What is Alloy Steel Gr B7 Washer?
Alloy Steel Gr B7 Washers are crafted from AISI 4140/4142 alloy steel, celebrated for its strength and heat resistance. The typical composition features chromium (0.8–1.1%), molybdenum (0.15–0.25%), and carbon (0.37–0.49%). These washers boast impressive mechanical properties, including a minimum tensile strength of 125 ksi (860 MPa) and a yield strength of 105 ksi (725 MPa). They undergo heat treatment to boost hardness and durability, making them perfect for high-stress applications. With excellent resistance to wear, fatigue, and corrosion, these washers ensure long-lasting performance even in tough operating conditions.
