What Are Hastelloy B2 Stud Bolts?
Hastelloy B2 stud bolts are corrosion-resistant fasteners made of a nickel-molybdenum alloy. The material comprises 55% chromium, 15% molybdenum, 30% nickel, and trace amounts of iron, manganese, carbon, and silicon. Because of their composition, these fasteners offer excellent resistance to reducing agents like sulfuric acid and hydrochloric acid. They also offer excellent resistance to pitting corrosion in heavily chlorinated environments like swimming pools or water treatment plants.
Properties of Hastelloy B2 Stud Bolts
Hastelloy B2 Stud Bolts exhibit superior strength to other grades of stainless steel fasteners due to their high nickel content. They also have excellent ductility—which means they can be bent without cracking or breaking—and respond well to cold working processes like threading or cutting without sacrificing strength or durability. Moreover, they are resistant to chloride stress corrosion cracking (SCC) under certain conditions, and they can be used in environments where other materials may not stand up well over time.
Applications of Hastelloy B2 Stud Bolts
Due to their corrosion-resistant properties and high tensile strength, Hastelloy B2 stud bolts are often used in industrial applications such as chemical processing plants and pharmaceutical facilities where corrosive elements are present. They are also commonly used on offshore rigs and boats that operate in saltwater environments since they can withstand tough marine conditions better than other metals. Additionally, since this grade is non-magnetic, it can be used for nuclear reactor vessels that require non-magnetic components for safety reasons.
Benefits of Hastelloy B2 Stud Bolts
The primary benefits of using these fasteners include their ability to resist corrosive elements such as chlorine compounds and sulfuric acid; their ability to resist pitting corrosion; their durability; their ductility; and the fact that they are non-magnetic which makes them great for use in nuclear reactors or medical imaging equipment such as MRI machines where magnetic fields must be kept at bay. Another benefit is that these fasteners have been approved by several international organizations, including ASTM (American Society for Testing & Materials), ASME (American Society Of Mechanical Engineers), API (American Petroleum Institute), DIN (Deutsches Institut für Normung) - German Institute for Standardization - European Standardization Organization).
UNS N10665 Stud Bolts are an excellent choice for many industries due to their superior corrosion resistance properties and good mechanical properties, including excellent ductility and toughness even after cold working processes like threading or cutting have been applied during production. Their use has been approved by numerous international organizations, including ASTM, ASME, API, and DIN. With all these features considered together, it's easy to see why so many companies rely on them when looking for a solution that will last through harsh environmental conditions while still providing high levels of strength.
