why alloy 20:
This grade is made up the blend of chromium, nickel and iron content. It is the austenitic alloy with great corrosion resistance ability in chemical reducing environments that contain sulfuric acids and other harsh chemicals. This version of the alloy is stable with niobium to resist intergranular attacks.
These fasteners provide a potential cost-saving option when compared to other alloy fasteners. Also, these fasteners are suitable for phosphoric acid, nitric acid, and aqueous salt solutions. These fasteners are a solid solution for the chloride stress corrosion cracking environments. These fasteners also resist crevice and pitting corrosion. Special consideration is taken in the account in chloride containing environment because of corrosion rate increases.
