Esha Steel is a prominent manufacturer and supplier of premium industrial fasteners in Kolkata India. We specialize in Alloy Steel Gr B5 Washers and offer high-strength, long-lasting solutions for the oil & gas, petrochemical, and power generation industries. Our washers are made to resist high temperatures and pressures, providing excellent performance and durability. With dedication to precision engineering and high quality standards, Esha Steel provides consistent products to suit customer requirements. Rely on us for high-grade washers that optimize the efficiency and safety of your applications.
Alloy Steel Gr B5 Washers are fabricated using chromium-molybdenum-vanadium (Cr-Mo-V) alloy steel to provide maximum strength and resistance to corrosion. The alloy has a composition of around 0.80-1.05% chromium, 0.15-0.25% molybdenum, and 0.25-0.35% vanadium, which is used to promote hardness and resistance to wear. These washers have excellent tensile strength (min. 125 ksi), yield strength (min. 105 ksi), and high toughness. They have a hardness range as 248-341 HBW and perform excellently in high pressure and high temperature conditions. Their enhanced mechanical properties make them applicable in critical applications of power plants, refineries, and heavy engineering industries.
