What is Alloy Steel Gr B6 Fasteners?
Alloy Steel Gr B6 Fasteners are mainly made up of chromium, molybdenum, and carbon, with carefully controlled levels of manganese and silicon. This specific alloy mix boosts tensile strength, hardness, and resistance to wear, corrosion, and high temperatures. The fasteners boast a tensile strength of about 830–950 MPa and a yield strength of around 700 MPa. They also provide excellent ductility, toughness, and impact resistance, making them ideal for high-pressure, high-temperature, and critical industrial fastening tasks that require durability and reliability.
