These washers are crafted to meet ASTM A193 standards, ensuring they deliver outstanding strength, durability, and reliability even in high-pressure, high-temperature, and corrosive settings. Thanks to their precise engineering and sturdy build, Alloy Steel Gr 2H Washers guarantee secure fastening and long-lasting performance. They’re commonly found in industries like oil & gas, petrochemical, power generation, marine, and heavy engineering, providing trustworthy solutions for critical bolted connections.
Alloy Steel Gr 2H Washers are produced from medium-carbon steel and are generally heat-treated for added strength and toughness. They have 0.40-0.50% carbon, 0.60-0.90% manganese, and negligible phosphorus and sulfur for achieving high hardness and wear resistance. These washers have a minimum of 175 ksi tensile strength, 105 ksi yield strength, and a hardness of 248-352 HBW, which is suitable for heavy-duty use. Due to their high load-bearing abilities and resistance to harsh pressure and temperature conditions, Gr 2H washers are extensively used in structural, oil & gas, and bolting applications at high pressure.
