Detailed Information
The A4 80 Bolt has a minimum tensile strength of 800 MPa. Prashaant Steel & Alloys is a major producer and supplier of A4-80 Metric Bolts of many kinds. The letter A in the name denotes that the bolt is made of austenitic stainless steel. The number 80 represents the minimum tensile strength, which is one-tenth of the tensile strength measured in MPa. Depending on the material properties, the A4-80 Stainless Steel Bolt can be found in grades ranging from 1 to 5. It’s an acid-resistant bolt composed of austenitic stainless steel that’s been cold worked.
The stainless steel used in the A4-80 Hex Bolt is generally 316 or 316L. The fasteners can also withstand temperatures ranging from 425 to 860 degrees Celsius. Carbon, silicon, manganese, phosphorus, sulphur, chromium, molybdenum, nickel, copper, and nitrogen are all present in varying amounts in the A4-80 Stainless Bolt. The Stainless Steel Bolts Grade A4-80 offer the required mechanical qualities as well as corrosion resistance due to this material composition. The minimum tensile strength varies depending on the material.
The a4-80 ss bolt has a hardness of 95HR B on the Rockwell scale and 217HB on the Brinell scale. There are a variety of fasteners in this series, including A4-80 Threaded Rod and screws. These bolts have a greater thermal conductivity. They have high electric resistance as well, and the size of the a4-80 hex nut vary depending on the standard. In general, they have a diameter of 6mm to 30mm. High tensile applications, acidic processing units, maritime hardware, and other high-temperature applications were among the applications.
