seprator

Citizen Metals Pvt Ltd is one of the leading and well-reputed manufacturer, supplier, exporter and stockist of Stud. We are manufacturing these Stud in various shape and size.These bolts are made of AISI 302 stainless steel, which is reinforced by quenching and tempering. These flanged connections are designed for high-temperature applications. Citizen Metals is a leading supplier of ASTM A193 B7 SS Stud Bolts and other fasteners in a variety of sizes and forms. The material's tensile and yield strengths are both high. The diameters of stud bolts range from 3mm to 100mm in mm.

stud

The diameters vary between 3 and 4 inches. Minimum yield strength and minimum tensile strength of 80 and 100 ksi, respectively. The Stainless Steel 304 Stud Bolts have a maximum elongation rate of 16% and excellent hardness. Different types of bolts are made from distinct materials. Stud bolts made of 316 stainless steel are more resistant to corrosion and can be used in highly corrosive environments. The ASTM A193 specification includes multiple grades and classes, such as B7, B8, and B8M. M16 Stainless Steel Stud Bolts are utilised in automobiles, railroads, construction, and other high-strength and abrasive applications.
