ASME Sa 193 Gr B8 Threaded rod and A193 Grade B8 Studs Manufacturer in India

While some applications require corrosion resistance, others may require high mechanical properties, and some more may need the alloy to deliver a good performance, without putting a dent in the pocket. In such an instance, the use of grade 304 stainless steel works out to be ideal. With moderate to good corrosion resistance and good mechanical strength, the ASTM A193 Grade B8 Bolt is a very popular alloy across all global markets.

ASTM A193 Grade B8 Bolts

It is easily available and very ductile. So the production of different shaped fasteners, including threaded kinds is possible without much effort. Though the austenitic microstructure means the alloy is soft, its mechanical strength makes it possible for the ASTM A193 B8 Threaded Rod to be used across various industrial applications. The material is resistant to several acids present in food, which is why the food industry also uses these fasteners such as the ASTM A193 B8 Nuts in their equipment. The content of chromium in grade B8 is about 18%, and so it can undergo passivation. During passivation, the chromium present on the surface of the A193 B8 Washer reacts with the oxygen in the air to form oxides. Once the entire surface of the alloy is covered by this oxide layer, there is no space for oxygen atoms to react with the elements below the layer. Hence, this passivating oxide layer formed on the surface of the ASTM A193 B8 Socket Head Cap Screws is what protects the metal from getting rusted. Oxygen usually forms iron oxide or rust, which is red in color in metals that possess less than 12% chromium in their chemical composition. And since the surface remains protected, the a193 b8 Hex bolts will not get corroded by oxidation.
