Astm B473 Alloy 20 Specifications

A bolt is a type of fastener which is used to join two parts together. A bolt is a form of threaded

fastener with an external male thread requiring a matching pre-formed female thread such as a

nut. Bolts are very closely related to screws.

A fastener or fastening is a hardware device that mechanically joins or affixes two or more

objects together. In general, fasteners are used to create non-permanent joints; that is, joints

that can be removed or dismantled without damaging the joining components. Welding is an

example of creating permanent joints. Steel fasteners are usually made of stainless steel,

carbon steel, or alloy steel.

Because Alloy 20 provides greater mechanical strength to fasteners, it is more reliably at both

elevated and ambient temperatures. The alloy 20 bolts suppliers make fasteners that have

high-grade alloy. Other various types produced are slip-on, blind, long weld neck, socket-weld,

RTJ, and other items in addition to fasteners. Alloy UNS N08020 Fasteners have high resistivity

for pitting corrosion, crevice corrosion.
