Alloy Steel Grade B5 Washers are durable and reliable components used to distribute the load of bolts, studs, or screws, ensuring secure fastening in machinery and piping systems. Manufactured from high-quality alloy steel, these washers are designed to withstand heavy pressure, high temperatures, and harsh industrial environments. Filiz Steel ensures every B5 Washer meets strict quality standards for performance and longevity. They are widely used in oil and gas, power generation, chemical plants, and construction projects. Their toughness, strength, and resistance to wear make them a dependable choice for critical applications requiring secure and long-lasting connections.
Alloy Steel Grade B5 Washers are made from carbon-chromium-molybdenum alloy steel with small amounts of manganese and silicon. This combination provides excellent tensile strength, toughness, and wear resistance. These washers can handle heavy loads, high pressure, and elevated temperatures without deforming. They also offer good corrosion resistance and fatigue strength, making them suitable for long-term use in demanding environments. With proper heat treatment, B5 Washers maintain their shape and mechanical properties, ensuring secure connections in both structural and industrial applications.
