Product Description:
ASTM A194 2HM nuts are heavy hex nuts designed to withstand high-pressure and high-temperature environments. They're made from carbon or alloy steel, heat-treated for strength. In cold forging, the raw material (usually steel wire or bar stock) is at slightly elevated temperatures, without heating the material to a molten state. This process ensures precise dimensions, improved mechanical properties, and enhanced surface finish.
