ASTM F2281 Alloy 316 Bolts, ASTM F2281 Alloy 316 Nuts, ASTM A182 F2281 Alloy 316 Studs, ASTM F2281 Alloy 316 Threaded Rods, ASTM F2281 Alloy 316 Screws 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 in applications requiring heat resistance and high temperature effects at temperatures up to 1800°F (982°C). This standard covers a wide range of materials that can be used at high temperatures, as well as environmental considerations such as corrosive conditions caused by specific alloy characteristics. The specifications A276, A484/A484M, A493, A564/A564M, A582/A582M, and B637 are only supplied as material sources for bolts, hex cap screws, and studs manufactured to this specification.
