2.Inconel 718 description
INCONEL alloy 718 (UNS N07718/W.Nr. 2.4668) is a high-strength, corrosion-resistant nickel chromium
material used at -423° to 1300°F. Typical composition limits are shown in Table 1. The age-hardenable
alloy can be readily fabricated, even into complex parts. Its welding characteristics, especially its
resistance to postweld cracking, are outstanding. The ease and economy with which INCONEL alloy 718
can befabricated, combined with good tensile, fatigue, creep, and rupture strength, have resulted in its use
in a wide range of applications. Examples of these are components for liquid fueled rockets, rings, casings
and various formed sheet metal parts for aircraft and land-based gas turbine engines, and cryogenic
tankage. It is also used for fasteners and instrumentation parts
3.Fasteners package method
Often small hardware, fasteners and other parts are packaged in bags and displayed in bins or on hangers.
Bagging is the most effective way to package and organize small parts, while also being the most flexible
and affordable. In order to better protect the products during transportation, we will pack the packed
products in wooden cases.
4.Fasteners Application
A fastener (US English) or fastening (UK English) 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.
