Inconel 601 Fasteners

Inconel 601 Fasteners are made up of a nickel chromium alloy. The material comes in different grades according to the composition. The Inconel 601 material has aluminum, carbon, 21% chromium, copper, iron, manganese, 58% nickel, sulfur and silicon in the composition. There are different fasteners such as the 601 Alloy Shoulder Nuts, bolts, screws, washers, studs and threaded rods. Each of them comes in different types as well.

The material has 760MPa minimum tensile strength, 450MPa minimum yield strength and 42% elongation rate. The Alloy 601 Bolt can be used at high temperature applications due to the high melting point of the material. The material has 1411 degrees Celsius melting point. The material can be solution annealed to increase the hardness. The ASTM B166 Inconel 601 Nut comes in different types such as the hex nuts, square nuts and other types. Each fastener has a different dimension. The dimensions of the fasteners are covered by ASTM, IS, BS and other international standards. The specification for the Inconel 601 Hex Head Nuts and other fasteners of this grade is ASTM B166. The sizes range from 3mm to 200mm. The length of the fasteners range from M02 to M33. The Inconel 601 Hex Bolts and other fasteners are used in oil and gas, petroleum, petrochemical and other industrial applications as well.
