The silicon fasteners consists of niobium which provides the much required stabilization against the sensitization and the intergranular corrosion Silicon Bronze C65500 Stud Bolt has tremendous capacity of resistance to general corrosion. These are being designed in order to provide maximum resistance to acid attack and exhibits infinite resistance to stress based corrosion cracking in boiling 20% to 40% sulphuric acid. They have very good mechanical properties at both normal and higher temperatures up to a maximum of 930F. These are readily fabricated using the industrial methodologies. And the fabrication is being done at an ease. There are different standards which are being used depending on the requirement. The imperial size ranges from ¼” up to 6”. These are composed of copper, iron, carbon, chromium, manganese, molybdenum, silicon, sulphur, and nickel and phosphorous. These kind of fasteners are being utilized for a wide variety of applications namely pressure relief valves, centrifugal pumps and control valves. Depending upon the requirement they can be designed. The sizes and dimensions will vary based on the application. These fasteners do provide the much needed property of strength and durability.
