Samuel Steels is a reputable manufacturer and supplier of Alloy Steel Gr B5 Washers, based in Abuja, Nigeria. The company has built a strong reputation for crafting top-notch fastening components that adhere to global ASTM and ASME standards. These Alloy Steel Gr B5 Washers are designed to perform exceptionally well in high-temperature and high-pressure settings, making them perfect for industries like oil and gas, petrochemical, power generation, and heavy machinery. Samuel Steels prioritizes quality assurance, precision manufacturing, and customer satisfaction, ensuring that their products are durable and reliable, meeting the rigorous demands of industrial and engineering applications both in Nigeria and beyond.
Alloy Steel Gr B5 Washers are manufactured using chromium-molybdenum alloy steel, with high chromium content (up to 5%), molybdenum, carbon, manganese, and other strengthening constituents. The washers have high tensile strength, hardness, and wear resistance. Mechanical properties are normally high tensile strength of about 860 MPa, good yield strength, and remarkable toughness even under severe stress conditions. Heat-treated composition in them increases hardness and fatigue and corrosion resistance, making them well suited for high-pressure and high-temperature conditions.
