What is Grade B16 Fasteners ?

The ASTM A193 Grade B16 Fasteners are made up of a chemical composition which consists of elements such as chromium, molybdenum and vanadium. These fasteners are produced with the help of heat treatment. These fasteners are mostly used in applications where the environment is bound with high temperature or high pressure.

The chromium content in the alloy improves the durability of these fasteners. Whereas, the vanadium helps these fasteners to stay stronger even at highly elevated temperatures. These fasteners also have different characteristics such as Withstanding high volumes, flexibility, long life, outstanding scale precision, high strength, corrosion resistance, suitable surface finishes, and so on.

Sumit Impex is renowned for producing high-quality ASTM A193 Grade B16 Fasteners. They follow all rules and regulations, as well as industrial standards and guidelines, in order to produce a high-quality product.

The mechanical and physical properties of the A193 B16 Material standard contain strength properties ranging from 100 to 125 Ksi and elongation ranging from 16 to 18 percent. The A193 B16 Material standard is not corrosion resistant. If the client desires, these fasteners can be treated to increase their corrosion resistance. These fasteners undergo a series of tests in order to test and improve their quality. These tests include chemical tests, mechanical tests and so on.

Application Industries

These material are not a single material but the name for a family of corrosion resistant steels. Like many scientific breakthrough the origins of stainless steel lies in a lucky accident. From the smallest part of zipper to the largest building skyscraper, stainless steel is an essential part of modern life.Stainless steel’s strength, resistance to corrosion and low maintenance make it the ideal material for a wide range of applications. It is also has a long life cycle and is 100% recyclable.
