Aatir Steel is a well-respected manufacturer and supplier located in Cairo, Egypt, recognized for providing top-notch industrial fasteners. One of their standout products is the Alloy Steel Gr 2H Washer, specifically crafted to handle the tough demands of high-pressure and high-temperature settings. These washers are made using cutting-edge techniques and rigorous quality control, ensuring they deliver outstanding durability, strength, and performance. Aatir Steel has earned a strong reputation for reliability and excellence, catering to a variety of industries throughout Egypt and beyond. With a focus on adhering to international standards, the company consistently offers products that uphold the integrity and safety of critical installations.
The Alloy Steel Gr 2H Washer is made from medium carbon steel, typically containing 0.40–0.50% carbon and 0.60–0.90% manganese, with maximum limits of 0.035% phosphorus and 0.040% sulfur. To boost its mechanical strength and hardness, the washer undergoes heat treatment. Its mechanical properties include a minimum tensile strength of 150 ksi (1034 MPa), a yield strength of 130 ksi (896 MPa), and a Rockwell hardness ranging from 24 to 32 HRC. These characteristics make the washer highly resistant to stress, fatigue, and deformation, ensuring dependable performance in demanding bolted joint applications.

Alloy Steel Gr 2H Washers are commonly utilized in industries where high-strength fasteners are crucial for safety and performance. This includes sectors like oil and gas, power generation, petrochemicals, construction, and heavy machinery. Typically used alongside Gr 2H bolts and nuts, they create a stable and secure load-bearing surface, reducing the risk of loosening due to vibration or thermal cycling. Their exceptional mechanical properties make them ideal for high-pressure piping systems, flanged joints, structural connections, and pressure vessel applications. These washers guarantee integrity and durability even in the most challenging operational conditions.
