Alloy Steel Gr B6 Bolts are mainly made up of chromium and molybdenum, typically featuring around 5% chromium to enhance corrosion resistance and strength. These bolts are known for their impressive tensile strength, remarkable hardness, and ability to withstand high temperatures. Their mechanical properties include a tensile strength of about 760 MPa, yield strength of 585 MPa, and an elongation of roughly 20%. This blend of strength, toughness, and corrosion resistance makes Grade B6 bolts perfect for demanding applications in chemical, petrochemical, and high-temperature settings.
