The Alloy Steel Gr B6 Washers are mainly made from chromium-molybdenum steel, which provides outstanding strength and resistance to corrosion. Typically, they contain about 5–6% chromium, while carbon, manganese, and silicon work together to enhance hardness and durability. These washers boast impressive tensile strength (around 125 ksi), solid yield strength, and remarkable resistance to oxidation even at high temperatures. They maintain their mechanical integrity under thermal stress, making them ideal for high-pressure and high-temperature environments. Heat-treated for a tough yet flexible structure, Alloy Steel Gr B6 Washers deliver dependable performance in critical applications.
