SS 446 Washers
What are Washers?
Washers are a type of fastener widely used in conjunction with bolts, screws, and nuts. They are thin, flat, and disc-shaped components with a hole in the center. Washers are placed between the fastener head or nut and the mating surface to distribute the load, prevent damage to the surface, and improve the integrity of the joint.
Load Distribution: By providing a larger bearing surface, washers distribute the load more evenly across the surface area. This helps reduce stress concentrations and prevents the fastener from digging into the material, improving the overall strength and longevity of the joint.
Alignment and Leveling: Washers can be used to compensate for slight irregularities in the mating surfaces. They help align and level the fastener assembly, ensuring a secure and proper fit.
Vibration Damping: The use of washers can help absorb and dampen vibrations, reducing the risk of loosening or failure due to dynamic forces.
Protection and Sealing: Washers can protect the mating surface from damage caused by the fastener. They also act as a barrier, preventing moisture, dust, and other contaminants from entering the joint, thereby enhancing its durability and resistance to corrosion.

They are used in equipment such as reactors, heat exchangers, and pipelines where resistance to high temperatures and corrosion is critical.
- Heat Treatment Equipment: Washers made from Stainless Steel 446 are commonly used in heat treatment equipment, including furnaces, ovens, and kilns. They provide reliable performance and longevity in environments with extreme heat and thermal cycling.
- Power Generation: Washers play a vital role in power generation facilities, including coal-fired and gas-fired power plants, where they are used in boilers, turbines, and exhaust systems. Stainless Steel 446 washers offer the necessary strength, corrosion resistance, and high-temperature performance required in these demanding environments.
- Automotive and Aerospace: Washers find applications in the automotive and aerospace industries, where they are used in engine components, exhaust systems, and structural assemblies. Stainless Steel 446 washers provide the required durability and resistance to thermal and mechanical stresses in these high-performance applications.
- Construction and Infrastructure: Washers are used in various construction projects, including buildings, bridges, and infrastructure. They provide stability, load distribution, and reliability in fastening applications, ensuring the structural integrity of the assembled components.
How Stainless Steel 446 Benefits the Quality of Washers
Stainless Steel 446 is a ferritic, heat-resistant alloy that offers several advantages for washer fasteners:
High Temperature Resistance: Stainless Steel 446 exhibits excellent resistance to high-temperature oxidation and scaling. This makes it an ideal choice for washers used in applications involving elevated temperatures, such as furnaces, heat exchangers, and exhaust systems.
Corrosion Resistance: Stainless Steel 446 provides good resistance to corrosion and oxidation, particularly in environments containing sulfur-bearing gases. It offers superior resistance to pitting, crevice corrosion, and chloride-induced stress corrosion cracking, ensuring the long-term integrity and performance of the washers.
Mechanical Strength: With its high tensile strength and good ductility, Stainless Steel 446 washers offer reliable mechanical performance, even under demanding conditions. They provide the necessary strength and load-bearing capacity to withstand the forces and stresses encountered in fastening applications.
Dimensional Stability: Stainless Steel 446 exhibits excellent dimensional stability, even at elevated temperatures. This ensures that the washers maintain their shape and structural integrity, contributing to the overall reliability and longevity of the fastener assembly.
Types of Washers Available
There are various types of washers available to suit different fastening requirements. Some common types of washers include:
Flat Washers: Flat washers have a simple design with a flat, smooth surface and a hole in the center. They are used to provide a smooth and even bearing surface, distribute the load, and protect the material surface from damage.
Spring Washers: Spring washers are designed to provide spring tension and maintain bolt preload in applications subject to vibration or dynamic loads. They help prevent loosening of fasteners and maintain the clamping force over time.
Lock Washers: Lock washers are specially designed to prevent loosening or rotation of fasteners due to vibrations. They feature serrations, teeth, or grooves that grip the mating surface and provide additional resistance to rotation.
Belleville Washers: Belleville washers, also known as conical washers or disc springs, have a conical shape and are used to provide high spring loads in compact spaces. They are commonly used in applications requiring high bolt tension or to compensate for thermal expansion and contraction.
When selecting the type of washer, consider factors such as the application requirements, load-bearing capacity, surface finish, and environmental conditions.
