ASTM F2281 Alloy 310 Screws, ASTM F2281 Alloy 310 Nuts, ASTM F2281 Alloy 310 Threaded Rods, ASTM A182 F2281 Alloy 310 Studs, ASTM F2281 Alloy 310 Bolts 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 requiring heat resistance and high temperature effects and have a diameter of 1/4 inch or larger. This standard covers a wide range of materials that can be employed at high temperatures, as well as environmental conditions such as corrosive conditions caused by specific alloy characteristics.
A276, A484/A484M, A493, A564/A564M, A582/A582M, and B637 are only offered as material sources for producing bolts, hex cap screws, and studs to this specification.
