Stainless Steel Machine Washers are components that are used to close the gap between fasteners and material surfaces. The washers also provide extra grip for the fasteners so that they could be fastened tighter. The SS 316 Machined Washer is one of the most commonly used washer type because of the chemical, mechanical and physical properties of the material.
The material has nickel, chromium and molybdenum in the composition and has high corrosion resistance. The Stainless Steel 304 Machined Washer is another type that is most commonly used. The 304 type is less costly than the 316 but the 316 has higher corrosion resistance, especially to sea water and chloride ion. Bot the washer materials have 215MPa minimum yield strength and 505MPa minimum tensile strength. The ss machined washer made of these materials can withstand temperatures up to 870 degrees Celsius as well. There are different types of washers with different dimensions according to the standard specifications.
There are square section spring washers, flat section spring washers, hardened washers and many other types that range from 5mm to 300mm in length, M2 to M100 in metric sizes and belonging to ASME B18.21.1. The SS 304 Machined Washer is used in different types of applications ranging from water lines, oil and gas industry, construction industry, petroleum industry an in general engineering applications. The different types such as the Machined Cup Washers are used with different applications depending on the requirements and purposes.
