A Stainless Steel A4-80 Stud Bolt is a specific type of threaded fastener designed for various industrial and construction applications. Here's more information about A4-80 stud bolts:
Material: A4-80 stud bolts are made from stainless steel of grade A4-80. The "A4" designation indicates the stainless steel grade, which is equivalent to 316 stainless steel, known for its excellent corrosion resistance properties. The "80" indicates the minimum tensile strength in megapascals (MPa), which, in this case, means the stud bolt has a minimum tensile strength of 800 MPa.
Corrosion Resistance: A4-80 stainless steel offers exceptional corrosion resistance and is well-suited for use in corrosive environments, including marine, chemical processing, and industrial settings. It can resist rust, staining, and corrosion even when exposed to moisture, saltwater, and various chemicals.
Design: Stud bolts have threads on both ends, which allow them to be threaded into two different components, typically with a nut on each end to secure them in place. They are often used in applications where the two components need to be joined tightly together.
A4-80 stud bolts find applications in a wide range of industries, including:
Marine and offshore: Due to their corrosion resistance, they are commonly used in shipbuilding and offshore platforms.
Chemical processing: They are used in pipelines and equipment that handle corrosive chemicals.
Petrochemical industry: Stud bolts are employed in refineries and oil and gas facilities.
Construction: They can be used in construction projects where high-strength fasteners are required.
Food and pharmaceutical industries: These industries require stainless steel fasteners to maintain cleanliness and prevent contamination.
