ASTM F2281 Alloy 600 Threaded Rods, ASTM A182 F2281 Alloy 600 Studs, ASTM F2281 Alloy 600 Bolts, ASTM F2281 Alloy 600 Screws, ASTM F2281 Alloy 600 Nuts Supplier in Mumbai, India.
The ASTM F2281 standard specifies the chemical and mechanical requirements for stainless steel and nickel alloy bolts, hex cap screws, and studs with a diameter of 1/4 inch or larger that are intended for use at temperatures up to 1800°F (982°C) and in applications where heat resistance and high temperature effects are critical. Due to unique alloy properties, this standard covers a wide range of materials that may be employed at high temperatures, as well as environmental requirements such as corrosive situations. The specifications A276, A484/A484M, A493, A564/A564M, A582/A582M, and B637 are only given here as possible material sources for producing bolts, hex cap screws, and studs to this specification.
