Alloy Steel Gr B16 Washers are produced from a chromium-molybdenum-vanadium (Cr-Mo-V) alloy and provide superior strength and corrosion resistance. The composition generally contains Carbon (0.30-0.50%), Manganese (0.60-1.10%), Phosphorus (≤0.035%), Sulfur (≤0.040%), Silicon (0.15-0.35%), Chromium (0.80-1.50%), Molybdenum (0.75-1.20%), and Vanadium (0.25-0.35%). These washers have a minimum tensile strength of 860 MPa, yield strength of 725 MPa, and elongation of 16%. They have excellent hardness (248-331 HB) and superior performance under high-pressure, high-temperature conditions.

Alloy Steel Gr B16 Washers find extensive applications in high-strength, heat-resistant, and corrosion-resistant industries. Petrochemical plants, power generation, oil & gas refineries, and heavy machinery are some of the common applications. The washers ensure safe fastening in high-pressure and high-temperature conditions and hence are suitable for boilers, turbines, heat exchangers, and pipelines. They are also applied in the construction of structural steel, aeronautics, and naval engineering, to provide stability and load transfer in bolted joints. Their superior mechanical properties render them vital in applications where reliability, durability, and stress resistance and wear resistance are of great importance.
