nuts, and have the ability to provide custom "to print" parts.
