The Stainless Steel Nut Bolt can come under B7, B16, B8, B8M and so on. These different grades also differentiate the chemical compositions. There are alloy steel, chromium molybdenum vanadium alloys, heat treated and many other types. The sizes range differently such as the M10 Stainless Steel Nuts. These are used in high pressure, high temperature applications, valves, flanges, fittings, pressure vessels, chemical applications, petroleum applications and many other industrial applications. As a leading SS Nut Bolt manufacturer in India, we produce and supply the fasteners in different material grades and types. There are also different specifications and standards such as the F593c Black Stainless Steel Bolts. The black bolts are coated with black oxides so that the corrosion resistance of the bolts improves. Please feel free to contact us for more information on the fasteners and their prices.
