What is ASTM A194 Grade 4 / Grade 16 Fasteners ?

ASTM A194 Grade 4 Fasteners are comparatively bigger as well as thicker compared to the other fasteners. These fasteners are used in applications which are bound with high temperatures as well as pressures. On the other hand the Grade 16 fasteners are also used in applications which are bound with high temperature or pressure or even both at the same time.

The grade 4 fasteners are highly resistant toward loosing and can withstand a temperature up to 500 degree celsius. ASTM A194 Grade 4 Fasteners also provide good strength at these highly elevated temperatures. The Grade 16 is made up of an alloy which contains about 11 percent to 13.5 percent of chromium in it. This addition gives these fasteners the desired physical as well as mechanical characteristics and hence makes them stronger and increases their resistance towards corrosion.
