Stainless steel A4-80 Stud Bolts are essential components in various industries, and they are known for their high strength and exceptional corrosion resistance. These stud bolts are made from stainless steel A4-80, a grade synonymous with durability and reliability, especially in harsh environments. As a stainless steel A4-80 stud bolt manufacturer, Vision Alloys ensures that these bolts meet the stringent standards of ASTM A193, ASME SA193, and DIN 976. These standards certify that the bolts can withstand high pressure and temperature conditions, making them ideal for chemical plants, oil refineries, and offshore structures.
The composition of stainless steel A4-80 stud bolts includes a high content of chromium and nickel, along with a significant amount of molybdenum, which enhances their resistance to pitting and crevice corrosion. Typically, the alloy contains around 18-20% chromium, 10-14% nickel, and 2-3% molybdenum, with carbon content kept below 0.08% to maintain its corrosion resistance properties. This specific composition also allows these bolts to maintain their mechanical properties at elevated temperatures, providing reliability in demanding applications.
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.
As a leading stainless steel A4-80 stud bolt supplier in India, we provide a range of sizes and configurations to meet the diverse needs of our clients. Whether for securing pipelines, assembling machinery, or constructing infrastructure, our A4 80 bolts are designed to offer superior strength and longevity.
